本刊曾于1975年2期,1979年1期分别介绍过摇床机构运动分析的图解,及富氏级数法,这对于难于找到运动方程的解析表达式S=f(α)的复杂机构,是十分有效的。本文介绍一种新的摇床机构,而且导出了运动方程的解析表达式。但由于函数关系复杂,直接求导计算速度曲线和加速度曲线函数表达式有一定困难,因而采用数值微分法借助计算机近似计算其速度曲线及加速度曲线。
This article was in 1975, 2, 1979, 1 were introduced kinematic analysis of shaker diagram, and Fu’s series method, which is difficult to find the equation of motion S = f (α) complex mechanism , Is very effective. This article describes a new shaker mechanism and derives analytical expressions for the equations of motion. However, due to the complicated function, it is difficult to derive the calculated velocity curve and the acceleration curve function directly. Therefore, the numerical differential method is used to calculate the velocity curve and the acceleration curve by computer approximation.
