| 摘 要： | 本文研究一个各向同性支承、无质量的转轴携带一个刚性圆盘通过临界速度时的非定常振动。根据系统的非线性特征,采用KBM 渐近方法得到一阶微分方程组,求得数值积分解。文中讨论了转子的陀螺效应对瞬态响应的影响,以及内阻尼对系统稳定性的影响。问题分理想能源(即常角加速度)和有限能源(即变角加速度)两种情况讨论。

| Abstract: | This paper studies the unsteady state vibration of a massless rotating shaft with
a rigid disk on isotropic supports on passing through critical speed.According to the
non-linear characteristics of the system,the KBM method is used to derive a first
order differential equation system capable of numerical integral solution.
The influence of gyroscopic effect of the rotor on transient response and that of
internal damping on the system's stability are discussed.The problem is examined
through ideal energy supply(which means constant angular acceleration)and limited
energy supply(which implies variable angular acceleration). |
