摘要
该文研究某自动迫击炮发射时的动力学仿真问题。在分析该火炮发射特点的基础上 ,把火炮系统简化成 3个刚体和一个弹性体组成的多体系统 ,建立了相应的动力学模型。重点考虑后坐部分变质量、多体动力学方程与内弹道方程的耦合等因素。通过数值仿真计算 ,获得了火炮连发时的运动受力规律 。
Dynamic simulation for an automatic mortar during firing is studied in this paper. Based on the analysis of launching characteristics, the mortar system can be simplified as a multi body system with three rigid bodies and one elastic body. The dynamic model is set up. Some important factors are considered, which include variable mass of recoiling parts and coupling between multi body dynamic equations and interior ballistic equations.The dynamic response of the system during continuous firing is obtained from numerical calculation,which can give reference to structural design and practical operation of such kinds of system.
