Research on Evaluation of Firing Performance of Armament System Based on ADAMS

The significance and the necessity of virtual prototyping are discussed. The main characteristics of ADAMS are outlined, and ADAMS is first to be introduced into armament fields. The main fault modes that affect firing performance of artillery are analyzed, and three principles of performance evaluation are brought forward. Based on analysis of topology of artillery, with the application of Fortran language, the simulation module of artillery fault is programmed, and the virtual prototyping model is presented by using ADAMS. The evaluation plan of artillery performance with virtual prototyping is established, and the concept of evaluation function is defined. Finally, the perspective of virtual prototyping and the emphasis of next work are forecasted.
