本文对凸轮—连杆组合机构的设计提出了一种较为实用、简便的解析设计方法—称之为“单杆解析法”。只要给定了(或能够确定出)所要求的轨迹方程式y=f(x)和自变量x的定义域:x∈(x_o,x_m),以及确定了组合机构中各杆的长度,便可逐次应用单杆解析法直接建立起与给定轨迹m—m曲线上任一点i的座标(x_i,y_i)相对应的各个连架杆的角位移(如图1中曲柄OA的角位移φ_i)或线位移(如图1中的滑块d的位移X_D)之间的函数关系:φ_i=F_1(x_i,y_i),X_D=F_2(x_i,y_i)。
In this paper, a more practical and simple analytical design method is proposed for the design of cam-link combination mechanism - called “single-rod analytical method.” So long as the required trajectory equation y = f (x) and the domain of the argument x: x ∈ (x_o, x_m) are given (or can be determined) and the lengths of the rods in the combined mechanism are determined The single-bar analytical method is applied sequentially to directly establish the angular displacement (as shown in FIG. 1, the angular displacement φ_i of the crank OA) corresponding to the coordinate (x_i, y_i) at any point i on the m- Or displacement of the line (as shown in FIG. 1, the displacement of the slider d X): φ_i = F_1 (x_i, y_i), X_D = F_2 (x_i, y_i).
