Abstract

Abstract

The basic equation of transverse vibration for rotor systems was investigated. First the previous precise nonlinear mathematical model for rotor dynamics, which had been built through the introduction of the Euler angle representation to describe the nonlinear motions of rotors, was discussed. Then a linearized model for rotor dynamics based on the precise nonlinear mathematical model was developed. Results of the numerical tests verify the correctness and validity of the proposed linear basic equation.
- rotor dynamics,
- Euler angle,
