平面连杆机构的结构综合法,大多是以四杆机构的综合为基础,然后采用串联、并联、或叠联等手段加以扩充演化的方法。对于不是由四杆机构扩充而来的多杆机构的构型综合,目前还未见到一个普遍适用的简明易行的直接综合方法。对此,笔者从机构活动度出发,以机械网络图的简单环路数为设计参量,用结构关连矩阵求解,推导出一整套简易的公式,以便于各种平面连杆机构的 The structure of plane linkage mechanism synthesis method, mostly based on the synthesis of four-bar mechanism, and then use series, parallel, or overlapping means to expand the evolution method. There is currently no universally applicable concise and straightforward direct synthesis method for the synthesis of multi-bar mechanisms that are not extended by four-bar mechanisms. In this regard, the author starts from the activity of the institution, takes the simple loop number of the mechanical network diagram as the design parameter, and uses the structural relation matrix to solve it, and deduces a set of simple formulas to facilitate the design of various planar linkage mechanisms
