Abstract: According to the theory of hydro-dynamic lubrication,and in view of transverse vibration of disk slice blade;a dynamic equation of high rotating disk slice blade system is established,which forms liquid press film by using high-rotating movement and transverse vibration,and restrains transverse vibration of the blade.High-rotating disk slice blade transverse vibration control and stability are studied by theory analysis and experiment.The result shows that liquid press film could effectively decrease swing value of blade trans- verse vibration,and the control effect of which correlates with the controller structure.
