Smaller engines, bigger challenges? Optimize the NVH of downsized engines
Reducing fuel consumption is a major concern of automotive manufacturers. The trend toward downsized internal combustion engines (ICEs) and higher torques at lower engine speeds have a positive impact on the vehicle’s fuel consumption, but also causes new NVH and drivability issues. The severity of driveline vibration issues depends on the combination and interaction of different components in the vehicle.
Instead of running isolated campaigns targeted at individual attributes, thereby generating redundant and sometimes conflicting models and data sets, Siemens PLM Software has developed a unified testing and modeling method to balance multiple attributes in an optimal way.
