In this paper, the rotating machinery at high speed is studied. there are discussed about numerical calculating methods for non - linear dynamical system, the rotor system radial impact and rubbing dynamics behavior analysis having the nonlinear rigidity on the unsteady and non - linear oil film, the rotor system dynamics behavior analysis with bending - torsional - pendular coupling vibrations, application of wavelet, fractal and network in fault diagnosis. the main works in this paper are as follows : ( 1 )
本文以高速旋轉機械為主要研究對象，系統、深入地研究了非線性動力學系統的數值計算方法、具有非線性剛度的轉子系統在非穩態非線性油膜力作用下的徑向碰摩動力學行為、轉子彎扭擺耦合振動的動力學分析、小波和分形理論及人工神經網路在故障診斷中的應用問題。 -
In the higher velocity, especially in the critical velocity, the continuous model is invalidity. 2, in this paper, assume that the track and wheels are ideally smooth and no carriage or wheel - axle bending vibrations occur. invoke the basic hypothesis of the bernoulli - euler theory of beams : namely, that plane cross - sections initially perpendicular to the axis during bending
2 、在對連續性模型的分析基礎上，假設軌道與車輪為理想光滑的、沒有車輛和輪軸激起的振動，引用bernoulli - euler梁理論的假設：即垂直於梁軸線的橫截面在彎曲過程中仍然垂直於梁的中性軸。 -
