Engineering design of the vehicle suspension rocker
Poláček, Vojtěch ; Ramík, Pavel (referee) ; Bradávka, Marek (advisor)
Diploma thesis deals with the design and stress analysis of the rocker suspension for an autocross car. The research describes some real cases of using suspension with pushrod and rocker in motorsport. Subsequently, the work deals with the design of the wheel bump/rebound limiting stops and bump/rebound measuring. The challenge is to design a component shape, size and select fit of a rocker with an emphasis on low weight whilst maintaining sufficient strength and rigidity. The design study include stress analysis which leads to optimize the final shape.

Rocker for Formula Student Vehicle
Šprta, Petr ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
This thesis deals with a prototype of the rear suspension rockers of the racing monopost Dragon 10th generation, which is being developed at the Brno University of Technology within the international educational project Formula Student. Based on the research, the technology method of casting has been chosen for this purpose. The input for the prototype of the rocker arms is based on the impacting forces and suspension points given by kinematics of the vehicle. Based on these facts, topology optimization of the shapes has been conducted and the components have been modelled accordingly. Followingly, optimization focused on minimizing weight, deformation and stress were conducted using the reverse loading of modelled components. The last part of this thesis is concerned in the comparison of rear rockers of the last year‘s monopost Dragon 9. Taking into consideration the change of the concept, the mechanical properties of rockers are slightly better.

Design of rocker for mountain bike shock absorber using topology optimization
Zalibera, Tomáš ; Hurník, Jakub (referee) ; Vaverka, Ondřej (advisor)
Submitted bachelor thesis deals with research and comparison of topology optimization software. A given component is 3D scanned, after that, kinematics model is done to define possible load cases. Then, topology optimization is done in four selected software. Results from topology optimization are then validated in FE analysis to acquire maximum deformation and stress. After the FEA the best variant is chosen, which is additionally modified to reach sufficient level of safety factor. The discussion and conclusion chapter deals about final comparison of topology optimization software based on FEA resuls and the most suitable software is choosen, in which decrease of deformation by 27% was achieved with a level of weight a bit lower as with the original rockers.

Rocker and personal finance
Lohonka, Petr ; Smrčka, Luboš (advisor) ; Schönfeld, Jaroslav (referee)
The bachelor thesis deals with alternative investments as wine investment, beer investment, tobacco investment and art investment. In the second part, which is solved in the form of case study, we compose from this investments the investment portfolio of hypothetical rocker.
