The Development And Exploitation On Experiment Rig Of High Speed Dynamic Balance

The value of rotor oscillation is one of signs judging the running stage of rotary machine. Unbalanced force, which is generated by rotating mass unbalance rotor acts on the mechanical bearing, and it is, represented though vibration. The effect of the balance is to reduce the bending of the rotor, decrease the vibration of the unit, and diminish the reaction of the bearings and the base of the unit. So the unit can be guaranteed operating safely and reliably. With the development of high parameters and large capacity unit, the smaller of unit oscillation is the better.In the paper, series of work has been done to research and develop high-speed balancing experiment rig. Some viewpoints and technical program were put forward to solve the problem; the feasibility was certified via modification and test of equipment.
