高速气浮电主轴转子系统不平衡响应分析
Unbalance response analysis of high speed aerostatic motorized spindle rotor system
摘要
Abstract
According to the high speed of aerostatic motorized spindle,the complex dynamic behavior and the unbalance incentive,dynamical model is built up on the basis of Lagrange equation.And it is includes the differential equatioan of free vibration and forced vibration.Then,the residual unbalanced inertial centrifugal force and the mechanism of unbalanced magnetic pull are analyzed.Finally,a motorized spindle rotor-gas bearings system with the highest working speed of 250 000 r/min is simulated in the way of the unbalance excitation harmonic analysis.The dynamic behavior of high-speed aerostatic motorized spindle is revealed in supercritical mode at unbalance excitation.A theoretical basis is provided for the optimization design,vibration control to the rotor system of high-speed aerostatic motorized spindle in engineering application.关键词
