Research on Virtual Prototyping and Evaluation of Dynamic Performance of Armament Equipment

The significance of dynamic sumulation is emphasized,and the characteristics of buliding up virtual prototyping model are outlined.According to the topology and joint relation between two bodies of artillery system,the degrees of freedom and forces applied on recoil and counterrecoil mechanisms are analyzed.With the help of Fortran language,the virtual prototyping model of artillery is established by using ADAMS,the believability is validated by comparisons between simulation results and experimental results,the limitations of planar,symmetric and static equilibrium are freed,and the introduction of ADAMS into armament fields is validated to be feasible.Finally,gradational plan of performance evaluation is presented,the concept of evaluation function is defined,and the perspective of virtual prototyping is also forecasted.
