摘　　要：从火炮系统的结构特性和物理性能出发 ,研究某自动迫击炮的动力学参数影响规律 .应用多体系统动力学方法建立火炮运动微分方程 ,在此基础上构建动力学仿真平台 ,通过输入不同的火炮结构布置参数及连接刚度参数 ,进行多工况动力学仿真试验 ,寻求动态参数的匹配以减小弹丸出炮口时的炮口扰动 。Based on structural and physical performance of gun systems, the effects of dynamic parameters on response of automatic mortar are studied in this paper. The differential equations of motion are formulated using method of multi-body dynamics. Dynamic program is developed to conveniently complete simulation tests for various design cases. Matching of dynamic parameters is found to decrease muzzle disturbance, which include different structural parameters and connection stiffness. The above research can be used in overall arrangement and structure design of gun.
