Abstract

On the basis of the dynamic equations of rotor system with pedestal looseness, rub impact and crack, the random response method of rotor system with pedestal looseness is researched. The method is based on stochastic perturbation theory and the Kronecker algebra, matrix calculus and random perturbation are used. the reliability of rubbing for the coupling fault of rotor system was studied by Applying stress-strength interference theory and fourth-order moment technology, and on the basis of reliability analysis, the reliability sensitivity of rub impact on coupled fault rotor system is discussed by combining the sensitivity technology .
