Optimization design and fracture analysis of shift fork shaft of the transmission

Taking the shift fork shaft of transmission as research object, through analyzing the position and shape of the fracture on shift fork shaft, the paper gives the optional design scheme of shift fork shaft. The three dimensional mathematical model of the optimized shift fork shaft is set up by use of Pro/E software and the finite element analysis is carried out by ANSYS Workbench software. The analysis results show the strength of the optimized shift fork shaft can meet the design requirement.
