NVH Simulation and Validation of a Coaxial eBeam Axle 2023-01-1131
Abstract: This paper describes the characteristics and advantages of a coaxial eBeam axle, and in particular, its NVH performance under various noise excitations including eMotor and the gearing system. The NVH CAE model of the eBeam axle is established, and structural vibration and noise radiation of the motor and gearbox are simulated and analysed. The results are used in the design optimization for NVH performance refinement. NVH validation test data is presented and compared with NVH simulation results, showing excellent correlation. Test data shows that the eBeam axle vibration and noise levels are well below the stringent targets.
