空间交会对接过程的动力学模型与仿真

在空间交会对接过程中．从首次接触碰撞到完成捕获与捕获后的缓冲校正这两个阶段是对接动力学研究的重点。建立动力学模型进行仿真是研究的一个有效途径．以有内导向办异体同构周边式对接机构为研究对象．从机构的物理模型出发建立了对接捕获阶段与缓冲校正阶段的动力学模型。在动力学仿真软件DADS的接口上开发相应的用户模块．完成交会对接过程的动力学仿真．

Dynamical model and simulation of rendezvous and docking procedure

In the course of space docking, the process from the first contact to finishing the capture and buffering after the capture are the research focus of docking dynamics, and establishing the dynamical model and simulation is an effective way for the research. In this paper, in accordance with the docking mechanism of androgynous and peripheral type with inner guide petals, and based on the mechanism physical model, the dynamical models in docking capture process and buffering process were built, and some user-defined modules were developed using the interface of the famous software named DADS, which can accomplish the simulation of docking procedure.
