Hydrogen Tank Analysis with WoundSim & Abaqus
Abstract:
The world’s energy industry is going through a fundamental change: the transition from fossil fuels to sustainable energies such as wind, solar, and nuclear. The auto industry in particular is the tip of the spear in this transition as it moves away from the internal combustion engine to electric-powered vehicles. The two primary methods for storing the energy used in electric vehicles is through chemical storage either in the form of a traditional battery or in the form of hydrogen to be used in a fuel-cell. In order to store an adequate amount of hydrogen to run the fuel-cell, high-strength composite overwrapped pressure vessels (COPVs) are used. Designing and analyzing such pressure vessels is easily performed using the specialized tool WoundSim. WoundSim is the replacement for the Wound Composite Modeler which was developed by Dassault Systems over a decade ago and had become the defacto industry standard for the analysis of COPVs. This discussion will cover the capabilities of WoundSim and how it is seamlessly integrated into the SIMULIA platform.

Title:
Vibration Isolation System Analysis using Composite Modal Damping in ABAQUS
Abstract:
The rubber isolators are generally used in internal combustion engines for mounting the peripheral components to isolate the vibrations from the engine block. The critical part of selecting the rubber isolators and designing the isolation system is usually done by tuning the frequency with various rubber stiffness materials. This analysis is typically performed experimentally and that requires prototype components. The vibration isolation system can be designed analytically in ABAQUS by predicting the frequency response of the structure with different rubber stiffness values using hyper-elastic properties. The composite modal damping option in frequency analysis provides accurate damping values based on the mass and stiffness contribution of each component to the natural frequency modes. This is more helpful when the assembly has multiple components including rubber, nylon and metal parts. The mass proportional fraction of critical damping and the stiffness proportional of critical damping for rubber and other materials in the model are provided during eigen-value extraction and ABAQUS calculates weighted mass and stiffness composite damping for each of the extracted eigen-modes. The composite modal damping data will be used in mode-based steady state dynamic analysis to predict the response of the structure. This method has shown better accuracy compared to the modal damping specified manually to each mode. This paper details the usage of composite modal damping option on a peripheral component connected to engine block.

Title:
Human Body Modeling in Abaqus/Explicit
Abstract:
The Global Human Body Models Consortium (GHBMC) previously developed a family of detailed finite element {FE} human body models (HBMs) for prediction of injuries caused by blunt impacts. These models were developed specifically for motor vehicle crash applications, but have since been applied to a wide array of applications. Until recently, these HBMs were not available for the Abaqus FE solver.
The objective of this effort was to convert the head and neck regions of the GHBMC 50th percentile male {M50} from LS-DYNA to Abaqus Explicit. After using automated Abaqus conversion tools, nine of thirteen material models were manually recalibrated. The Abaqus head and neck HBM material models included: elastic-plastic for bones, viscoelastic, hyperfoam, and hyper-viscoelastic for soft tissues, fabrics for cross-linked fibers, and axial connectors to model strain-rate dependent ligaments. Each converted material model was validated in isolated tension or compression. Subsequently, nine direct impacts to the face with varying impactor mass, velocity and shape and three validation cases for the neck were performed. All 12 validation cases fell within the range of experimental data and had qualitatively similar responses to the LS-DYNA Model.
A pilot study was performed to morph the M50 HBM to subject-specific HBMs with the goal of allowing engineers to design medical and consumer devices using digital twin models. A fully automated pipeline was developed and tested by morphing the head and neck model to the anatomy of a 53 year-old male with body mass index of 35.5.

Endurica EIE Fatigue Analysis of 6 Channel Road Load History for an Elastomeric Transmission Mount
Abstract:
The forces and moments acting on a hyperelastic automotive transmission mount occur in 3 coordinate directions, so there are in general 6 channels of input (3 forces and 3 moments) to consider in fatigue analysis. This presentation shows how load inputs recorded on the test track can be rapidly analyzed with Abaqus and the Endurica EIE software to obtain the strain history needed to compute fatigue life on a finite element model of a rubber mount. First, to minimize problem complexity and size, the recorded channels are checked for mutual correlation, and a reduced coordinate basis is identified that accurately represents the full signal with fewer dimensions. Next, a nonlinear mapping is constructed that relates the loaded states of the rubber mount to their associated stress-strain fields. A unique mapping between load states and stress-strain fields is assumed. The stress-strain fields of the mapping are then pre-computed via Abaqus for each grid point in the map. The resulting nonlinear map is then used to interpolate the pre-computed results to populate element stress / strain histories for each time step in the original 6 channel recording. Finally, the stress-strain history is used to compute fatigue life contours on the mount, using the Critical Plane Analysis implemented in the Endurica fatigue life solver. The workflow enables an analysis of recorded road load data that executes orders of magnitude faster than direct analysis, and produces results that are equivalent to within acceptable engineering tolerances.

