Rogelj, Jakob (author), Čepon, Gregor (mentor), Boltežar, Miha (comentor)

Magistrsko delo obravnava problematiko vibracijskih bolezni in s tem povezano problematiko karakterizacije biodinamskega sistema, prsta na roki. Natančneje se osredotoči na določitev parametrov togosti povezav numeričnega modela prsta na roki. V delu predstavimo razvit algoritem za določitev optimalne ravnovesne lege sistema v procesu identifikacije togosti spojev. Z uporabo predlaganega pristopa je mogoče lokalizirati vpliv parametrov togosti posameznega sklepa na eno samo lastno frekvenco. Predstavljena numerični in eksperimentalni primer predstavita učinkovitost razvitega algoritma za določitev spojev ter s tem pomembnost pravilne izbire lege sistema tekom izvedbe postopka linearizacije gibalnih enačb.

• Title: Dynamic characterization of joints in the finger-hand biodynamic system

Abstract

The master’s thesis presents the joint-parameter characterization of the finger-hand biodynamic system. The characterization focuses on the joint stiffness identification for numerical model of human finger. Presented novel method introduces the system’s equilibrium-point selection algorithm into the joint-parameter identification process. Using the proposed approach it is possible to localize the influence of the individual joint’s stiffness parameters to one particular natural frequency. The presented case study highlights the efficiency of the developed parameter-estimation procedure and with this the importance of a proper linearization equilibrium-point selection for a reliable and accurate parameter-identification process.
