Transtibial prosthesis for recreational swimming
Křemen, Jan ; Mazůrek, Ivan (referee) ; Paloušek, David (advisor)
This thesis deals with the construction of an active transtibial prosthesis for recreational swimming. Its aim is to create a working sample of such a prosthesis. The device will primarily serve the patient to move in water - it will be attached to the stump and it will be driven forward. Secondarily, the prosthesis can be used for walking, in the sense that the patient attaches the prosthesis near to a water surface (pool, lake, ocean) and comes with it to the shore. As part of the design and electronics it will be necessary to determine the characteristics of the human resistance in water depending on speed and to determine the necessary propulsion (thrust) strength of the propeller, which will serve as the driving force. Subsequently there will be formed structural variants and selected the best one. This will become default for design and construction of simplified testing device, which will be tested for static thrust. After verifying the functionality and reliability, the final functional sample will be manufactured and tested too.
Influence of hod dip galvanizing on properties of high-strenght steels
Křemen, Jan ; Suchánková, Ivana (referee) ; Kubíček, Jaroslav (advisor)
This thesis deals with the influence of hod dip galvanizing on properties of high-strenght steel. Galvanizing adversely affects the mechanical properties of high-strenght steel. This paper also examines the influence of hod dip galvanizing at hardness high-strenght steels. The task is to assess how the yield stress can galvanize steel.
Contactless torque sensor
Křemen, Jan ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This bachelor´s thesis aims to develop the conceptual and experimental study of the assembly function for non-contact measurement of torque basic project design and the monitoring of key components of the mechanical dimensions of the prototype device BMK-1. The object of this work is only a part of the mechanical equipment. Inspections will be conducted through simple calculations of elasticity strength.
