| 摘 要： | 转子系统启动时的稳定性对设备的寿命和精度有着重要影响。针对现有研究方法求解过程复杂、结果不准确,采用ANSYS软件综合考虑陀螺效应分析了支撑刚度、支撑阻尼和启动时间对转子系统启动时稳定性的影响;并在数据有限的情况下,利用灰关联度分析方法对三者影响程度进行了研究。结果表明,在考虑陀螺效应影响下,随着支撑刚度、支撑阻尼和启动时间的增加,转子系统启动时的稳定性越来越好;三者的灰关联度系数均大于0.5,且数值相差不大,对转子系统的影响程度相当。

| Abstract: | The starting stability of rotor system has an important impact to equipment’s life and precision. To solving process of the existing methods were complex, the results were not accurate, ANSYS which consider gyroscopic effect was used to analyze the effect of support stiffness, damping and starting time on the rotor system. In the case of limited data, gray correlation theory was used to research the three influence degree. It is shown that with support stiffness, damping and starting time increased, the stating stability of the rotor system is getting better;their gray correlation coefficient are greater than 0.5, the value is similar, the influence of the rotor system is quite. |
