Welding of socket from C-Mn steel
Boček, Martin ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
Final thesis, elaborated within the master study in the field of Manufacturing technology, deals with analysis and solving of weld cracking problem in welds of anti-roll bar socket for passenger car. Sockets material is fine-grained low-alloy steel S420MC. For better understanding of the problem, a literary study has been elaborated, describing the issue. Next, an analysis of parts material and its weldability, has been conducted, according to ČSN EN 1011-2 standard. After an analysis of cracks and considering current conditions of sockets welding a series of experiments has been designed to evaluate impact of different process parameters on final weld quality. Experiments results have been used to compile a series of recommendations for adjustment of the welding process and to eliminate weld cracking. The results of the experiments were used as a basis for elaboration of WPS protocol.
Measurement of torsion bars and stabilizers
Bláha, David ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis deals with the measurement of the anti-roll bar characteristics. The target of this thesis is to design a device for measuring of torsional stiffness of the automobile stabilizer bars, design a measuring sequence for detection values subsequently used to calculate the stiffness, and calculate the total measuring error. The measuring device is designed for the needs of the Institute of Automotive Engineering of FME BUT.
Design of vehicle suspension stabilizer
Macháček, Tomáš ; Ramík, Pavel (referee) ; Porteš, Petr (advisor)
Tato diplomová práce je zaměřená na stabilizátory u podvozku aut. První část popisuje všeobecné znalosti vlivu naklonění karosérie na jizdní vlastnosti auta a možnosti konstrukčních řešení používaných v praxi. Dále jsou v této části uvedeny nevýhody použití stabilizátoru a jejich náhrady. Nasledující téma se zaměřuje na soutěž Formule Student a její všeobecná pravidla. Hlavní částí této práce je analýza stabilizátoru Formule Ford, na kterou v poslední části této práce navazuje analýza předního a zadního stabilizátoru Formule Student. Byly vytvořené kompletní MBS modely pro přední a zadní zavěšení včetně stabilizátoru. Díky těmto modelům bylo možné provést výpočty klopných tuhostí a pevnostní výpočty. Z těchto výpočtů bylo možné určit vhodné nastavení stabilizátoru. Všechny modely mohou být dále použitelné pro analýzu jízdních vlastností příslušného vozidla.
Design of vehicle suspension stabilizer
Krasula, Jan ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
This master’s thesis is focused on a design of the formula student’s anti-roll bar. The beginning of the thesis is devoted to the introduction of the anti-roll bar function and the explanation of its effect on a vehicle including the analysis of various constructions. Second part deals with the Formula Student competition. There is the analysis of the formula Ford’s anti-roll bar as a starting point for our own design. In the section which deals with the anti-roll bar design several alternatives are designed, the stress analysis of components are made and multi body system models are developed for final solutions. These models serve for further analyses of driving characteristics of the vehicle.
