摘　　要：为检验某无人机火箭助推发射装置的性能,建立无人机发射系统的三维实体模型及有限元模型,并基于显式动力学方法对无人机有限元模型进行动力学仿真。由仿真结果可知,能量平衡关系得到了满足,无人机运动特性均满足设计要求,为无人机的发射提供了一定的参考。In order to verify the boosting rocket performance of a unmanned aerial vehicle（ UAV）,this paper establishes the threedimensional solid and finite element models of UAV launching system and uses the explicit dynamics method to carry out the dynamics simulation of UAV finite element model. From the simulation results,the energy balance relation ship is satisfied and the UAV motion characteristics meet its design requirements. This gives a certain reference to the UAV launching.
