Analysis of Vibration Characteristics of Diesel Engine Based on Multi-body Dynamic Model
In order to reduce the torsional vibration of the crankshaft system,a three-dimensional model of the crankshaft system composed of piston,connecting rod,crankshaft,flywheel and silicon oil damper is established.Using the multi-body dynamics simulation software ADAMS,a multi-body dynamic model com-posed of a rigid hybrid engine system is established,which simulates the torsional vibration response and an-alyzes the torsional vibration of the crankshaft.The simulation results have high accuracy,and the calculation method has some engineering applications.
