摘要
以8NVD48A-2U中速柴油机为例介绍了船用中速柴油机振动监测与诊断的试验研究，对柴油机振动激励源及振动特征量与磨损状态之间的关系进行了分析。研究表明，利用表面振动监测柴油机零部件的配合状态是可行的。
The fault diagnosis in matine medium speed diesel engine by using vibration signal is investigated.The properties of engine exciting forcesand the relationship betwteen the characterishc of vibhaon signal and the conditions of engine components is discussed.The investigating results show that it is feasible to moniter the working conditions of engine components by using vibration signal.
