摘　　要：在空间交会对接过程中,从首次接触碰撞到完成捕获这一阶段称为对接捕获阶段,对对接捕获阶段动力学性态的研究是空间交会对接技术的关键,建立动力学模型进行仿真是研究的一个有效途径。以有内导向瓣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的三体力元模型。该模型考虑了缓冲系统六个方向之间的耦合和缓冲系统中齿轮等转动部件惯量的影响。并在动力学仿真软件DADS的接口上开发相应的用户模块,在DADS平台上完成对接过程的动力学仿真。In the course of space docking, the process from first contact to finishing capture is called docking capture process. Dynamics of the docking capture process is a key issue in space docking, which is often studied through numerical simulations by the dynamic modeling of the system. In this paper, the three-body force-element dynamic model of androgynous peripheral docking mechanism with inner guide petals is proposed. Coupling of six directions of buffer system and effect of rotating components such as gears in buffer system are considered in modeling. Then the corresponding user-defined modules in the interface of the software named DADS are developed. Numerical simulation is carried out by using the modules by using the DADS.
