Shift force of manual transmission is an important index of vehicle performance evaluation.In this paper contains a detailed synchronizer, a simulation model of vehicle system can simulate the transmission process of a vehicle traveling in the synchronous movement of each block synchronizer simulation analysis handles the ball shift force characteristic curve.The simulation result of the shift force in conformity with the GSA test results. Based on the modular vehicle system simulation model for shift institutions and synchronizer optimization of structure parameters such as, can evaluate the shift quality of new products, such as synchronizer provides the reference for the design of key components.
