Composite Chassis for Formula Student
Mende, Milan ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The Master’s thesis deals with the design and production of a composite chassis of the new formula Dragon X. The carbon prepreg used for manufacturing of the monocoque was to be operated at high temperatures. Therefore, this thesis deals with the application of composites structures in the high temperature environment. The thesis addresses the torsional stiffness problematics and it was not only physically tested, but also simulated by FEM analysis and the results were compared.
Design of topologically optimized upright for pneumobil race car
Mende, Milan ; Červinek, Ondřej (referee) ; Vaverka, Ondřej (advisor)
This thesis deals with the design of lightweight front uprights of pneumobile Javelin using topology optimization, followed by manufacturing by additive technology Selective Laser Melting. Aluminium alloy AlSi10Mg was used. Topology optimized parts should have met the requirement of minimal safety factor equal to 2, therefore the stress strain analysis was performed using FEM. The maximal deformation was determined and the safety factor obtained. Two unsymmetrical uprights were designed due to parameters of the brake system. The precision of manufacturing was verified by optical digitization. Machined uprights were mounted on the pneumobile and tested directly on the vehicle. No limit states were observed during testing and subsequent races, so they proved to be fully functional. Weight of the left upright was reduced from 1 609 g to 758 g, the right one was lightened to 741 g.
