摘要：Based on the established numerical lubrication simulation model of a main bearing of a certain type of diesel engine, combined with the orthogonal design method, the effects of engine speed, cylinder pressure, oil supply pressure and clearance on bearing lubrication characteristics are studied. The results of lubrication characters show that cylinder pressure and clearance are first and secondary factor of influence degree, oil supply pressure has the least impact, and the most effective way to improve bearing lubrication is to reduce the explosion pressure appropriately.
