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 ,对该类系统的结构设计和实际使用均有参考价值
Abstract:
Dynamic simulat ion for an automat ic mortar during f iring is studied in this paper. Based on the analysis of launching characterist ics, the mortar system can be simplified as a mult-i body system w ith three rigid bodies and one elast ic body. The dynamic model is set up. Some important factors are considered, w hich include variable mass of recoiling parts and coupling betw een mult-i body dynamic equations and interior ballist ic equat ions. The dynamic response of the system during continuous f iring is obtained from numerical calculat ion, w hich can g ive reference to structural desig n and pract ical operat ion of such kinds of system.
