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。
In order to study the dynamics characteristics of a launching section of a rocket assisted by a rocket, the dynamic model is established and simulated. Based on the actual structure and actual launch situation of a UAV, a three-dimensional solid model of the UAV launch system is established , Introduced into ADAMS, and the dynamics simulation of UAV simulation model based on multi-body dynamics method; through simulation analysis, the appropriate rocket installation angle and body launch angle of UAV were obtained, Launch technology provides a reference.
