Abstract

The reasonable establishment of rotor dynamics model is very important in the study. This paper establishes a dynamic model of the rotor, and gets the numerical calculation of the frequencies and mode shapes of the rotor under the free condition. The modal of the rotor bearing system is analyzed by using software. Compared to the above two kinds of results, the test of turbocharger rotor mechanics correctly modeled is to prove that this method has practical significance.

机车涡轮增压器转子动力学模型验证方法研究
转子动力学模型的合理建立在研究中具有重要意义。建立了转子的动力学模型,对转子在自由状态下的频率和振型进行了数值计算。利用软件对转子轴承系统进行了模态分析。与上述两种结果相比,正确建模的涡轮增压器转子力学试验证明了该方法具有实际意义。
