Automatic Balance of Rotating Machinery and Wholeness Dynamic Balance of Aeroengine

Abstract

AbstractOn the basis of studying the mechanism of same-frequency vibration failure, the causes of same-frequency vibration of rotating machinery are summarized into 26 kinds of 10 categories. The essence of automatic balance is that the automatic balance system traces the source, through the actuator to timely and appropriately adjust the mass distribution or directly to generate the rotation vector self-recovery force. The electromagnetic automatic balance system for supergravity machine and high-end machine tools are briefly introduced. The principle of a pneumatic liquid automatic balance is put forward. The principle and method of aero-engine wholeness balance are proposed and the automatic balance system for aeronautical propeller unbalanced coupled vibration is introduced.
