NVH issue root-cause analysis & mitigation. Increased trends in electrification and associated technologies have posed new challenges in NVH development . In addition to minimizing tonal noise content in the vehicle’s interior, there are multiple potential NVH issues related to transient instabilities (e.g.
gear rattle or other driveline issues).

12/22/2020 · Karma Automotive established a strategic partnership with Simcenter Engineering and Consulting services to meet NVH performance targets and implement state-of-the-art NVH testing and simulation processes. Using the Simcenter tools and services for more than four years, Karma went beyond NVH optimization to optimize its overall development process .
NVH phenomena illustrate the complex nature of the driveline integration process . Therefore, early in the vehicle development process it is crucial to begin with driveline NVH evaluation, both through CAE and with prototype vehicle testing. During the entire vehicle development process , crucial NVH driveline metrics must be monitored carefully.
