在轨释放、分离载荷动力学仿真研究

某些航天器需要在飞行过程中释放、分离载荷,由此涉及的动力学问题,关系到航天器平台与载荷的控制。文章主要对此类航天器的多体动力学问题进行研究,基于机械系统动力学仿真分析(ADAMS)软件平台建立了包括航天器平台、载荷和两类分离机构等在内的仿真模型,通过对三种在轨释放、分离载荷方案的分离过程动力学仿真结果对比分析以及参数化仿真分析,为载荷释放、分离方案设计提供参考。

Dynamics simulation of on-orbit release and separation of payload

Payload release/separation from spacecraft is usually required in space missions,and the related dynamic performance during the release/separation process is one of the important issues that would affect the control of the spacecraft platform and the payload.This paper focuses on the multi-body dynamics during separation/release,and uses the Automatic Dynamic Analysis of Mechanical System（ADAMS） software to establish the simulation model,including the spacecraft platform,the payload,and the separation mechanism,to simulate the process of on-orbit release/separation.The results can be applied in the design of payload release/separation.
