The reliability of marine diesel engine under vibration and shock excitation is an important index to measure the performance of diesel engine. This paper conducts dynamic modeling and analysis for marine diesel engine system, introduces the vibration and shock excitation sources and characteristics of diesel engine in detail, and combines the energy acquisition sensor and embedded technology. A kind of shock fault monitoring system for marine diesel engine is established, and the performance test of the monitoring system is carried out by setting up the shock fault monitoring test platform.
