Identification of a model of crank shaft with a damper of torsional vibrations

The paper presents modelling and the process of dynamic model identification of crankshaft system. At the beginning some information about design, operation and test of crankshaft systems is shown. The next section describes the process of crank-piston mechanism with a vibration damper modelling and the method of obtaining the motion equation. The last but one section demonstrates some aspects of the process of dynamic model identification. Moreover, tests and numerical simulation are presented. At the end, there is a summary of the whole paper. Conclusions about modelling and identification of dynamic model of crankshaft systems are shown
