SimScale launches simulation features for compliance testing of electric vehicle components
German simulation software company, SimScale has released a set of new features for those engineers who are focused on the performance of structural and mechanical simulations for the automotive component supply industry. These simulations include large scale vibration analysis and modal-based harmonics.
The SimScale software is a cloud-native engineering simulation suite of components that are used throughout the automotive, manufacturing, medical, turbomachinery, building and electronics industries across the world, all of which share common analysis challenges in assessing vibration response of their product components.
With the release of the new modal-based harmonics capabilities in the SimScale software, engineers can now perform vibration analysis on complex CAD models using a single analysis type that automatically provides an output that includes full response spectrums for the design under consideration.
EV inverter vibration analysis
A good example of the way that SimScale can be used in the automotive industry is on the vibration analysis of an electric vehicle (EV) inverter. The company is using this example in demonstrations of how the software can be used and is available as an online resource or in live demonstrations. A computer aided design (CAD) model of an EV inverter is used to showcase the newly released modal-based workflow and show how a full shaker table test regime can be efficiently replicated by running multi-axis tests simultaneously with parallel computation in the cloud.
SimScale believes that these types of tests are critical in the product development process to comply with safety requirements and international standards. Using simulation to replicate physical tests can save engineers significant amounts of time and cost. The simulation model can highlight areas in which a physical test may show up product failures and enable the engineers to perform correct action before committing physical prototypes to test houses for validation. In this way both testing costs and lead times driven by test house availability can be reduced.
Simulation Using CAD files
The SimScale package operates with standard CAD output files. These files can be uploaded into the simulation software, where they will be prepared for FEA (Finite Element Analysis) simulation.
The software will perform accurate vibration assessments and can be used to apply global damping and automatically resolve resonant response around natural frequencies.
It can also simulate multi-directional shaker table testing in parallel and will post-process simulation results online and extract valuable insights about the products that are being tested.
As a cloud-based Software-As-A-Service (SaaS) application, SimScale provides instant access to CFD, FEA, thermal, vibration and electromagnetics analyses without the need for investing in on-site software and the hardware to drive it. SimScale has thereby moved high-fidelity physics simulation technology from a complex and cost-prohibitive desktop application model into a user-friendly cloud application, which is accessible via a more cost effective subscription-based pricing model.
