本文提出了一种平面连杆机构新的综合方法——“最小圆心差法”。对于四连杆机构,综合分为两个步骤,可求得全部9个未知机构参数,即四连杆机构的全参数综合;对于六连杆机构,可求得13个未知机构参数。本方法不需要解非线性方程组,不需要使用通常的优化程序,设计点的数目多少不受限制,计算速度快,适于在微型计算机上计算,优化综合时无需事先给变量的初值。文中给出了几个算例并编制出了微型计算机的通用程序。 In this paper, a new integrated method of planar linkage mechanism is proposed - “minimum circle center difference method”. For the four-bar linkage, the synthesis is divided into two steps, all nine unknown parameters can be obtained, that is, the four-bar linkage full parameter synthesis; for six-bar linkage, you can get 13 unknown parameters. The method does not need to solve the nonlinear equations, does not need to use the usual optimization program, the number of design points is not limited, the computational speed is fast, and it is suitable for calculating on the microcomputer. The optimization does not need to be given the initial value of the variable in advance. In this paper, several examples are given and a general program of microcomputer is compiled.
