Globally, all automotive OEMs are shifting very fast towards hybrid & electric vehicles. The major challenge faced during electrification is replacing conventional powertrain with the electric one. Electric Powertrains are almost 3-4 times heavier & occupy more space than conventional powertrains for same power / torque output. To integrate the e-powertrain on a vehicle, many structural design modifications are required. Also, there is need to reduce the overall weight of the vehicle to compensate for additional battery weight. Structural modifications to reduce weight have an adverse effect on NVH performance of the vehicle. So, it’s a challenge to meet the weight target while maintaining NVH targets.

Also, the noise sources like Tire Noise, HVAC Noise, Wind Noise, Buzz/Squeak/Rattle which were masked by conventional engine sound earlier are now perceived in EVs with more intensity leading to driver/passenger discomfort.

Also, it’s a misconception that e-powertrains are quieter; in fact, their excitation frequency range are much broader compared to conventional powertrains though the SPL amplitudes are low. So, there is a need to extend the frequency range of NVH analysis to take those effects into account.

Also, in general the project timelines for Hybrid & EVs are much tighter & there is very less time to carry out multiple design iterations.

Join us for a LIVE webinar to learn about how Hexagon MSC Solutions can help to address these NVH challenges.

You'll learn:

  • Simulation techniques for e-powertrain noise
  • Methods for Lightweighting while meeting NVH targets
  • Simulation techniques to extend the frequency range of NVH analysis
  • Simulation techniques for noise sources like Tire, HVAC, Wind Noise
  • AI/ML techniques to carry out more design iterations in less time & thus taking better design decisions
  • Designing sounds for the Infotainment systems
  • Design of Automotive Vehicle Alert System (AVAS)
  • Methods for simulating passby noise
