Innovative NVH Testing and Simulation Methods for Eco-efficient Powertrain Engineering

With the increasingly tightened regulatory pressures to reduce emissions, the automotive OEM heavily draw the card of eco-powertrain development combined with lightweighting. The electric and hybrid vehicle market is progressing, but the internal combustion engine (ICE) will still represent the major part of the powertrain market up to 2030 and beyond. Accordingly, nowadays the powertrain development teams are strongly focusing on downsizing their ICE engines and transmissions in order to save weight and fuel while maintaining power and performance. Through the ECO-Powertrain project, the partners (SISW, Punch, KUL) react to this trend with a plan that will help OEM’s to achieve their eco-targets, while maintaining their high NVH standards. More specifically, the goal is to develop and validate new methodologies and tools for testing and simulation of downsized ICE powertrains, addressing the R&D challenges related to engine combustion noise, transmission induced NVH and driveline torsional vibrations, and enabling optimized designs with improved eco-efficiency and NVH performance.
