Vibration measurement on large 2-stroke marine diesel engines is a very cost intensive and time consuming process. Each single measurement and optimization loop has large expenses as consequence. Therefore simulation plays an important role in the design process of such an engine. For the vibration assessment of the structure of Wärtsilä 2-stroke engines a simulation process was developed. In a first step a modal analysis is performed. Then the engine structure is loaded by the gas pressure resulting from the combustion process and by the inertial forces arising from the moving parts. A harmonic response simulation is carried out over the complete operation speed range of the engine. The resulting Campbell and order diagrams supply information about excited mode shapes, critical engine speed ranges, vibration amplitudes, etc. and allow optimizing the engine structure regarding minimization of vibrations. The complete simulation procedure is demonstrated on the example of a 2-stroke diesel engine which is destined for the propulsion of a cargo vessel. The obtained numerical results are then proven with measurement data.
