Taking transmission system of rail transit vehicles door as research object, virtual simulation and transmission stability of rotation roller screw are carried out. Firstly, modal analysis is made to get the natural frequency and vibration mode. Then with mnf files imported, rigid-flexible mixed virtual prototype of door system is established. Based on the vibration analysis of flexible screw, transmission stabilities of rail transit vehicles door are obtained. Finally, velocity profiles are
