摘　　要：末敏子弹稳态扫描阶段的运动特性对探测器的目标识别具有重要影响。为研究末敏子弹稳态扫描阶段的运动规律,采用第二类拉格朗日力学方法,建立伞-伞盘-弹体系统三刚体动力学模型,得出系统的动能和广义力,并将其带入拉格朗日方程进行求解,得到系统运动方程。使用Adams软件对伞-弹系统进行仿真,得到系统在稳态扫描阶段的运动特性,结果符合末敏子弹稳态扫描阶段运动的实际情况。Motion characteristic of terminal sensitive bullet in steady scanning stage has an important influence on target recognition of detector.In order to study the motion law of the final sensitive bullet in the steady scanning stage,using Lagrange mechanics of the second kind,three-rigid-body dynamic model of umbrella-umbrella disc-projectile body system was established,and the kinetic energy and generalized force of the system were deduced,and it was put into the Lagrange equation to get the equation of motion of the system.Adams software was used to simulate the umbrella-missile system,the ballistic characteristics of the system in the steady-state scanning stage are obtained.The simulation result was consistent with the actual situation of the motion of the final sensitive bullet in the steady-state scanning stage.
