摘要
为研究某无人机火箭助推发射起飞段的动力学特性,建立其动力学模型并进行了仿真;依据某无人机的真实结构和实际发射情况,建立无人机发射系统的三维实体模型,导入ADAMS中,并基于多刚体动力学方法对无人机仿真模型进行动力学仿真;通过仿真分析,得出了无人机平稳起飞的合适的火箭安装角和机体发射角,为无人机发射技术提供了一定的参考。
For the study of dynamic characteristics of certain Unmanned Aerial Vehicle （UAV） with boos- ting rocket in the launching take-off phase, a dynamic model of the UAV launching system is established and simulated. According to the real structure of the UAV and the actual emission situation, a three-di- mensional solid model of the UAV launching system is established, and then it is imported into the AD- AMS, also the multi-body dynamics method is adopted to carry out dynamic simulation analysis for UAV Simulation Model. From the analysis of the simulation results, it was obtained that there is a suitable rock- et installation angle and the emission angle of the UAV that can take off smoothly, which can provide refer- ences for UAV launching technology.
