Abstract

Abstract

A symplectic numerical method using the finite element algorithm in time scheme was proposed for rotor dynamics involving nonlinear factors, in which the Euler angle representation was introduced into the dynamic rotor system for the description of the nonlinear motion of rotation. The swirling motion of the rotor system including the beam-disc combination was analyzed. The numerical results demonstrate the validity and correctness of the proposed method, which can be used for the analysis of swirling motion of rotor systems in various situations.
