Four-cylinder gasoline engine with cylinder deactivation
Steigl, Vladimír ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this diploma thesis is design of configuration and balancing of crankshaft which is determined for four-cylinder gasoline engine. The thesis investigates kinematics, dynamics and possible ways of balancing the inertial forces and moments of the rotating and sliding parts of the central crank mechanism. Subsequently, the 3D CAD model is designed according to the presented drawing. It is transformed into a spare torsion system, from which the calculations of its own and forced torsional vibrations are based. The proposed 3D CAD model is then spatially transmitted in the FEA software Ansys Workbench and modified (boundary conditions, etc.) in the FEA software Ansys Mechanical APDL so that it can be calculated according to the selected LSA method. From the selected results of the LSA method, the crankshaft safety factor against fatigue damage is calculated.

Design of the testing station basis
Tichý, Jiří ; Růžička, Bronislav (referee) ; Prokeš, František (advisor)
The purpose of the Bachelor’s thesis is to design steel construction of the testing station basis for traction motors. For introduction to a topic there is an overview of current trends in testing stations at the thesis beginning. Final construction will be designed based on the analytical and numerical calculations. At the end the results will be analyzed.
