平面机构自由度计算的两个问题

Two Questions about the Calculation of Plane-mechanism Movement's Number

本文论述了平面机构中局部自由度的识别和处理、复合铰链的重新定义和计算两个问题,为平面机构自由度的计算和机构的结构分析奠定了基础。

Two questions are concerned in this paper: the recognition and process of partial movement抯 number of the plane-mechanism; a new definition for the compound hinge and the calculation of its movement抯 number . By discussing the two questions, it lays the theoretical foundation for the plane-mechanism抯 calculation , and its construction .
