本研究以有限元素模型探讨固定轴向力矩对转子轴承系统动力学的影响。有限元运动方程的制定使用变分法和列入轴向扭矩产生增量扭转刚度矩阵。这个矩阵是循环的，因为系统是非保守的。有限元模型用于确定短轴承和长轴承的均匀轴的静态屈曲扭矩和临界转速。
This study investigates the effect of constant axial torque on the dynamics of rotorbearing systems using a finite element model. The finite element equation of motion is formulated using the variational approach and the inclusion of axial torques gives rise to an incremental torsional stiffness matrix. This matrix is circulatory since the system is non-conservative. The finite element model is used to determine the static buckling torques and the critical speeds of a uniform shaft for short and long bearings.
