Data for: Automatic synthesis of single and multi-degree-of-freedom planetary gear trains

The complete databases of non-fractionated planetary gear trains with 8-9 link and 1-3 DOFs are provided, as well as the databases of the corresponding parent graphs. For each parent graph, upper triangular elements of its adjacency matrix are stored. For each rotation graph or displacement graph of planetary gear train, upper triangular elements of its adjacency matrix, including the diagonal elements, are stored.

本数据集已提供连杆数为8至9、自由度（Degrees of Freedom, DOF）为1至3的完整非拆分式行星齿轮传动系统数据库，以及与之对应的母图数据库。针对每张母图，存储其邻接矩阵的上三角元素；针对该行星齿轮传动系统的每张旋转图与位移图，存储其邻接矩阵的上三角元素（包含对角元素）。
