| 摘 要： | 用阻抗匹配法提出了转子-油膜-轴承-基础-土壤系统稳定性计算的理论方法,并计算了郑州机械研究所油膜振荡实验台的稳定性,计算结果与该所的实测值较吻合。同时,探讨了考虑基础-土壤影响之后失稳转速提高的原因与基础参数对系统稳定性的影响。

| Abstract: | To analyze theoretically the stability of a rotor/oil film/bearing/foundation /soil system,impedance matching method is developed.The method is applied to calculate the stability of oil film oscillation test stand in Zhengzhou Mechanical Engineering Institute,China.The results are proved in good agreement with those measured.The reason why an increasingly unstable speed occurs if taking the influences of foundation/soil into account is discussed,as well as the influence of foundation parameters on the system's stability. |
