| Abstract: | This paper presents the vibration diagnosis research method for diesel engine main bearing shell abnormal wear condition.Two characteristic parameters,g_(max) and E_(high)/E_(total),to be used to monitor and diagnose diesel engine main bearing shell abnormal wear condition are proposed here.The real detecting result shows that it is feasible to use the engine surface vibration signal to diagnose main bearing shell abnormal wear trouble. |
