Design and Finite Element Analysis in Hydraulic Retarder Bracket Based on ANSYS

While hydraulic retarder installed on the transmission shaft, both ends of rotating shaft and transmission shaft are directly connected. It needs bracket to be fixed on the automobile frame, deformation of the bracket directly influenced the normal work and life span of the hydraulic retarder. So we must pay more attention to the strength of the bracket during our design. This paper obtained the stress state and the structural deformation situation under different structures, and confirmed the dangerous parts of the bracket by designing two different projects of the bracket and using ANSYS software to analyze the finite elements. It also provided a theoretic basis for further structure optimization and could be a reference for the similar product design.
