摘　　要：应用多体系统传递矩阵法,建立了某多管火箭系统动力学模型、动力学模型拓扑图、总传递方程、特征方程及动力学数值仿真系统,对比了不同工况下多管火箭系统动态特性;设计了射序和射击间隔联合优化连续变量,结合遗传算法,实例进行了以不同工况下最佳射击密集度为目标的最佳射序和最佳射击间隔优化设计,仿真结果表明,射击密集度提高了30%以上;基于单片机技术,研制了不同工况下自适应发火装置,取得了良好的工程应用效果,实现了多管火箭变射序变射击间隔发射技术。Based on the transfer matrix method for multibody system, the dynamics model of a certain multiple launch rockets system （ MLRS）, the topology figure of the dynamics model, the overall transfer equation, the eigenfrequency equation, and the numerical dynamics simulation system were established. The dynamic characteristics of MLRS in different working conditions were compared. The continuous variables were designed for joint optimization of firing orders and firing intervals. Combining with the genetic algorithms, the optimal design of firing orders and firing intervals for the purpose of the best firing dispersion in different working conditions was carried out on a real example. The results of simulation show that the firing dispersion is improved by more than 30%. Based on chip microprocessor technology, a self-adaptive firing device was manufactured, which receives good achievement in engineering application. Thus, the launching technique with variant firing orders and variant firing intervals by the MLRS provided was successfully realized.
