摘要：

Stability analysis of a rotor system with the rotor disk placed in the middle of a massless shaft, having linear elasticity and internal damping, with linear elastic bearings at the ends and supported on viscoelastic supports, has been carried out. Stability zones have been determined for various parametric values, and results have been compared for cases with the supports being purely elastic or viscously damped and flexible. It is found that suitably chosen viscoelastic supports can increase the stability zones of the system considerably compared to the other types of supports considered. © 1992.
