一类碰摩转子在弹性支撑下的分岔分析
Bifurcation Analysis of A Class of Friction Contact Rotors with Flexible Support
摘要
Abstract
Takeing the gravity factor as consideration,a rotor system with flexible support is analyzed in the paper,and it focuses primarily on studying the dynamics property of two degree-of-freedom,asymmetrically flexible supported rotors including clearances.According to the moving function of friction contact and no friction contact rotor,the stability of systems is explored.No friction contact rotors are studied via searching its resonance frequency.The threshold value of friction contact rotors are analyzed by bifurcation diagrams,Poincare sections map and time response figure.Finally,the deficiencies and improvements of rotor modeling are discussed.关键词
