摘　　要：确定接触点问题是航天器对接过程中接近与接触阶段的仿真的关键问题。以内导向瓣异体同构周边式对接机构为例，给出了确定接触点的方法，建立了确定接触点的数学模型、接近与接触阶段两航天器的刚体运动方程，并对接近与接触阶段进行了数值仿真。仿真结果表明：所建立的数学模型和动力学方程是正确的。One of the key problems of two spacecraft's docking simulation in the period from approach to first contact is to determinate the contact points. In this paper, in accordance with the docking mechanism of androgynous and peripheral type with guide petals, the method to determine the contact point is given. The mathematical models of contact points and the equations of rigid body motion of two spacecraft's in the approach and contact period are established. The numerical simulation in this period are studied, all above work provides research bases for the simulation in the other docking periods.
