某无人机火箭助推发射段动态分析与仿真

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 three-dimensional solid and finite element models of UAV launching system and uses the explicit dynamics method to carry out the dynam-ics simulation of UAV finite element model. From the simulation results, the energy balance relation ship is satisfied and the UAV mo-tion characteristics meet its design requirements. This gives a certain reference to the UAV launching.
