摘　　要：利用多体系统传递矩阵法,建立了链式炮系统的总传递方程和链式炮发射动力学仿真系统,得到了起始扰动以及火炮的动力响应。与相关的试验结果进行了对比分析。研究结果表明:将筋桶结构的长度增加6 mm后的仿真立靶密集度有改善,丰富了身管振动影响因素的研究内容,对于提高火炮射击精度具有应用价值。By using the multi-body system transfer matrix method,the total transfer equation of the chain gun system and the chain gun firing dynamics simulation system were established,and the initial disturbance and the dynamic response of the gun were obtained.The results were compared with the relevant test results.The research results show that the simulation vertical target density is improved after increasing the length of the rib barrel structure by 6mm,which enriches the research content of the influencing factors of barrel vibration,and has application value for improving the firing accuracy of artillery.
