摘要
在非火工甚低点式星箭解锁分离装置工作过程中,要求星箭分离在很短的时间内完成以及避免在星箭分离过程中产生较大的冲击力对其他重要的敏感元器件造成损害,因此在星箭解锁分离装置中摆臂旋转时间及由其与圆柱壳体碰撞产生的碰撞力对于整个分离过程的影响是不可忽略的。主要通过运用动力学及Herz接触理论对星箭解锁分离装置中一级摆臂、二级摆臂进行动力学建模及分析,运用数值分析软件对模型进行仿真计算,得出摆臂旋转时间和碰撞冲击力的仿真曲线,并通过实验验证理论模型的正确性;仿真分析结果与试验结果对比表明数据规律一致性较好,计算结果具有较高的可信度。
In the working process of the non-pyrotechnic and lower point-to-point impact satellite-rocket unlocking andseparation device,the swing arm rotation time and the impact force generated by the collision cannot be ignored for thewhole separation process.In this paper,the dynamics and Herz contact theory are used to the dynamic modeling andsimulation of the first and second stage swing arms in the separation device by means of the numerical analysis software.The simulation curves of the swing arm rotation time vs.impact force are obtained,and the correctness of the theoreticalmodel is verified by experiments.The mutual comparison between the simulation results and the experimental results showsthat the data consistency is good.The calculation results have a high reliability.
