计算齿轮啮合刚度的matlab程序，非常有用的，希望大家积极下载(Matlab program for calculating gear mesh stiffness. It is very useful. I hope you can download them actively.)

采用Python语言开发的石川公式，计算齿轮对的时变啮合刚度。 函数设计良好，注释合理。(The ShiChun formula written in Python for gear pairs time-varying mesh stiffness calculation. The functions are well designed and commented.)
