On the basis of the impact-rub dynamics equations of Jeffcott rotor-stator systems with imbalance
the reliability sensitivity investigation of rotor-stator systems of rotating machinery under impact-rub is presented.Techniques from Kronecker algebra
matrix calculus
fourth moment analysis
probabilistic perturbations
reliability theory and sensitivity technique are employed to systematically develop the mathematical and numerical expressions for reliability sensitivity analysis of rotor-stator systems.The effects of shaft stiffness and damping
stator stiffness and damping
radial clearance and stator radial stiffness on reliability sensitivity are studied and discussed.The numerical results are obtained.
