【Abstract】Taking the shell of two-speed automatic transmission shift actuator as the research object，this paper analyses the stress of the shell and focuses on the areas where the shell is prone to failure. Then，the structural strength of the shell is checked by finite element simulation method and vibration test method，which verifies the reliability of the model and saves the cost and time for the final finalizing of the shell of the actuator.

【Key words】shift actuator；finite element simulation；vibration test
