Ensuring top-notch NVH performance post-installation of an electric axle demands meticulous overall product integration. The mounting brackets and decoupling devices, both out of the scope of the powertrain supplier, have a strong impact on the level of structure-borne noise generated at the cabin. The real usage of the axle can guide the development, focusing on the operating conditions at which the vehicle will be driven the most, hence impacting the overall subjective evaluation of the NVH performance. Furthermore, the integration and the surrounding components can have a strong negative impact on the efficiency of an acoustic encapsulation (when one is necessary to achieve airborne targets). Overall, robust integration and close collaboration between vehicle manufacturers and suppliers are paramount to converge to technical solutions combining cost-efficiency and excellent NVH performance.
