摘要
简述了小波变换的基本理论；给出了四杆机构输出函数的小波描述和小波分解的特性；利用Ｄａｕｂｅｃｈｉｅｓ正交小波对机构的输出函数进行了变换和分析，提出了机构输出函数小波特征参数的概念，为机构的函数尺寸综合时的参数识别提供了依据，最后给出了一个尺度综合的算例。
Based on the theory of wavelet transform, the wavelet description and wavelet decomposition properties about 4 bar linkage output function are deeply investigated in this paper. By the aid of Daubechies orthogonal wavelets, a new conception about 4 bar linkages output function, called the Wavelet Characteristic Parameters(WCP) is originated. All of this will provide a powerful tool for the output function parameter identification and function generating synthesis of the linkages. An example is also given in this paper.
