摘要: The internal, combinational and sub-harmonic resonances of a simply supported rotating asymmetrical shaft with unequal mass moments inertia bending stiffness in the direction principal axes are simultaneously considered. excitation terms due to dynamic imbalances asymmetry. nonlinearities extensionality large amplitudes. To analyze nonlinear equations motion, method harmonic balance is utilized. influences inequality between two eccentricities corresponding external damping on steady-state responses bifurcation points investigated. numerical computations utilized verify results. results accordance those computations.
