摘　　要：对带有预定时标齿轮四杆刚体导引机构生成进行了数学描述。分析了齿轮四杆机构连架杆摆角算子与连杆转角的内在联系 ,建立了包含 4 16 0 1组机构基本尺寸型的连架杆摆角算子数值图谱 ,推导出确定机构实际尺寸、连杆上标线的位置及安装尺寸等参数的计算公式。在此基础上 ,利用模糊识别方法进行刚体导引机构的尺度综合。运用该方法可以得到多个不同的机构方案 。Mathematic description of generation of rigid body geared four bar guidance linkage with prescribed timing is given. The inherent relation between side link swing angle operator and coupler rotation angle is analyzed. A numerical atlas of the side link swing angle operator consisting of 41601 dimensional types is set up. The mathematic equations for calculating actual dimensions of mechanism, coupler′s point position and dimensions of installation are derived. Based on solving these problems, the rigid body guidance linkage is generated by using fuzzy identification. Many different linkages can be achieved using this method, and an example is given to show sufficiently that the method is efficient and feasible.
