Dynamical simulation of marine diesel crankshaft system

Aiming at vibration analysis of marine diesel engine shaft systems and effects on hull structure,the dynamics model of rigid body in the marine diesel engine shaft systems of type 4160 were built by the software of SolidWorks and ADAMS.The motions and dynamics of crankshaft system were simulated based on virtual prototype,and the simulating curves of pistons motions,action force on the link and crank-pin were studied.The results indicate that simulation model conforms to its reality,and a new design method is given for further study of the diesel engine vibration.
