Vehicle Modeling and Simulation: ICEV & BEV Correlation Procedure
Vehicle Level Simulation is a rapidly expanding technique which most OEMs are exploring to help reduce testing cost and time. To be effective, these simulations must accurately represent the vehicle being simulated. This can be achieved in two steps, first by collecting the data required for modeling and feeding it into a simulation tool to […]
Accelerate Electric Aircraft Design Certification with Systems Simulation
Electric Aircraft Are the Future The aviation industry has long imagined a future with electric aircraft. Development has started on smaller scales with aircraft such as electric vertical take-off and landing aircrafts (eVTOLs), short take-off and landing aircraft (e-STOLs), and others. According to a May 2022 study by Aviation Today, e-aviation has potential of […]
Sensitivity Analysis: How to Rank the Importance of Battery Model Parameters Using Simulation
What is Sensitivity Analysis? Sensitivity analysis is the study of how uncertainty in a model output (or response) can be attributed to different sources of uncertainty in the model inputs (or factors). These analyses are powerful tools for modeling and simulation activities, as they allow the modeler to identify the most and least influential parameters […]
Using Simulation to Model Closed-Cycle Argon Hydrogen Engines
Evaluating Renewable Hydrogen Fuel With the increasing demands for fuel-efficient and low-to zero-emissions technologies in the automotive industry, renewable hydrogen fuel is regarded as a promising energy storage form for vehicles. Pure hydrogen combustion emits no greenhouse gas CO2, and noble gases can eliminate environmental pollutants such as NOx by replacing nitrogen. As a result, […]
How a Catastrophic Ship Fire Reminded us Why Battery Thermal Runaway Simulation is Important
A few weeks ago, a 656-foot-long ship known as the Felicity Ace caught fire in the North Atlantic as it was transporting its cargo, including various automotive luxury brands, from Germany to Rhode Island. The fire broke out in the ship’s hold and continued to spread. Thankfully, all 22 crew members safely abandoned the vessel. […]
