【摘要】 为满足超大型(公里级)空间结构在轨组装的需求,设计了一种全新的空间大型结构体组装接口并对其装配性能进行了详细的分析。首先,详细设计了一种纯机械式双锁定组装接口。其次,通过建立接口运动学模型,对组装接口的容差性能进行了分析,得出X方向容差为14.25 mm,Z方向容差为15.84 mm,绕X,Y,Z三个轴的角度容差分别为5.65°、5.51°和5.34°。最后,对对接接口进行了ADAMS仿真分析,验证了容差分析的正确性,得到了对接机构接触力与静摩擦系数、机械臂推力、碰撞锥角之间的非线性影响关系,为空间对接机构的设计奠定了基础。更多还原

【Abstract】 To meet the needs of on-orbit assembly of super large(kilometer level) space structures, a brand-new assembly interface for large space structures is designed and its assembly performance is analyzed in detail. Firstly, a pure mechanical double lock assembly interface is designed in detail. Secondly, the interface kinematics model is established to analyze the tolerance performance of the assembly interface. The results show that the X-direction tolerance is 14.25 mm, the Z-direction tolerance is 15.84 mm, the angular tolerances around the X, Y and Z axes are 5.65°, 5.51°and 5.34°respectively. Finally, the docking interface is simulated by ADAMS to verify the correctness of the tolerance analysis. The nonlinear relationships among the contact force, the static friction coefficient, the thrust of the manipulator and the impact cone angle are obtained. The results lay a foundation for the design of a space docking mechanism.更多还原
