This thesis deals with the design of a crankshaft for a high power racing engine using modern technology. It covers all of the steps from a brief research, design, torsional vibration analysis to fatigue calculation using FEA and MBS models.

Design of a rubber damper for 4-cylinder in-line CI-engine is this aim of this thesis diploma. Thesis consists from several parts. First part describes technical solutions of dampers of torsional vibrations. Second part contains torsional vibrations analysis of crankshaft without damper. The last part of this thesis describes design of rubber damper and torsional vibrations analysis of crankshaft with damper.

The purpose of this thesis is design of a six-cylinder engine arrangement with given main parameters (bore, stroke, etc.), powertrain design, possibilities of firing order, balancing inertia forces and its moments, in case of need, balancing shaft design and calculation of torsion vibrations.

The diploma thesis deals with a calculation and a construction concept of a balancing unit of a strait five cylinder combustion engine. The thesis contains the calculation and the construction concept of the balancing shafts. Also the concept of the calculation model of a driving mechanism with the balancing unit in MSC Adams – Engine is included.

The main subject of this dissertation is a comparison between different methods of controlling the output in compression and spark ignition engines in light of economic- ecological parameters, effects on engine functioning as well as vibrations. Main types of power control, their principle, advantages and disadvantages are presented in the text. There are several comparative simulations described and presented at the end of this work that were created by using a multi-body system. Calculation of parameters and simulations were selected to approximate resulting values to real values as much as possible.

The purpose of this thesis is design of a crank mechanism for diesel aircraft engine. Next then appropriately balance crank mechanism, strength tests and calculation of crankshaft torsional vibration. Developing of drawings documentation of crankshaft.

This thesis describes the variety and the width of issues connected with crankshafts of combustion engines. It distinguishes different factors, which influence the shape and size of these crankshafts and the selected findings are then transferred into the design of crankshaft for the particular engine. The thesis also presents coherent description of application of topology optimization to the particular crankshaft and also different, more complex design procedures leading to the optimal shape of crankshaft are afterwards suggested. Quality of such a design is then verified by comparative analysis of fatigue of the crankshaft.

The purpose of this thesis is the design of a radial spark-ignition engine in two layout variations, the stress analysis of selected components using the finite element method, the eventual optimization of selected components and the determination of safety on their most strained locations.

The aim of this work is to propose a cranktrain of a petrol six-cylinder aircraft engine with the specified parameters. Build dynamic model involved an air reducer and carry out the life-stress analysis important key parts of the crankshaft.

The purpose of this thesis is determinate the forces in crankshaft mechanism acting on new design engine from company Zetor, assessment of the state of balance, design modifications balancing units, calculation of modal analysis, stress analysis and strain control. The content of the work is the creation of technical documentation for the newly modified balancer shafts.
