Connecting rod of gas V-sixteen engine
Laštovica, Karel ; Ramík, Pavel (referee) ; Píštěk, Václav (advisor)
This diploma thesis deals with a design of a stationary engine connecting rod, its stress analysis and its safety factors. The thesis is divided into several parts. At the beginning there is a short research of connecting rods construction and a description of the engine. Then the main dimensions of a piston group and a connecting rod are defined and its 3D model is created. Next, the calculations of forces acting on the connecting rod in the crankshaft mechanism, are carried out. The following part deals with a stress analysis of the model created by MPK. From the obtained stress results, the safety factor at fatigue limit in chosen places of the connecting rod is calculated. In the conclusion, the results of the stress analysis and set safety factor level, are recapitulated.

Con Rod design and optimization of racing engine
Ulman, Jaroslav ; Zháňal, Lubor (referee) ; Beran, Martin (advisor)
This master thesis describes the design and optimization of connecting rod motor racing car. At the beginning of the whole work is a 3D-model of rods, from which then the whole work is based. Then it analyzes the current model of stress and on the basis of the results are made structural changes to the solution of rods. Newly adapted connecting rod is again analyzed using FEM and newly obtained results are compared with results of the original model of connecting rods. The conclusion deals with sensitivity analysis of selected parameters of rods and their potential effect on the resulting changes in strength connecting rod .Then is an assessment of all results.

Mechanism of a one-cylinder spark ignition engine with elongated expansion
Tokař, Stanislav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis concentrates on the design of crank-type mechanism of engine with elongated expansion. The main attention is paid to examination of the progress of kinematic quantities and inertial forces in mechanism. Further on in the thesis, the analysis of piston-rod stress is carried out and is compared to the piston-rod of standard engine. In the last part of the thesis, there is an evaluation of advantages and disadvantages of the proposed mechanism solution.

Stress and strain analysis of connecting rod in combustion engine using FEM
Biječek, Tomáš ; Hutař, Pavel (referee) ; Vaverka, Michal (advisor)
In this diploma thesis is completed the FEM analysis of connecting rod in combustion engine Briggs & Stratton of the garden lawnmower. Within the frame of computing in the FEM system ANSYS Workbench is solved static structural strein and stress analysis, buckling analysis a fatigue also. The boundary conditions for FEM computing come out from the kinematic and dynamic analysis of the crank-slider mechanism in combustion engine. The 3-D models of the crank-slider mechanism are created in parametric SolidWorks modeller. Own construction variants of the connecting rod based on results of FEM analysis are also designed.

Mass Reduction of 4-cylinder In-line CI-engine Con-rod
Zatloukal, Lukáš ; Ramík, Pavel (referee) ; Novotný, Pavel (advisor)
This diploma thesis applies to the light-weight itself of a connecting rod of a mass-produced tractor-engine. As a one of the most important and first part of this task is creating a 3D simulation model of a connecting rod. The strenght calculation is following skip factor of the light-weight, the exact calculated dimension of relieve is providing by means of an engine imbalance including the connecting rod. The outcome data of research are instrumental to the new relieve and strengthen 3D design. The conclusion and ending point of the diploma thesis evaluate results.

Piston and Connecting Rod Assemblies of a SI Engine
Adam, Petr ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This bachelor's thesis is focused on the design piston and connecting rod set, where was chosen for design the six-cylinder four-stroke spark-ignition engine. In design is going from existing engine, where are designed all parts of piston and connecting rod set on base of it. Subsequently is constructed mathematical model of kinematic and dynamics. Finally is going from dynamic for execution of strength control.

Piston group of a one-cylinder gasoline engine
Lux, Josef ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis deals with a piston set of the internal combustion engine. The main goal is to perform strength check analysis of the internal combustion engine piston set using analytical methods of elasticity and strength. Cultivator PF-62 was chosen to determine the basic parameters of the crankshaft mechanism and plot the force distribution. Results of the strength check analysis are evaluated in the final part of this thesis.

Formula 1 Engines
Kaňa, Roman ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
This bachelor thesis describes construction of some functional parts of the Formula 1 engine. In the first part I focused on crankshafts, connecting rods, pistons, valve gears and compared them with serial produced engines. The work further continues with the introduction of some unconventional solutions used on Formula 1 engines and comparison of the characteristics of known power units.
