NVH Simulator 2019.1 released

28 Feb 2020

Improves electric vehicle modelling, extraction and real-time simulation of tonal electronic harmonics.

Brüel & Kjær Sound & Vibration Measurement A/S, the world’s leading supplier of advanced technology for measuring and managing the quality of sound and vibration, has released version 2019.1 of the NVH Simulator. This release brings a greatly expanded ability to model electric and hybrid vehicles, along with over 200 other improvements and enhancements.

Dave Bogema, Product Manager with Brüel & Kjær explains, “One of the challenges associated with electric vehicle sound is the phenomena of non-zero-crossing and 'negative' orders. These arise from the operation of the power electronics controlling the motor. Typically, this manifests as tonal harmonics increasing and decreasing in frequency simultaneously, centred around a higher frequency tone. These harmonics have been difficult or impossible to extract from a measurement.”

With the 2019.1 release, not only can these tonal harmonics be extracted from a measurement, but they can also be resynthesized in real-time driver-in-the-loop simulations using the NVH Simulator software.

Sound and vibration, or NVH, are amongst the most important elements vehicle manufacturers use to convey character, refinement and a sense of quality to customers. The NVH Simulator software enables automakers to create and evaluate virtual NVH prototypes, saving millions of euros on every vehicle programme and shaving months off development time.
