摘　　要：在纸机设备维护中,由于工艺条件的改变,设备运行状况的劣化等因素,设备在运行过程中会产生共振的现象。一旦设备发生共振,将激起设备剧烈的振动,并有可能在短时间内造成设备的失效。而往往受限于测量仪器、生产条件等因素的制约,对于设备因共振所产生的故障难以准确地判断。本文以长网纸机顶网共振的实际案例为例,说明共振产生的机理,以及如何在现场对设备的共振故障进行诊断,并采取相应的应对措施。In the maintenance of paper machine,resonance also happens in the equipment due to production condition,equipment running and etc.It can lead to the equipment failure in a short time.However,limited by the instrument,production condition and etc.,technician cannot diagnosis the resonance fault.Taking the resonance of top wire as an example,this paper will illustrate the principle of resonance,how to diagnose the fault of resonance in site,and the solutions.
