| 摘 要： | 主自由度的选取对子结构分析准确程度起到了决定性的作用，其缩减质量矩阵以及分析结果的准确程度将取决于主自由度的数量和分布情况。为了研究子结构分析中主自由度的选取方法，以转向架构架为例提出了选取主自由度的一些方法准则。通过实例计算分析表明，所提出的主自由度选取方法是行之有效的。

| Abstract: | Choosing master degree of freedom(DOF) is a critical step in substructure analysis,and the accuracies of the reduced mass matrix and the solution depend on the number and location of masters. In order to research on the selection method of master DOF in substructure analysis,several guidelines for selecting master DOF are presented and a bogie frame is taken as an example. The calculation and the analysis illustrate that the selection methods presented are feasible and effective. |
