摘要
针对Jeffcott转子,采用修正的双控体密封模型,建立转子—密封系统模型。进行模型简化得到系统的状态方程,改进双控制体模型并利用连续性方程和动量方程得到其控制方程;将所得的系统状态方程和控制方程结合,研究转子—密封系统的振动动特征,分析转子的非线性振动现象。
A model of a rotor- seal system of the Jeffcott rotor based on improved double- control volume model was proposed. The Jeffcott rotor model was simplified and the state equation of the system was obtained. The double-control volume model was improved so that the control equations of the system were obtained according to the continuity and momentum equations. The vibration characteristics of the rotor- seal system were investigated by combining the state equation with the control equations, and the nonlinear vibration phenomena of the rotor-seal system were analyzed.
