摘要
转子弯曲是导致转子振动量增大的重要故障源之一。首先分析各类转子弯曲原因,提出利用单平面主动平衡技术消除弯曲转子振动故障,并通过实验验证这种方法的可行性。实验结果表明,利用单平面主动平衡装置可将弯曲转子一阶临界转速处的振动峰值从550μm减小到100μm以下,降幅达到80%以上。可见应用单平面主动平衡技术,可以非常有效地控制由转子弯曲所引起的振动,具有良好的工程实用价值。
A rotor affected with bending is one of the major fault sources leading to an increase in vibration level of a rotor.The causes of the bending occurring on various kinds of rotor are first analyzed.Then,it is proposed to use single-plane active balancing techniques to eliminate the vibration fault of a bended rotor. Moreover,the feasibility of the proposed method is verified by tests.The results of the tests indicate that by using a single-plane active balancing device it is possible to reduce the vibration peak value of the bended rotor at a location of the first-order critical speed from 550 μm to below 100 μm,a reduction higher than 80%.From this example it can be seen that the technique under discussion can very effectively control the vibration caused by the bending of a rotor, demonstrating its high value in engineering practice.
