Numerous cities around the world are facing changes in the way urban transportation is considered. The need for lower particle emissions and for a safer and quieter environment are key concepts shaping the future of mobility. Among sustainable transport system enablers, recent technological progresses in electric and autonomous vehicles are accelerating user adoption.
Designing electric and autonomous vehicles is a challenge for the NVH design and engineering teams that need to cope with increasing acoustic comfort expectations while dealing with new noise sources and structural designs.
For Scania, a world-leading provider of transport solutions, the acoustic comfort of drivers and passengers has always been of great importance in the design engineering process. Not only is a pleasant drive critical for buyers or commuters, but it also impacts health and productivity. Scania is focused on getting their vehicles up to speed with today’s acoustic expectations by addressing the level and quality of vehicle interior noise. The development of increasingly optimized NVH properties is supported by extensive testing and by the introduction of new methods based on vibroacoustic simulations. In this endeavor, the calculation team at Scania Bus decided to use the new capabilities of Actran Virtual SEA approach to assess the vibro-acoustic performances of their design at mid- and high frequencies.
