The influence of a computational model of crank train dynamics on engine block load
Charvát, Adam ; Dlugoš, Jozef (referee) ; Drápal, Lubomír (advisor)
This work investigates the influence of the computational model of the cranktrain dynamics on the engine block load around the main bearings depending on the discretization level of the bodies used. Four variants of the computational model of the cranktrain in the Multi-Body System software SIMDRIVE 3D are compared with respect to the load on the main bearings. Based on the obtained loads, a strength analysis of the EA211 series 1,5 MPI mass-production engine block, manufactured by ŠKODA AUTO, is performed, including the influence of pre-stress during the assembly of the cylinder head and bearing caps. To evaluate the results, a fatigue life calculation is performed, and the endurance safety factors in the grooves on the bottom of the engine block are compared.

Crank train of a two-stroke automotive engine
Štrba, Matej ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
The subject of this diploma thesis is the analysis and comparison of three-cylinder two-stroke engines with a displacement of 1000 cm3 of the Wartburg 353. The introduction of the thesis is a research that discusses the history of car production and development in Eisenach during the second half of the 20th century. The main subject of research is the engine, to which the vast majority of work is devoted. Using the available simulation tools, the cylinder pressure indication is determined, the crankshaft of the two engine variants is subjected to balance analysis, dynamic analysis in terms of torsional vibrations and bearing load is performed using the MBS method, then the two variants are compared.
