| 摘 要： | 着重对一种弹-伞系统的动态特性进行了仿真计算。计算时，以刚体弹道代替传统的质点弹道，利用多体动力学方法作理论分析，在Solid Works和MSC．Aadms中建立系统的动力学模型，进而进行了弹-伞系统的动态特性仿真，主要是过载仿真计算。与理论计算比较，结果相近，证明了仿真计算的可靠性。

| Abstract: | In this paper, we mainly discuss the simulation calculation for dynamic characteristics of a bomb-parachute system. While working substituting, conventional particle ballistic with rigid body ballistic , we do theoretical analysis with multi-body dynamic method , set up kinetic model of the system in solid works and MSC. Adams, and make bomb-parachute dynamic simulation, in conducted. The result is near to theoretical calculation which the calculation of over-loading simulation is mainly conducted. The result is near to theoretical calculation , which proves the reliability of simulation. |
