英文摘要：

Shock buffered mechanism is a key part of guns which plays an important role in guns system.The virtual prototype is established,and the effect of design parameters on dynamic performance of shock buffered mechanism is studied with introduction of relative sensitivity method,and the comparison problem of design parameters with deferent dimension is solved.The evaluation model of dynamic characteristics of shock buffered mechanism is constructed,and the definition and related conception of weakness score of index are brought forward.Then the method to confirm improvable chain of a system is given,and the simulation and improvement case suggest the efficiency of method and the superiority of virtual prototyping technology.The perspective of virtual prototyping technology applied in military equipment is presented.
