Abstract EN
A dynamic model of a double-disk rub-impact rotor-bearing system with rubbing fault is established.
The dynamic differential equation of the system is solved by combining the numerical integration method with MATLAB.
And the influence of rotor speed, disc eccentricity, and stator stiffness on the response of the rotor-bearing system is analyzed.
In the rotor system, the time history diagram, the axis locus diagram, the phase diagram, and the Poincaré section diagram in different rotational speeds are drawn.
The characteristics of the periodic motion, quasiperiodic motion, and chaotic motion of the system in a given speed range are described in detail.
The ways of the system entering and leaving chaos are revealed.
The transformation and evolution process of the periodic motion, quasiperiodic motion, and chaotic motion are also analyzed.
It shows that the rotor system enters chaos by the way of the period-doubling bifurcation.
With the increase of the eccentricity, the quasi-periodicity evolution is chaotic.
The quasiperiodic motion evolves into the periodic three motion phenomenon.
And the increase of the stator stiffness will reduce the chaotic motion period.
