Design Optimization of Contact Force Vector Sensor
 Vála, Pavel ; Vlach, Radek (referee) ; Krejčí, Petr (advisor)
The aim of this work is an optimalization of vector contact force sensor properties which prototype is at the moment designed. The principle of sensor is based on transformation active part of sensor using three tensiometers and following value indentification of loading force vector using neuron network. Sensor has a bad sensitivity when axis force load or near to axis of sensor. To solve this problem ''MKP'' model of sensor was used on which suitable optimalization method was applicated. From the result of optimalization modificated sensor will be proposed and will be made a utility verification using neuron network.

Overview of present metods and devices for friction coefficient measuring in lubricated contact of rubbing surfaces.
 Nešpor, Vít ; Šamánek, Otakar (referee) ; Koutný, Daniel (advisor)
In this thesis was discussed measuring of friction coefficient. Phenomenon of fiction and basic physical methods of determining friction coefficient. were described. This work was rather oriented to modern advanced methods, realised by experimental devices - tribometers. These devices with methods were described in focus to measuring of friction force. Their advantages or disadvatnages were described too. In detail was discussed the accuracy of methods.
