Research on Bearing Dynamical Reaction of Micro Turboj et Engine Based on Rotor Unbalanced Quantity
摘要
Abstract
The unbalanced quantity of high-speed rotating micro turboj et engine in rotor system has espe-cially effects on working state of the rotor.On the premise that gyro is effective,the variations of bearing dynamical reaction in the micro turboj et engine with the rotating speed and unbalanced quantity distribu-tion azimuth angle are studied by using harmonic response analysis method.The results show that the greater the rotating speed is,the greater the bearing dynamical reaction,and the influence of the magni-tude of unbalanced quantity on bearing dynamical reaction is greater than that of rotating speed.The bear-ing dynamic reactions in the position of compressor and turbine are of maximum and minimum at unbal-anced quantity distribution azimuth angle of 180°respectively.The results of analysis provide an important reference for decreasing the vibration problem of engine and avoiding bearing damage caused by unbalanced quantity.关键词
