摘　　要：以辅助圆为基础,引入辅助设计长度l,角度(?),利用给定条件与设计杆长之间的几何关系经推导得出:(1)图解法设计-借助l或(?)直接确定辅助圆上固定铰链中心A点,以得到满足给定条件的机构;依据l还能解决平面四杆机构其他方面的设计问题。(2)解析法设计-曲柄长α和机架长d的计算公式。Using the auxiliary circle, introducing auxiliary design length l, angle (?) , using definite condition and design length, we can calculate and arrange: (1) Design of graphic method - with the help of lor (?), we can immediate define point A on the auxiliary circle for the fixed hinge center,and we can get the define condition mechanism; using l we can settle the other design methods for the planar four - bar linkages.(2) Analytic design method - calculating formula of crank length 'α' and rack length 'd'.
