末敏弹系统多刚体动力学分析与仿真

Multi-body Dynamics Analysis and Simulation of Target Sensitivity Drojectile

对末敏弹实体模型简化后,运用多刚体动力学中的R-W方法和牛顿-欧拉方法对末敏弹系统各刚体之间的力学关系进行了分析,建立了末敏弹运动的数学模型。编制程序对末敏弹数学模型进行了仿真分析计算,得到了伞弹系统开伞后的运动规律和敏感器扫描的规律,为系统设计提供依据。

The exterior ballistic characteristics of terminally sensitive submunition were analyzed in detail, firsty the model was simplified, the mechanical relation of the three rigid bodies which were friction plate, parachute and numiton was analyzed with the method of R-W mutti-bodies, mathematic model,the movement law of the umbrella ball system parachute-opening and the scan laws of sensitive implement are gained. They provide a basis for system designs.
