The vibration characteristics of a marine diesel engine are important in optimizing its design for reducing the vibration and diagnosing the faults caused by it. In this study, we propose an appropriate simulation model by using the vibration data from vibration sensors and a 4190 ZLC marine diesel engine. The finite element model (FEM) was used for calculations that were verified by the modal test. The results showed that the fourth to sixth orders of the vibration frequencies simulated by the FEM were consistent with the measured ones within a difference of 5%. The results verified that the simulation model provides a theoretical basis for improving the diesel engine structure and optimizing the design to reduce its vibration, which will contribute to preventing damage from resonance and enhancing reliability.
