Abstract
The dynamics analytical model of crankshaft system Flexible Multi-Body of a 8—cylinder diesel considering hydrodynamic lubrication was established.Main excitations of dynamic properties analy-sis-reaction force of main bearing and reaction force of the piston thrust—of the block were found out by analysis.And the vibration response of this block was calculated under the action of these excitation forces.The vibration velocity of every panel point of block was obtained,and thus provided a foundation for the low noise design.
