提出的新方法将阶梯轴分为若干段，每段可视为等截面轴，每段内所满足的扭振混合状态方程可精确地求出，然后利用两段之间的连续条件和边界条件将固有频率求出。
The proposed new method divides the stepped shaft into several sections, each of which can be regarded as the axis of equal section. The equation of the mixed state of torsional vibration in each section can be obtained accurately. Then, by using the continuous condition and the boundary condition The natural frequency is calculated.
