Study on Dynamic Simulation Calculation for Launching of Vehicle-gun

This paper focuses on dynamic simulation for launching of tank gun by the way of Kane methods. The article aims to supply for structure design and parameter optimize and analysis of firing density. The main contents are included as follows: The first, the model of classic interior ballistics is set up, in which there may be any mixed charges. The calculating program is designed. The second, the dynamic model is established for flexible bodies of tank gun. The third, the parametric and automatic are realized in the simulation software. Based on these, the dynamic simulation calculation is implemented, the predicted results are compared with test data and some of suggestions are put forward. The result indicates that the paper about dynamic simulation calculation is correct according to test.
