Formula Student Spaceframe Construction
Ženčák, Jan ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
This bachelor thesis describes requirements for Formula Student chassis given by rules and construction of other parts of car. The objective were design construction of the frame with use of high tensile strength steel and perform material tests required by rules of the competition. After rules analysis was chosen chrome molybdenum steel 15 130. Construction design and torsion stiffness analysis were performed. Test samples were manufactured and tested for verification chosen material is according to rules of Formula Student competition.
Deformation Measurement with Use of Measurement Device Tritop.
Janiš, Libor ; Svída, David (referee) ; Blaťák, Ondřej (advisor)
This work deal with, suggestion of measuring procedure of deformation modulus of system Tritop and his application on real instances. Also the measuring procedure of torsional stiffness of vehicle body is designed, and the models of frames including attachment of a car are elaborated, where the measuring of torsional stiffness will be done on.
Dynamic Behaviours of the C Axis Drive for Multifunction Cutting Center
Křepela, Jan ; Marek, Jiří (referee) ; Souček, Pavel (referee) ; Brychta, Zdeněk (referee) ; Singule, Vladislav (advisor)
his Disertation thesis involves the creating of the simulation model of the C axis drive over mentioned machine and them verification on the prototype of this machine. C axis is controlled with position feedback. Simulation model was created before the realisation of the machine prototype for the preliminary identification of the dynamic behaviours in the working cycles and them opportunity of the realisation this conception. C axis is constructed with worm gear and is controlled with help of Master-Slave drive. This torque drive eliminates the production backlash in the worm gear. The multifunction turning center, where is used this C axis, is determinate for heavy duty roughing cutting of the forged peaces, where is problem with dynamic stability of the cutting process. Simulation model includes the problems with multi-body mass system, friction on the worm gear, self locking, damping on the worm gear and the optimization of the parametrs for many regulators. Simulation model was verified on the prototype of the machine. Achieved results bring the new knowledge, which are used for simulation complicated machine nodes and this knowledge is used for research and developing of the similar mechatronics system.
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.
