摘要
Abstract
Vibration is a key problem of gas turbine systems. The vibration sources are complicated and various because of the complex structure of gas turbines. Study of vibration transferred to the turbine's supports is also an interesting topic for marine gas turbines. In this paper, the typical vibration excitation sources and their features of rotor systems of the turbines are analyzed and summarized. The excitation force transferred to the turbine's supports is analyzed. Through the computation of force transmission rate, the characteristics of vibration transform from the typical excitation sources to the supports are detected. The effects of bearing parameters and force action points on force transmission rate are discussed. And the frequency characteristics of the fluid force acting on the rotor system are also discussed. This research has guiding significance for vibration and noise reduction of gas turbines.关键词
