Torsional Vibration of Three Cylinder Engine with Balancing Shaft
Jurík, Juraj ; Hrdlička, Zdeněk (referee) ; Dundálek, Radim (advisor)
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.

Strength Analysis of V12 Cranktrain
Melounek, Michal ; Maršálek, Ondřej (referee) ; Novotný, Pavel (advisor)
This diploma thesis .deals with a crankshaft analysis of the VW 6,0 W12 engine. The first goal is to create a CAD model from the real part, then to create a FEM model for computer simulations. With respect to a dynamic character of the loading, the crankshaft is then reduced into a MNF file for the purpose of dynamic simulations in the MBS ADAMS/Engine. The full range of working RPMs is simulated in it. Beside the crankshaft the main and pin bearings are studied too. At the last part of this thesis the durability of the crankshaft is solved.
