| Abstract: | With the dynamic equations developed for slowly variable mass rotor system and its shaft stiffness,damping,eccentricity and radial stiffness of stator taken as random parameters,the stochastic responses of the rotor system are studied systematically by means of matrix perturbation theory,Kronecker algebra,matrix differential calculus and theory of random vibration.According to the stress-strength interference model,a reliability model of slowly variable mass rotor system with rubbing is developed.The reliab... |
