Razvoj odprtokodne knjižnice za prikaz podatkov zapisanih v UFF formatu

Trilar, Lovro (author), Slavič, Janko (mentor), Boltežar, Miha (co-mentor)

Glavni namen naloge je priprava in razlaga delovanja odprtokodne python knjižnice uff_widget namenjene uporabi v orodju Jupyter notebook-u. Knjižnica omogoča prikaz zapisanih podatkov v datoteko oblike UFF, ki so pridobljeni med procesom opravljanja modalnega testiranja in modalne analize. Zapisani podatki so geometrija merjene strukture, rezultati modalnega testiranja ter rezultati modalne analize. S temi podatki se lahko v 3D prostoru prikaže nihanje merjene strukture pri različnih frekvencah. Za namen testiranja pripravljene knjižnice se opravi meritve na realni strukturi in opravi modalno analizo. Pridobljene podatke se shrani v UFF datoteko, ki služi kot testna in demonstracijska datoteka za knjižnico uff_widget. Za pravilno pripravo in razumevanje UFF, je povzeta dokumentacija datotečne oblike in knjižnice pyuff.

• Title: Development of an open-source library for displaying data written in the UFF format

Abstract

The main purpose of the paper is to prepare and explain the operation of the open source Python library uff_widget intended for use in the Jupyter notebook. The library allows displaying the written data to a UFF file obtained during modal testing and modal analysis. The recorded data is the geometry of the measured structure, the results of modal testing and the results of modal analysis. With this data, the oscillation of the measured structure at different frequencies can be displayed in 3D space (i.e. Harmonic analysis). For the purpose of testing the prepared library, measurements are made on a real structure and modal analysis is performed. The resulting data is stored in a UFF file that serves as a test and demo file for the uff_widget library. To properly prepare and understand the UFF, paper sumerizes documentation of the UFF and the pyuff library.
