摘　　要：多管火箭炮系统阻尼是系统动态响应的重要参数,对连射时序和射击间隔有着重要的影响。针对多管火箭炮的典型结构,从理论上分析了影响系统阻尼特性的典型因素,运用多体动力学方法建立的计算模型进行仿真分析,仿真结果与理论分析一致。研究结果表明发射装置起落架与回转体间约束副的摩擦效应、起竖油缸阻尼效应、部件的弹性变形对多管火箭发射时的阻尼特性有着决定作用,而金属结构的材料阻尼特性对发射时的系统阻尼影响较小。The damping of multiple launch rocket system （MLRS） is key parameter of dynamic responses, which influences firing orders and firing interval. For typical structure of MLRS, typical factors of its damping characteristics were analyzed theoretically and the numeri- cal models based on multi-body dynamics method were simulated. The simulation results are consistent with theoretical analysis. The results show that friction in the joint between landing gear and rotary body, erecting cylinder damping and the deformation of flexible bodies are decisive factors of the damping characteristics, while material damping of the metal structure has little effect.
