Workshop mobile handling table
Macejka, Andrej ; Špička, Jiří (referee) ; Škopán, Miroslav (advisor)
This diploma thesis is concerned with the design of lift table with hydraulic actuator system. Lift table is supposed to perform vertical motion and tilting the upper desk in horizontal axis. In background research are explored various suitable movement mechanisms and types of actuating systems. After choosing the right mechanism type for lifting and tilting, actuating system and various design components the force and strength calculations are performed analytically and by finite element analysis. The hydraulic schema, 3D model of assembly and drawings are made.
The study of the MR fluid for space applications
Macejka, Andrej ; Macháček, Ondřej (referee) ; Kubík, Michal (advisor)
This bachelor thesis is concerned with study of off-state rheological properties of magnetorhelogical (MR) fluid. The purpose of this thesis is to define measurement metodology and evaluation inherent rhelogical properties of MR fluids in wide temperature range.
Stationary crusher concrete panels - analysis of dynamic effects in the machine foundations
Macejka, Andrej ; Kříž, Jakub (referee) ; Škopán, Miroslav (advisor)
This diploma thesis is concerned with design and proposal of parameters of drop hammer Davon for crushing of steel reinforced concrete panels with weight of the ram 5 t. The main topic is an emergency condition when there is no crushed material between ram and anvil. The design is established by simulation of an impact by finite element analysis with respect to required ground bearing capacity.
