摘要:

以弱撞击对接机构(LIDM)捕获系统的运动空间为研究对象,提出了影响运动空间的主要因素如驱动臂长度、转动副转角、结构框内径等对运动空间的限制。在此基础上,对捕获系统运动空间及其各截面进行了分析,并详细讨论了结构框内径对运动空间的影响,对LIDM的设计和优化具有重要意义。

Abstract:

The movement space of the LIDM’s capture system is studied in this paper. The main factors affecting the movement space including the arm length of actuator, the rotation angle of revolute pair, the inner diameter of structural frame, and so on are proposed. The movement space of the capture system and its cross sections are analyzed, and the influence of the framework’s internal diameter on the movement space is discussed in detail. The study is significant for designing and optimizing the LIDM.
