Research has been done on the coupling form between the two-row planetary gear train and the shift restriction based on the matrix,and then the method of establishing mathematics model has been presented to analyze the planetary gear transmission using MATLAB.

在设计自动变速器时，总体结构方案主要由行星齿轮变速机构确定，因此，研究行星齿轮机构传动方案的结构特征，对其所有可能的方案进行分析，是理想的设计途径。

Research has been done on the coupling form between the two-row planetary gear train and the shift restriction based on the matrix, and then the method of establishing mathematics model has been presented to analyze the planetary gear transmission using MATLAB. The coupling-matrix, restriction-matrix and transmission matrix form the model. All coupling-matrices corresponding two kinds of the coupling form determine the planetary gear transmission model.

基于矩阵理论对双排行星齿轮变速机构的行星排之间联结、换挡约束进行研究，提出用联结矩阵、约束矩阵和传动矩阵构建数学模型并使用MATLAB进行传动分析的方法。2种方式的联结形式所对应的联结矩阵可以确定机构所有可能的结构型式，据此得到双排行星齿轮变速机构全部型式谱图。
