Reduction of cranktrain mechanical losses
Lhota, Martin ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The aim of the bachelor thesis Reduction of cranktrain mechanical losses is to describe the issue of lowering mechanical losses occuring in the crank mechanism of internal-combustion engine. Therefore it aims to create a list of mechanical losses main sources, to show suitable methods to determine them, and to describe some of earlier used concepts leading to reduction of friction losses. Further, it is focused on the description and comparison of existing trends by which the given problem can be solved to a certain extent. The thesis also tries to evaluate these trends by an analysis following the standpoint of effectiveness and progressiveness, and to formulate a conclusion.

Formula Student Front Chassis Part Design
Lhota, Martin ; Svída, David (referee) ; Ramík, Pavel (advisor)
Martin Lhota Formula Student Front Chassis Part Design DW, IAE, 2011, 75 pp, 62 pics The aim of the thesis is to suggest a suitable configuration of Formula Student Car’s front part of a frame according to current rules of SAE organization in the Formula Student competition. In this proposal low weight, manufacturability and sufficient torsion rigidity were preferred, whereas previously suggested solutions were reflected. At first there is presented a list of important SAE rules for the construction of front part followed by a short recherché of development of the constructional solution of frames and frames suitable for Formula Students car. Secondly there is described process during frame construction design and its computational model for the analysis which simulates torsion with the support of MKP system. Gained results and some parameters of the frame are compared with similar version of the frame construction which was suggested and made for the first Formula Student Car of our University. Moreover, there is also presented summary of suggested frame and also recommendation with possible alternatives for the next development.
