<正>采用一般的铰链四杆机构再现给定函数ψ=ψ(φ),由于受到精确点数的限制,精度不可能高。如再要求同一机构能实现不同的函数更是困难。本文探讨一种广义机构,可解决此间题。设计原理如下:

This article discusses and probs a method of a certain bar’s length in the Kinematic chain. The length will be changed automatically by the electrical control. Also this method can be applied to the function and path generation, or the position connecting rod.