Smart tools to Process, Report, Share, and Review Abaqus, fe-safe, and CST Results and Increase Efficiency
Abstract:
VCollab is a technology partner of Dassault Systems and has developed state-of-the-art smart tools to process, report, share, and review the Durability & EM results from ABAQUS, fe-safe & CST. The companies as well as the simulation experts are facing a number of challenges driven by the requirements and complexities of today’s products and processes. These challenges fall into the categories of resource demand, efficiency and communications. We learn from the industry that the CAE Analysts are spending ~35% of their time in manual and inefficient post-processing of simulation results and creating the CAE reports. Additionally, the CAE reports remained as the stack of PPT slides in 2D form. Because of the nature of these 2D static images, which make up a company’s simulation report, it’s often hard for other stake holders in the organization to fully understand the impact of these results on their product’s performance. Additionally, the size of native CAE results files is very large which limits the ability to share these results across the organization. VCollab developed smart tools to address these issues.
In this presentation, VCollab will discuss and demonstrate smart tools for easily automating and processing simulation results, as well as how to create Digital CAE Reports that will assist companies in conducting efficient design reviews and making faster design decisions. Analysts would learn faster and more efficient methods of processing simulation results and producing CAE reports. Analysts would also learn how to create 3D Digital CAE Reports so that they could easily explain their simulation insights to their customers. CAE methods teams would learn more efficient and intelligent ways to automate the post-processing and reporting process, as well as how to create Digital CAE Reports. IT Teams would learn new methods for storing key simulation results for long-term archival, as well as how to integrate Digital CAE Reports into the DOE/PLM/SLM/SPDM systems. Companies learn to use these Digital CAE Reports as part of their Digital Transformation initiatives, and as a result, they benefit from making faster design decisions and bringing their products to market faster.

Fatigue Durability of Heat Exchanger Fins
Abstract:
Although small scale fatigue cracking of the fins of nearly all heat exchanger designs are considered only aesthetic, a heat exchanger manufacturing client has invested in extensive analysis and testing to develop proof that any such fatigue cracking on one their newly designed fins would indeed be aesthetic only. Optimal usage of Abaqus tools to develop structural analysis for the heat exchanger which shows the progression from the large-scale outer boundary conditions to refined fatigue analysis with fe-safe is discussed. Correlations between the fe-safe analytical results and physical lab testing are also discussed and is the main point of this paper. Ultimately, it was proven that the fins should not be a structural concern in the field.

Title:
Hitched: Trailer Load Calculation Using True-Load Load Reconstruction
Abstract:
When modeling automotive applications, the need to understand real world loading is imperative for proper simulations. Traditional approaches may use company standards or even MBD simulations. However, these approaches are at best approximations of the actual load conditions. If using an approximation of loading in a simulation, the results are only as accurate as the approximation. Companies often use experimental load transducers to measure real world loading. There are two major disadvantages with this approach. The first is that the load transducers often cannot measure all of the desired load inputs for a simulation. The second disadvantage is that the application of the load transducer forces physical modifications of the subject components. The measured loads may not be the actual loads because of the mass and stiffness changes to the subject components. Experimental Load Reconstruction is a non-invasive solution to this problem. The commercial True-Load® Load Reconstruction software will be demonstrated in this application. The unmodified trailer hitch is used in this application with only uniaxial strain gauges applied to the trailer hitch.
Presented will be an example of using True-Load Load Reconstruction technology to understand complex loading on an automotive trail hitch. This approach will involve the creation of an FEA model of the automotive trailer hitch. The automotive trailer hitch will have unit loads applied to the hitch. These unit loads will be used to construct a correlation matrix relating strain response to exterior applied loading. The operation of the hitch will be used with the application of commercially available types of payloads. These payloads can be trailers or RVs over various road conditions: city, highway, country, and rough roads.
The advantage in this approach is to get real world structural loads which can be used to drive accurate FEA simulations. Every trailer event is different; thus, the loading profiles are different. Traditional analytical techniques idealize the road surfaces and loading environment. The real world is complex, and every event is unique. True-Load loads provide real world loads for real world simulation.

