Anomalous Fractures of Diesel Engine Bearing Cap Bolts

According to the characteristics of large size, small clearance ratio, high oil film pressure and thin oil film thickness in the actual conditions of high power marine diesel engine bearing, this Paper analyzes oil film pressure distribution on inner surface of bearing bush based on the finite difference method, uses finite element method to establish the hierarchical model, and analyzes stress and strain distribution on bearing alloy. In addition, this Paper researches the changes of stress and strain distribution on bearing alloy layer when alloy layer thickness changes for the optimization design of high power marine diesel engine bearing bush.

Fretting fatigue becomes a typical failure mode for engine cylinder block caused by the increasing of the gas pressure and rotating speed, but the mechanism of fretting fatigue under diesel engine load condition hasn’t been systematic studied. In this paper, the fretting behaviors are mainly discussed by using fretting friction work parameter W and crack initiation location parameter G.

This paper reviews the monitoring diagnostic methods for the sliding main engine bearing wear. Those methods by oil, temperature, vibration, strain and other surveillance means are in more engineering applications. Moreover, this paper expounds a kind of new diagnostic method for main bearing wear monitoring - the thermoelectric power monitoring method.
