Abstract: Virtual
prototype of guns system during firing is created by using ADAMS, and
the normalized function of muzzle vibration is established. Relative
sensitivity analysis method is introduced to analyze effect of
structural parameters on initial disturbance. Thus the contrast problems
of structural design parameters with different dimension are solved, and
the parameters that affect initial disturbance most are achieved.
Furthermore, design parameters are optimized to minimize initial
disturbance with combination of virtual prototyping and SQP method. The
conclusion that the design parameters of gun involved should be further
improved is drawn, and it provides scientific references to design and
development of complicated military equipment. Finally, the perspective
of study on integrative performance of guns system based on virtual
prototype is presented.
