Using Vibration Parameters for Wear Condition Diagnosis of Diesel's Main Sliding Bearings

In this paper, research work has been carried out on wear condition diagnosis of main sliding bearings used for a diesel engine, which includes fault simulation test for main bearing wear condition of the engine; measurement of vibration signals from main bearing saddle and engine base surfaces, and relavant parameters as well; analysis of vibration signals, as well as pick-up of characteristic perameters allowed for monitoring and diagnosing the main sliding bearing wear condition of diesel engines. The research has provided a feasible method for accurate diagnosis of main bearing wear condition in diesel engines.
