Automotive Acoustics Analysis Using COMSOL Multiphysics®

Abstract

Automotive acoustics play a vital role in vehicle design, encompassing the analysis of vibration and noise in mechanical components, optimization of ultrasonic sensors for parking and safety, the development of advanced car audio systems for precise sound reproduction, and the integration of smart systems and AI-enhanced functionality. This multidisciplinary field merges acoustics, structural mechanics, electromagnetics, and fluid dynamics to model and optimize key components essential for vehicle performance and passenger experience.

Attend this live webinar to see how the COMSOL Multiphysics® software can be used to model and analyze automotive acoustic phenomena. Topics include broadband cabin acoustics with integrated audio systems, acoustic packaging featuring absorbers and damping layers, and electroacoustic speaker design specialized for automotive applications.

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
