Data for: single and multi-DOF planetary gear trains

The complete databases of non-fractionated planetary gear trains with 3-9 links and 1-3 DOFs are provided. Upper triangular elements (including the diagonal elements) of the adjacency matrix of each planetary gear train are stored in the database. The adjacency matrix of a planetary gear train is defined according to “Yang WJ, Ding HF, Zi B, et al. New graph representation for planetary gear trains. ASME J Mech Des 2018; 140(1): 012303”.本数据集提供了构件（links）数为3至9、自由度（degrees of freedom, DOFs）为1至3的非分体式行星齿轮传动系统的完整数据库。 数据库中存储了每个行星齿轮传动系统邻接矩阵（adjacency matrix）的上三角元素（含对角元素）。 行星齿轮传动系统的邻接矩阵依据以下文献定义：Yang WJ、Ding HF、Zi B 等. 行星齿轮传动系统的新型图表示法. 《ASME机械设计学报》, 2018, 140(1): 012303.
