Abstract

Unsymmetrical rotor is a type of rotor widely used in engineering, which has different characteristic from symmetrical rotor and is less stable especially. With application to finite element method and Newmark-β method, dynamic characteristic of symmetrical rotor and three types of unsymmetrical rotor are investigated. The numerical and experimental results show that, in the same boundary conditions, speeds of oil whirl and whip are decreasing with the increase of stiffness asymmetry, and become less stable.
