Complete databases of tree graphs and displacement graphs of 1-DOF planetary gear trains with 3 to 10 links

The complete databases of tree graphs and displacement graphs of 1-DOF planetary gear trains with 3 to 10 links are provided. For each tree graph or displacement graph, upper triangular elements of its adjacency matrix are stored in the database.本数据集提供了包含3至10个构件的单自由度（1-DOF）行星齿轮系（planetary gear trains）的树图（tree graph）与位移图（displacement graph）的完整数据库。针对每一幅树图或位移图，其邻接矩阵（adjacency matrix）的上三角元素均存储于该数据库中。
