Multiphysics Simulation for Enhanced Electric Drivetrain Efficiency

The performance of EVs is largely dependent on the performance of the electric drivetrain. Improving the efficiency of the drivetrain involves addressing an interplay of different physics phenomena, such as electromagnetics, vibrations, heat transfer, and solid mechanics. Multiphysics simulation plays a crucial role in modeling such phenomena and enabling an agile process for the R&D of electric drivetrain components.

Join us for this live webinar to learn about using modeling and simulation to improve electric drivetrain efficiency. This webinar will include live demonstrations and a Q&A session.

We will cover:

• - Modeling permanent magnet motors, induction motors, and linear motors
• - Combining different physical effects to model phenomena such as structural stresses, rotor-induced vibrations, noise emission, and temperature rise due to power dissipation
• - Examining and optimizing parameters influencing motor efficiency, such as rotor torque as well as iron and copper losses, including the effects of temperature rise
• - Topology, parameter, and shape optimization for improving electric motor designs

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
