Lightweighting in EVs with Multiphysics Simulation

Lightweighting in EVs with Multiphysics Simulation

Abstract

Electric vehicles (EVs) tend to be heavier than internal combustion engine vehicles due to the heavy weight of battery packs. Because of this, it is becoming increasingly important to design car structures with advanced materials that are lighter while still strong. EV lightweighting can improve vehicle range, acceleration, and braking; reduce tire wear; and increase cargo capacity. Evaluating lightweight materials as well as optimizing structural designs involves accounting for different interacting physics phenomena, including structural mechanics, thermal stresses, and acoustic wave propagation. If you wish to learn how multiphysics simulation can aid the R&D of lightweight EV components and systems, join us for this live webinar.

We will discuss:

- Modeling composite materials for automotive lightweighting
- Evaluating the structural integrity and predicting failure; modeling buckling and delamination
- Modeling layered composite materials, including fiber-reinforced plastic, laminated plates, and sandwich panels
- Different approaches for modeling composite shells — layerwise theory and equivalent single layer theory
- Evaluating the micromechanical and macromechanical behavior of composites, including nonlinear composite materials
- How to couple composite laminates with multibody structural elements in a multibody system
- How to optimize composite layups, ply thicknesses, fiber orientations, and material properties
- Parameter, shape, and topology optimization of traction motors and load-bearing automotive components
