摘　　要：本文研究了用几段Ｂｅｚｉｅｒ曲线连接后构造凸轮从动件的修正等速运动规律中的类速度曲线的方法。研究结果表明，该方法不仅可以方便地调控出许多具有较好特性值的修正等速运动曲线，而且将其用于构造一般的运动曲线，也能得到较好的结果。本文向设计者提供了一个可按设计者的意图并借助于计算机屏幕图形显示对类速度曲线作直观调控的新方法。In the paper, the method of joining togetther some sections of Bezier curve to structure similar ve-locity curve of the modification constant velocity kinematic law has been studied, The research reeults showthat it is not only to get many kinematic curves of the modification constant velocity by regulation, whichhas good performance, but also can acquire good results if it is used in structuring common kinematiccurves.It provides a mew mothed that the designer can audio visually regulate similar velocity curve in ac-cordance with one s intention by the aid of CRT computer graphic display.
