Frontload qualitative NVH risk assessment

Electric machines are key elements to guarantee optimal vehicle performance, but they also have a strong impact on the system level NVH performance. The machine torque waveform may contain harmonics that may have implications on the control, power output, noise, vibration, and durability.

Being able to address those issues requires the implementation of a comprehensive process including the optimization of design trade-offs for torque and torque ripple by the machine designer, the machine’s vehicle level integration at various fidelity levels, and collaborations with the NVH teams to assess the influence of different design topologies and control strategies.

In this webinar, our experts will explain how to use simulation to improve the electromagnetic and vibro-acoustic design of e-machines, and to increase performance, reliability and durability levels.

Fine-tuning electric motors design for increased efficiency and optimal torsional vibration

During this 45-minutes session, we’ll introduce possible solutions to:

  • Optimize machine design efficiency while limiting torque ripple
  • Create and export machine models of various fidelities for system-level and NVH analyses
  • Check the impact of the integration of the selected e-machine in the driveline on torsional vibration
  • Optimize machine controls to limit torsional vibrations
  • Assess e-motor noise and identify system sensitivities during the conceptual design phase
