Optimization and Application of Bearing Support for Output Shaft of C-EPS

Abstract:

In order to obtain the optimal situation of the output shaft load in different bearing support system, this paper has established output shaft load calculation model in one bearing, double bearings and three bearings support system to compare the calculation results. Use equivalent output shaft to do theoretical calculation and use finite element method to calculate the strength and stiffness of the uniform output shaft for comparison among three types of support. The results shows that stress value of output shaft with theoretical calculation is closed to the value with finite element method, but reverse as the deformation of output shaft, and the optimization values are less than 1% with three supporting bearings.
