The primary goal for the automaton with two velocities design is satisfy the demand of fatal and non-fatal capabilities. Carry out parameter matching of two velocities automata key structure. Adopt multi-body dynamic theory, based on ADAMS software to establish simulation analysis model of 22 rigid bodies and 34 degree of freedom two velocities automata. Use different front/back gun quality, front/back recoil spring's stiffness and preloading matching scheme, analyze the kinematic characters of bolt, reliability of ejecting bullet's case and contact between front bolt and rear bolt are analyzed, and put forward influence rule of structure parameter on automata movement. The results show that, the method movement is coherence and stable, the automaton with two velocities is feasible. And it can realize fatal and non-fatal shooting and give technology support to two velocities design.
