摘要
论述了具有陀螺效应的柔性转子在各向异性支承条件下回旋振动的特性,推导出了转子在正回旋激励作用下产生逆回旋振动的条件,提出转子振动存在逆回旋带的概念,并举例说明了转子在整个转速范围和振动频率范围内回旋振动的特点,作出了逆回旋带的曲线图。
In this paper the behaviour of a flexible rotor with gyroscopic effect on anisotropic supportsis discussed. The conditions for backward whirling of a rotor acted by a forward whirling force or momentare derived, the concept of backward whirling bands existing in rotor vibrations is proposed, and an exam-ple is given to explain the whirling vibration characteristic of a rotor within the whole speed and excitingfrequency range, the curves of backward whir1ing bands are drawm.
