基于拉格朗日方程的积油转子系统力学建模和数值仿真
Mechanical Modeling and Numerical Simulation of Oil Leakage Rotor System Based on the Lagrange Equation
摘要
Abstract
On account of the operation faults caused by the oil leakage in rotor cavity, to explore its dynamic characteristics, a double-support simplified rotor model has been proposed. In the model,leak oil is transformed into a concentrated mass oil-block. Then the dynamic equation is deduced by the Lagrange equation, based on the numerical simulation, vibration responses caused by the rotating speed are investigated. Result shows that frequency-locking phenomenon will appear when the rotating speed exceeds the first critical speed.关键词
