简单连杆机构传动函数的傅里叶展开及其应用

Fourier expansion for the transmission function of the simple linkages and their application

本文研究了四种简单连杆机构传动函数的傅里叶展开，指出了机构尺度特征值对傅里叶系数的影响，从而为机构动力学研究提供了有力工具。

This paper studied the Fourier expansion of transmission function for four kinds of simple linkages and pointed out the influence of size characteristic value of mechanism upon the Fourier coefficient,thus provided a powerful tool for the study of mechanism kinetics.
