Uklon tankega elastičnega nosilca v ravnem ozkem kanalu

Grum, Van (author), Brojan, Miha (mentor)

Uklon nosilca v kanalu ima pomembno vlogo na različnih področjih, kot so naftna industrija, bioinformatika in medicina. Za pridobitev numeričnih rezultatov je uporabljena dvostopenjska minimizacijska shema, ki temelji na Viterbijevem algoritmu in metodi SLSQP, medtem ko je za eksperimentalne rezultate izdelana merilna postaja. V delu je izvedena primerjava med numeričnimi in eksperimentalnimi podatki, ki pokaže, da je razviti numerični model ustrezen za opis uklona tankega elastičnega nosilca v ravnem ozkem kanalu ob predpostavkah, da so stene kanala neskončno toge in da na stiku ni trenja.

• Title: Buckling of a thin elastic beam in a straight narrow channel

Abstract

The deflection of a beam in a channel plays an important role in various fields, such as the oil industry, bioinformatics, and medicine. A two-stage minimization scheme based on the Viterbi algorithm and the SLSQP method is used to obtain numerical results, while a dedicated measuring setup is developed for experimental data. A comparison between numerical and experimental results shows that the developed numerical model is suitable for describing the deflection of a thin elastic beam in a straight narrow channel under the assumptions of infinitely stiff channel walls and a frictionless contact.
