Torsional Vibration of Three Cylinder Engine with Balancing Shaft

Content of this master thesis is analysis of torsional vibration of the three cylinder engine with balancing shaft. In theoretical part of the thesis the kinematic and dynamic description of the cranktrain mechanism is included. The formation of unbalancing of the engine and methods of balancing are described in the theoretical part as well. In practical part of the thesis the analytical calculation of torsional vibration is provided. Simulation of the engine model in multibody software Adams/Engine was used as the other way of torsional vibration analysis. In the result part of the thesis the comparison of the both way of analysis were discussed. Last step of the thesis was design proposal of the torsional vibration damper done by the analytical calculation
