Automotive NVH Development - Past, Present, and Future Technology Challenges

Dr. Per-Olof Sturesson | Senior Director Driving Dynamics and Noise & Vibration Centre, Volvo Cars


The automotive market features a strong competitive environment that drives a high rate of innovation and development due to continuously increasing customer expectation. In addition new legal regulations, spanning from vehicle safety, CO2 to noise emission reduction, which often are contradicting regarding technical solutions, increase pressure on the product development capability and efficiency of the automotive OEMs. The innovation capability for an automotive OEM is therefore a top enabler for delivering sustainable corporate performance. An efficient product development gives competitive advantages as more products often can be put to market. 

One of the most important tasks during the vehicle development process in the premium and luxury automotive segments is the refinement of noise, vibration and harshness (NVH). Together with other attributes like styling, drivability and vehicle dynamics it strongly influences the overall perception of the vehicle. 

Over the last decades, the utilisation of CAE has increased substantially in the vehicle NVH refinement process. Today CAE is a fully integrated in the NVH development due to significant innovations in computer algorithms, application software and hardware systems. The numerous challenges with respect to NVH driven by the introduction of new technologies can be mitigated by means of extensive utilisation of CAE delivering products faster to the market. The presentation will cover a retrospective, current status and an outlook.

This presentation was recorded at the Global ATC in Paris, France on October 17, 2018.
