| 摘 要： | 利用试验模态分析技术，在双跨三支承、多自由度柔性转子试验台上，试验研究了止推轴承及其间隙的改变对转子系统的稳定性的影响．通过对转子支承中不装止推轴承、装止推轴承且在两种轴向间隙状态下的三组试验的对照，证实止推轴承能有效地提高柔性多自由度转子系统稳定性．

| Abstract: | The influence of thrust bearings and the clearance within it on the stability of rotor system is investigated on the test of elastic rotor system with double spans, three bearings, and multiple degrees of freedom by means of experimental modal analysis technique. The tests without mounted thrust bearing and with the latter with two different axial clearances are conducted. By comparing the test results, it is concluded that the thrust bearings can effectively improve the stability of elastic rotor system with multiple degrees of freedom. |
