This thesis is combined with the project－"design and exploitation of Automotive Constant Drive-Shaft", which is undertaken by the topic team. Based on the structural simplification to three-dimension solid models of ball-cage type and three column-shaft type constant velocity joint, and the three-dimension solid models are obtained by conversion engineering. Altair/Hpermesh software is used here for generating the finite element mesh of key parts of ball-cage type and three column-shaft type constant velocity joint.
