摘　　要：某厂8号机组大修后首次启动时前箱与1号、3号、4号瓦振动异常。通过对振动分析,确定造成该机异常振动的原因是共振和动静碰摩,为此分别采取提高升速率和热态动平衡等措施,消除了机组的异常振动,为同类故障的处理提供了依据。During first start-up after overhaul of No. 8 unit in one power plant, the abnormal vibration of front pedestal No. 1 ,No. 3 and No. 4 bearing occurred. Through analysis of the vibration, it＇s found that the cause of the abnormal vibration is resonance and impact- rubbing between movable and stationary parts. By raising the velocity rate and conducting thermal dynamic balance, the abnormal vibration is eliminated finally. It is useful for disposal of the same fault.
