Abstract: Because of the effects of multi-physics, multi-scale and fluid-structure interaction(FSI), the vibration characteristics of the hydraulic pipeline system is not only complex, but also harmful. Due to the demand of the industrial production, the hydraulic system is gradually to develop in the direction of high pressure, high speed and high power ratio, which makes the production and propagation mechanism of hydraulic pipeline vibration become more complex. So it is necessary to summary and analyze the research status of the vibration mechanism and control method of hydraulic pipeline. Harmfulness and complexity of hydraulic pipeline vibration are expounded. Combined with the research on hydraulic pipeline vibration and dynamic model which the domestic and abroad experts are committed to in last ten years, hydraulic piping vibration mechanism, in which effects of multi-physics, multi-scale and FSI is taken into account, is summarized. On this basis, some research such as hydraulic pipeline of FSI linear dynamic model and nonlinear vibration model are analyzed, too. Research on vibration control method of hydraulic pipeline is also analyzed, such as active vibration control, passive vibration control and semi-active vibration control. The development tendency of FSI vibration mechanism and control of hydraulic pipeline are proposed.
