The squeeze film damper is usually adopted in the rotor system to suppress the vibrating motion of the rotor system. In this work, not only are the physical parameters of the squeeze film damper analyzed but also the system parameters, like the number of squeeze film dampers used and squeeze film damper implementation positions, are analyzed. The amplitude-frequency curves are obtained by conducting the simulation of a dual-rotor, intershaft, and oil film force concatenated model. Through the analysis and comparisons of the results, the vibration suppression effects of the squeeze film damper with different parameter configurations are analyzed and summarized. This work contributes to further optimization and dynamical analysis work on rotor systems with the application of the squeeze film damper.

应用压膜阻尼器的轴间双转子参数分析

转子系统中通常采用挤压油膜阻尼器来抑制转子系统的振动运动。在这项工作中，不仅分析了挤压油膜阻尼器的物理参数，而且还分析了系统参数，如使用的挤压油膜阻尼器的数量和挤压油膜阻尼器的实施位置。幅频曲线是通过对双转子、轴间和油膜力级联模型进行仿真得到的。通过对结果的分析比较，分析总结了不同参数配置下挤压油膜阻尼器的减振效果。这项工作有助于进一步优化和动态分析应用挤压油膜阻尼器的转子系统。
