摘要/Abstract

摘要： 研究履带式多管火箭发射动力学特性并与轮式多管火箭动态特性分析对比，为提高多管火箭射击密集度提供直接的方法。应用多体系统传递矩阵法和发射动力学理论，建立了履带式多管火箭发射动力学模型及振动特性、动力响应分析和仿真系统，振动特性仿真得到了试验验证。对某轮式和履带式多管火箭振动特性、动力响应、火箭弹起始扰动、射击密集度进行了对比分析。对比分析结果表明，对同一批次火箭弹，轮式和履带式多管火箭的振动特性、动力响应和射击密集度有一定差异，履带式多管火箭的动态性能优于轮式多管火箭。分析结果为提高多管火箭射击密集度提供了直接的方法。

Abstract: The launch dynamics characteristics of tracked multiple launch rocket system (MLRS) were studied and compared with the dynamics characteristics of wheeled MLRS, and a method to improve firing dispersion was proposed. The launch dynamics model, vibration characteristics, dynamics response analysis and simulation system of a tracked MLRS were developed by using the transfer matrix method of multi-body system and launch dynamics theory. The simulation results of vibration characteristics were validated experimentally. The vibration characteristics, dynamics response, rocket initial disturbance and firing dispersion of wheeled and tracked MLRS were compared and analyzed. The analysis results show that there are some differences among them. The dynamics characteristics of tracked MLRS are better than that of wheeled one.
