Innovation of the existing feeding device solution in the context of an automated and robotic workstation
Porubský, Radek ; Marek, Jiří (referee) ; Knoflíček, Radek (advisor)
This thesis deals with the design of a new version of the production and assembly node, which is part of an automated and robotized workstation for product assembly. The main objective of modifying the original solution is to eliminate the problems of the existing solution and apply innovations to make the work process of the equipment more efficient. The main modification of the original solution is the replacement of the bowl vibratory feeders in combination with linear vibratory feeders by a flexible feeding system with camera and robot. The paper describes the process of designing a new solution for the node, which eliminates the problems of the existing solution and at the same time comes up with new innovations. By solving the problems of the original solution and introducing the innovations, the reliability, speed and smoothness of the working process of the machine is improved. The work includes, among other things, drawings, risk analysis and costing.
Experimental investigation of mechanical properties of structures made by metal 3D print
Porubský, Radek ; Jaroš, Jan (referee) ; Vaverka, Ondřej (advisor)
This bachelor thesis deals with shear testing of lattice structures produced by the Selective laser melting technology. The testing method was based on the ASTM D7078 standard, which deals with the testing of composites. BCC and FCC lattice structures with different strut diameters were selected for the experiment. The work describes the course and results of shear test. These real results are compared with results of finite element analysis. The results compare the properties of structures depending on the diameter of the strut, the type of structure or the direction of loading. The influence of Selective laser melting production technology on the properties of structures under shear loading is also discussed. For example, the results showed that the FCC structure has better mechanical properties under shear loading than the BCC structure. For both structures, it was also confirmed that structures with a larger strut diameter have significantly better properties than those with a smaller strut diameter.
