Design of Low-Pressure Piston Rheometer
Lán, Radek ; Strecker, Zbyněk (referee) ; Roupec, Jakub (advisor)
This thesis is focused in design of Low-Pressure Piston Rheometer intended for experimental identifying of magneto-rheologic (MR) liquid properties at long-term load. MR liquid is briefly introduced in the initial part of the thesis. There follows a search related to way of liquids properties measurement and overview of MR dampers which are close to piston rheometers by their construction. MR dampers with through piston-rod have been emphasised. The second part of the thesis is focused on calculation of magnetic circuit of the rheometer throttle leak. The rheometer is designed in the last part of the thesis.

Modelling and Verification of Piezoelectric Generator
Lán, Radek ; Singule, Vladislav (referee) ; Hadaš, Zdeněk (advisor)
This master's thesis deals with the development and verification of the model of the piezoelectric generator, incl. determination of its parameters. This mathematical model should be used as a tool for development of new devices, especially for analysis of applicability of available energy source (vibration) and for design of device itself. At first the review of energy harvesting is described deeply. Subsequently piezoelectric generators and the ways how we can model them, are depicted in details. The methodology of parameters estimation and model development is presented in state space or in MATLAB/Simulink environment and applied on the commercial generator Midé V21BL. A device has been made within the scope of the thesis, which can be used as an universal tool in experiments with generator. Finally the model is applied on the analysis of energy yield from man's walk and there is also brief introduction to model modifications.

Design of veritcal belt conveyor for powdery material
Tulis, Tomáš ; Kočiš, Petr (referee) ; Lán, Radek (advisor)
The aim of this bachelor’s thesis is to design a vertical belt conveyor for powdery materials with the transport capacity of 100 000 kg.h-1 and the axial distance between the drums of 40 m and height difference of 37 m. The thesis includes a brief description of conveyor belts and their components, design of the main parts of the conveyor, design of the drive of the conveyor according to the standard ČSN ISO 5048 and the calculation of the main structural nodes of the conveyor.
