Abstract

To avoid harmful and even catastrophic influences on internal combustion engine-generator set, it is essential to investigate early faults such as misalignment, rotor rubbing, shaft cracks, and bearing faults. To study the effect of the misalignment of the elastic coupling on vibration characteristics of the rotor system, experiment with different misalignment amplitudes and types is carried out on a flywheel-elastic coupling rotor test rig. Vibration responses of the rotor system with different amplitudes of parallel and angular misalignment are illustrated by amplitude frequency response curves, orbit plots and frequency spectra. Super-harmonic resonance phenomenon is revealed. Based on the misalignment of the high elastic coupling, dynamical equations of a generator rotor system, excited also by unbalanced magnetic pull and mass unbalance, are derived using the energy method and numerically investigated by the Runge-Kutta method. The theoretical results are in good accordance with the experimental ones. Besides, a new phenomenon of the flywheel-elastic coupling vibration system is found in the experiment.
存在不对中故障的旋转飞轮-弹性联轴器系统的振动特性:实验与模拟
为了避免对内燃机-发电机组造成有害甚至灾难性的影响,有必要对早期故障(如不对中、转子摩擦、轴裂纹和轴承故障)进行调查。为了研究弹性联轴器不对中对转子系统振动特性的影响,在飞轮-弹性联轴器转子试验台架上进行了不同不对中幅度和类型的试验。通过振幅频率响应曲线、轨道图和频谱图说明了不同平行和角度不对中振幅下转子系统的振动响应。显示了超谐波共振现象。基于高弹性耦合的不对中,使用能量法推导出了发电机转子系统的动力学方程,该方程也受到不平衡磁拉力和质量不平衡的激励,并使用 Runge-Kutta 方法进行了数值研究。理论结果与实验结果十分吻合。此外,实验还发现了飞轮-弹性耦合振动系统的新现象。
