摘要

建立了盘式拉杆转子的耦合动力学键合图模型，刻画了盘式拉杆转子各部件之间在相互关联处的力学状态和性质，分析了各部件间的耦合关系的影响。同时运用该模型和简化的连续整体转子模型（将转子看成掏空拉杆后的连续整体转子）对实验盘式拉杆转子进行理论计算，由计算结果和实验结果对比分析表明该模型较连续整体转子模型精度有较大提高，并能较好地反映盘式拉杆转子的力学特性。

Abstract

A coupling dynamic model of disk rod fastening rotor is established by using bond graph in this paper. Coupling properties of the component parts of disk rod fastening rotor are depicted and its effects are analyzed. The natural frequencies of the disk rod fastening rotor are calculated by using the model presented here and by using the integral rotor model at the same time. The study shows that the calculative results of the model presented here are much closer to the experimental results than that of the calculative results of the integral rotor model.
