摘要：Based on an elastic rub-impact model, a dynamic model of a rubbing rotor system with an initial deflection was set up and motion equations were derived and solved numerically. Poincare maps, rotor orbits and bifurcation diagrams were drawn to investigate the effects of the initial deflection distance and the initial deflection angle on the vibration features of the rub-impact rotor system. The paper concluded that the initial deflection had great influence on the motion forms of the rubbing rotor system.
