Abstract

This study investigates the application of synchronous interaction dynamics methodology to the design of auxiliary bearing systems. The technique is applied to a flexible rotor system and comparisons are made between the behavior predicted by this analysis method and the observed simulation response characteristics. Of particular interest is the influence of coupled shaft/bearing vibration modes on rotordynamical behavior. Experimental studies are also performed to validate the simulation results and provide insight into the expected behavior of such a system.
柔性转子与辅助间隙轴承的相互作用动力学
研究了同步交互动力学方法在辅助轴承系统设计中的应用。将该技术应用于柔性转子系统,并将该分析方法预测的行为与观测到的仿真响应特性进行了比较。特别令人感兴趣的是轴/轴承耦合振动模式对转子动力学行为的影响。实验研究也进行了验证仿真结果,并提供洞察这样一个系统的预期行为。