Title:
Ensuring Structural Compliance of Electric Vehicle Battery Pack Against Crush Load & Fatigue Damage
Abstract:
Lithium-ion batteries are currently used for the new generation of electric vehicles (EVs) due to their fast-charging rate enabled by high energy density and cell voltage. Battery safety is the primary concern for these new generation electric vehicles. The high amount of energy stored in EV battery packs translates to higher probability of fire in case of severe deformation of battery compartment due to automotive crash or impact. Usually, an EV battery catches fire due to its thermal runaway where exothermic reaction takes place between flammable electrolyte and highly active material of the battery. The thermal runaway produces increasingly high temperature, often leading to a destructive result which may be fatal to the EV occupant.
This present work describes a methodology to simulate crushing of an automotive battery pack as per ISO 12405-3:2014 standard and evaluate the crashworthiness performance of the battery pack. Nonlinear code like SIMULIA Abaqus helps to accelerate the battery development process and to improve the final products. Complete battery pack consisting of multiple modules along with enclosure and connections are considered for the finite element analysis (FEA). Nonlinear explicit dynamic analysis is performed to simulate the crushing of battery pack in Abaqus FEA software. This study extends to evaluate fatigue analysis and performance of the battery pack using SIMULIA fe-safe (a leading durability and fatigue analysis software for FE models). We propose design changes as a result of the simulation analysis conducted to improve/optimize the fatigue performance.

Title:
Ensuring Structural Compliance of Electric Vehicle Battery Pack Against Crush Load & Fatigue Damage
Abstract:
Lithium-ion batteries are currently used for the new generation of electric vehicles (EVs) due to their fast-charging rate enabled by high energy density and cell voltage. Battery safety is the primary concern for these new generation electric vehicles. The high amount of energy stored in EV battery packs translates to higher probability of fire in case of severe deformation of battery compartment due to automotive crash or impact. Usually, an EV battery catches fire due to its thermal runaway where exothermic reaction takes place between flammable electrolyte and highly active material of the battery. The thermal runaway produces increasingly high temperature, often leading to a destructive result which may be fatal to the EV occupant.

Title:
EMC Analysis of Component Metallic Housings
Abstract:
Electromagnetic compatibility or EMC of electronic components have been a major focus as wireless technology proliferates industry. For various reasons many electronic products designed today are encased in a metallic enclosure. This enclosure is often viewed as an shield for unwanted electromagnetic energy to radiate from the product or radiate into the product from the outside. While this assumption may hold true in some cases there are factors to consider in a case design that will help or hurt the electromagnetic shielding performance. This presentation will explain and demonstrate aspects of shielding for electromagnetic interference and how these enclosures can be modeled using CST Studio Suite.

Title:
Dynamic CT and Opportunities for Advancement of Validated Modeling & Simulation
Abstract:
Advancements in modeling and simulation have been accelerating over the past three decades and have largely focused on replicating real-world object behavior. With the integration of Industrial CT, modeling and simulation has adapted to incorporate real product geometry and physics affecting a product’s quality and performance. New technologies are being integrated to provide real-time, dynamic CT scanning yielding behavioral geometries, deformations, and loads collected during the X-Ray process. Dynamic scanning allows for expanded input and validation metrics across the modeling and simulation spectrum, with the addition of time-based interpretation.
Models created from scan data are often large and require more compute resources. The latest iteration of the SIMULIA Cloud platform allows users to scale up on demand and solve these larger scan-based models fast enough to meet strict project deadlines.

Title:
Differences between Open Road Domain and Wind Tunnel Domain using CFD simulations
Abstract:
Automakers know that an electric car’s range is very sensitive to the vehicle's coefficient of drag. In order to optimize the coefficient of drag, Cd, for a specific vehicle, many hours of computational fluid dynamics simulations and physical tests are spent. However, due to the different boundary conditions, i.e. open road domain or closed loop wind tunnel, the results can be different. This study investigates the flow field differences between an automotive full-scale wind tunnel and open road conditions on a production electric vehicle using CFD.

The Evolution of CAE Methods at Dana
Abstract:
There are many factors that influence the development of CAE methods in an organization. This presentation will show how one of those factors, the pursuit of capturing failure modes seen in lab testing, has driven the development of one aspect of CAE in Dana. “Lessons learned” from several case studies will be presented. They will illustrate the necessary progression from simple models to the more complex models being built today, that required Dana to purchase and utilize Abaqus throughout the Dana enterprise. Our latest methods, while still advancing, have transformed our ability to predict many component failures and optimize complex systems, while minimizing the time taken to do so.
