magistrsko delo
Abstract
Magistrsko delo obravnava izdelavo in uporabo prenosne mize za simulacijo tako harmoničnega vzbujanja kot tudi horizontalne komponente realnega potresnega vpliva v eni smeri. Premična plošča potresne mize je dimenzij 50 x 50 x 1 cm in maksimalne nosilnosti 80 kg. Potresno mizo poganja servomotor moči 400 W, ki se upravlja prek računalniškega programa Matlab. Vrednosti hitrosti in pospeškov potresne mize pri izvajanju simulacij dobimo s programi, ki so sestavni deli magistrskega dela.
Izdelan je bil tudi 3D model s tremi dominantnimi prostostnimi stopnjami, na katerega smo aplicirali tako harmonično vzbujanje z različnimi amplitudami in frekvencami kot tudi simulacije realnih potresov. Rezultate analiz simulacij na potresni mizi, kot so dušenje, lastne frekvence, nihajni časi ter notranje statične količine, smo primerjali z računskim modelom, dobljenim z metodo končnih elementov. Z magistrskim delom je pokazano ujemanje teorije z realnim obnašanjem konstrukcije pri dinamični obremenitvi. Poleg strokovno-praktičnega aspekta izvedbe eksperimentov na modelu s ciljem pridobitve kvalitetnejših informacij o odzivu konstrukcij nam je potresna miza omogočila realnejšo vizualno predstavo o odzivu konstrukcije.

Secondary title: |
Construction and implementation of a seismic table for the simulation of earthquakes and experimental dynamic response analysis |
Secondary abstract: |
The master's thesis includes production and use of desktop earthquake simulator of harmonic excitations as well as horizontal components of a real earthquake load in one direction. The simulator is 50 x 50 x 1 cm with 80 kg vertical bearing capacity. It is run by 400 W servo motor governed by Matlab computer programme. The simulator's speed and acceleration are obtained by programmes which are incorporated into the thesis.
A 3D three-degree-of freedom model has also been made. Harmonic excitations of various amplitudes and frequencies, as well as real earthquake simulation have been applied to it. The desktop earthquake simulator's results such as damping, natural frequency and internal forces have been compared with the calculations aquired by the finite element method. The thesis deals with the concurrence of theory and practice in regard with the constuction on dynamic load. Along with the practical experiments performance on models the goal of which is to obtain information on construction's dynamic response, the desktop simulator enables realistc visualisation of the dynamic response. |
