MacPherson Suspension Kinematics Analysis
Trnková, Lucie ; Fojtášek, Jan (referee) ; Hejtmánek, Petr (advisor)
This bachelor thesis deals with the influence of the position of significant points of MacPherson strut on kinematic characteristics. The first part contains a description of selected suspension parameters, their impact on the driving properties of the car, and a description of MacPherson strut. Furthermore, based on provided data, is prepared a detailed analysis of the influence of kinematics points to individual characteristics. In conclusion, all findings are synoptically summarized so that they can serve as a manual for change of the kinematic characteristics.

Piston for SI Turbocharged Engine 2.0L
Kusyn, Petr ; Bradávka, Marek (referee) ; Svída, David (advisor)
This diploma thesis is focused on solve of design solutions for piston for turbocharged version of Honda K20A engine, especially on reduce of side force acting on piston. There are mentioned methods and on their basis also design solutions for piston to reduce this force. There is also included kinematic and dynamic analysis for each solution and as well their FEM analysis for testing the suitability of these solutions.

Simulation of the 5th car door mechanism
Taušek, Martin ; Škoda, Jan (referee) ; Hadaš, Zdeněk (advisor)
This bachelor thesis deals with simulation of the 5th car door mechanism. The simulation runs in MSC.ADAMS software in which was made simulation model. The model contains several bodies which needed to have the same mechanical parameters as the CAD model of the real 5th door so the simulation was accurate. The opening of door is done by two gas springs, one on each side. These gas springs had to be correctly dimensioned to achieve fully opened door and safety movement as well. The thesis also deals with kinematic and dynamic analysis of the mechanism.

Experimental robotized workplace with delta-robot
Kozubík, Jiří ; Holub, Michal (referee) ; Knoflíček, Radek (advisor)
This diploma thesis was written within Czech-German study programme Production systems (VUT v Brně & TU Chemnitz). This thesis is divided into four main parts. In the first part is brought out the introduction to design of robotic cells. Following part is concentrated on analysis of present state in area of machines with parallel kinematics. The penultimate part, on which is focused the main attention, is dedicated to kinematic analysis of delta-robot. Closing part of this Thesis presents the study of experimental robotized workplace with integrated delta-robot.

Application of the DIC method in the analysis of human movement
Vogel, Arnošt ; Boháč, Petr (referee) ; Návrat, Tomáš (advisor)
This bachelor's thesis investigates the potential of using the DIC method for human motion analysis. The research section provides a description of the Digital Image Correlation technique in both 2D and 3D. Moreover, existing methods for analyzing human motion in the field of biomechanics are presented. The practical part of the thesis consists of three initial experiments, where only a few points on the human body were observed. This is followed by a final experiment that examines a more extensive field of points using the DIC method.

The effect of kinesiotaping for flat foot correction in association with selected parameters of gait for a specific group of people
Michalcová, Eliška ; Zahálka, František (advisor) ; Heller, Jan (referee)
Title: The effect of kinesiotaping for flat foot correction in association with selected parameters of gait for a specific group of people Objectives: The primary objective of this experiment was to determine whether and to what extent the application of kinesio tape to flat foot (utilising a functional correction technique) can influence the positioning of the specific segments of the body and thereby implement change to walking stereotype. Methods: Biomechanical measurement of the gait of eleven specifically selected people with the clinical symptoms of flat foot was implemented. First we recorded measurements prior to the intervention and then again, subsequent to the application of kinesio tape for a defined period. Probands retained the tape in place for the following four days and then the measuring was repeated both prior and subsequent to the removal of the tape. To determine any potential changes to the statics, initially the measuring of the postural stability prior to the intervention was first implemented in the experiment and subsequently again when the kinesio tape was removed after it had been worn for four days. This measurement was carried out using the Footscan apparatus (RSscan International, Belgium) and any potential differences in six variant modes of posture were determined....

Experimental investigation of human gait analysis parameters
Hrušková, Natália ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Title: Experimental investigation of human gait analysis parameters Objective: The main objective of diploma thesis was an experiment, that examined kinematic and dimensional parameters of human gait which was captured by several cameras and acquired data was recorded in 2D and 3D measurement. Secondary objective was to compare and statistically evaluate data acquired from measurement. The objective of analysis was to discover and describe possible regularities, patterns of human gait and other connections in investigated subjects. Methods: Comparative method was used in the thesis. The purpose of the experiment was to compare parameters measured during attempts of every subject that were conducted under different conditions (different velocity, dressed, undressed, in the environment of 2D and 3D recording) and also to compare different subjects with each other. Results: In the experiment we observed that it is possible to prove the relation between the length of a step and the velocity of gait and also the relation between the change in the body height and the velocity of human gait by three dimensional recording of gait and its analysis. This contention was confirmed in the comparison dressed and undressed subjects. The result of the experiment was, that with increasing velocity of gait is...

Assessment of the timing of tennis strokes using kinematic analysis and surface electromyography
Harrer, Jakub ; Kočíb, Tomáš (advisor) ; Pravečková, Petra (referee)
Title: Assessment of the timing of tennis strokes using kinematic analysis and surface electromyography Aims: Assess the timing of tennis forhand, service and appropriate training exercises using kinematic analysis. Describe the activation of muscles in time for the chosen execution of the strokes by recording surface electromyography (SEMG). Compare the results of various executions and describe the differences between using the racquets with different parameters and between executions of various training exercises. Method: Case study using kinematic analysis and surface electromyography was made. Results: We have found out that the execution of the strokes using the players own racquet was the most stable. We have found the differences in timing while using various racquets. The heavier the equipment we are using in training exercise is the more different is the timing of this movement. We concluded that the chosen training exercises are inappropriate as the special exercises to improve coordination. Key words: tennis, timing, service, forhand, electromyographic analysis, kinematic analysis
