Partial Compensation of Unbalance by Oneand Two-Plane Automatic Balancing Devices

[摘要] This article presents an analysis of several aspects of one- and two-plane automatic balancing devices of rigid rotors. The effect of partial compensation of unbalance and the decreasing of vibrations in the region beyond the first criticalspeed is studied analytically and confirmed by the results of computer simulations. The possibility of partial unbalance compensation is very important considering application ofautobalancing devices to rotors with a large polar moment of inertia.Among the most important practical applications of devices are centrifuges, hand power tools, washing machines, and optical disk drives.
