Abstract (Croatian)

U ovom je radu postavljen model za 2D kinematičku i dinamičku analizu pokreta šake služeći se dinamikom sustava krutih tijela, a koristeći Kartezijeve koordinate. Kinematički problem bavio se analizom pokreta, brzine i ubrzanja, a dinamički analizom unutarnjih sila i momenata koji se javljaju tijekom rehabilitacije. Na početku je dan kratak uvid u anatomiju i fiziologiju ljudske šake, koji je potreban radi boljeg opisivanja modela. Isto tako, opisani su pokreti koje je čovjek u mogućnosti izvesti. Nadalje, kratko je opisana teorija mehanizama, kinematika i dinamika. Prvo su provedena mjerenja pomoću BTS sustava koji se nalazi u laboratoriju za biomehaniku Kineziološkog fakulteta u Zagreba, a zatim su dobiveni podatci (koordinate položaja markera) korišteni u daljnjoj analizi u programskom paketu Matlab. Naposljetku su dobiveni iznosi sila i momenata koji su bitni kod konstruiranja rehabilitacijskog uređaja.

Abstract

This thesis describes a 2D model for kinematic and dynamic analysis of hand movements using the dynamic multibody system of rigid bodies, and using Cartesian coordinates. Kinematic analysisi of the problem dealt with the movement, speed and acceleration, and dynamic analysis with internal forces and moments that occur during rehabilitation. At the begining there will be a brief insight into the anatomy and physiology of the human hand, which is needed in order to describe the model. Also, it describes the movements that a person is able to perform. Furthermore, it describes the theory of mechanisms, kinematics and dynamics. First, the measurements were recorded using the BTS system located at the Faculty of Kinesiology in Zagreb, and then the results of the data (coordinates of the markers) that were used in further analysis in MATLAB were obtained. Finally, the analysis of the obtained results, which can be used at the construction of a rehabilitation unit, was carried out.
