本文通过原动件转换,给出原动件与转换构件角位移间的函数关系,再将其反函数用一多项式逼近。用机构有限个位置的角位移及其类速度值,通过求解线性方程组可确定此多项式的待定系数,从而提供了一种求解机构位置问题的新方法。该方法与现有的方法比较,当要求同时确定两个极限位置及多点位置时,比较简单,易于编制通用程序。
In this paper, through the conversion of prime mover, the function relationship between the prime mover and the angular displacement of the conversion member is given, and then the inverse function is approximated by a polynomial. Using the angular displacement of a finite number of institutions and their class velocity values, the undetermined coefficients of this polynomial can be determined by solving a system of linear equations, thus providing a new method for solving the mechanism position problem. Compared with the existing methods, this method is simpler and easier to program common programs when it is required to determine two extreme positions and multiple positions at the same time.
