本文分析了轴向力矩对连续转子临界转速的影响，转子的运动由一组包含横向剪切、转动惯量和陀螺力矩的偏微分方程描述。长轴承和短轴承的运动方程和相关边界条件以无量纲形式表示，以便于研究上述效应对扭矩传递转子临界转速的影响。本研究的结果进行了比较，经典的结果伯努利-进入和Eschlishenko，以确定转子的“二次现象”在临界转速计算的相对重要性。
An analytical investigation was made on the effect of axial torque on the critical speeds of a continuous rotor whose motion was described by a set of partial differential equations including the effects of transverse shear, rotatory inertia, and gyroscopic moments. The equations of motion and associated boundary conditions for long and short bearings were cast in nondimensional form to facilitate the study of the influence of the aforementioned effects on a torque-transmitting rotor’s critical speeds. The results of this study were compared to classical results of Bernoulli-Enter and Timoshenko to determine the relative importance of the rotor’s “secondary phenomena” in a critical speed calculation.
