NVH Simulation and Validation of a Coaxial eBeam Axle

This paper describes the characteristics and advantages of a coaxial eBeam axle and its NVH performance under various noise excitations including both motor and gearing system. The NVH CAE model of the eBeam axle is established to assess the NVH performance and conduct optimization upfront. The physical test data of the eBeam axle that is incorporated with the proposed optimization solutions is presented, showing that the eBeam axle vibration and noise levels are well below the internal stringent targets.
