Knez, Luka (author), Boltežar, Miha (mentor), Slavič, Janko (co-mentor)

Raziskava predstavi pregled potrebne teorije in standardov za raziskovanje biodinamičnega odziva telesa ter njegove vibroizolacijske zaščite. V prvem delu sta razviti dve različni biodinamični merilni napravi. Prva je zasnovana kot ročaj in ločeno ter sočasno zajema odzive dlani in prstov na vibracijsko vzbujanje. Naprava omogoča izvajanje meritev v vseh treh smereh prostora, lahko se jo tudi uporablja za preverjanje učinkovitosti antivibracijskih rokavic. Druga naprava pa je bila razvita z namenom izvajanja meritev biodinamičnega odziva posameznih prstov in delov prstov. Na podlagi pomerjenih rezultatov je nato razvit in tudi validiran dinamski model kazalca. Model prsta je zasnovan kot sistem togih teles, materialni podatki modela pa so bili identificirani na osnovi eksperimentalnih podatkov. Razviti model služi kot simulator odziva prsta na vzbujanje in ob dodatnih vibroizolacijskih elementih omogoča razvoj in testiranje antivibracijske zaščite človeških rok. Na koncu so s pomočjo nadgrajenega modela prsta raziskani še različni vibroizolacijski materiali in podani predlogi antivibracijske zaščite.

Abstract

This research presents an overview of the necessary theory and standards for the research of the biodynamic response of a human body and its' vibroisolation protection. In the first part, two different biodynamic measuring devices are developed. The first device is designed in the shape of a handle and separately and concurrently measures the palm and finger responses to vibration excitation. The device enables triaxial measurements and can also be used for antivibration gloves testing. The second device was developed for single finger and finger parts biodynamic measurements. Based on the measured results a finger dynamic model is developed and also validated. The analytical finger model is designed as a system of rigid bodies and the material properties of the model were identified from the experimental data. The developed model serves as a simulator of the finger response to excitation and with added vibroisolation elements helps in the development and testing of antivibration protection of the human hands. At the end of this work, the upgraded analytical finger model is used to research different vibroisolation materials and some antivibration protection proposals are listed.
