Numerično modeliranje nelinearnega vsiljenega nihanja : diplomski seminar na bolonjskem študijskem programu 1. stopnje Fizika

Petek, Marko, fizik

V diplomskem seminarju obravnavamo resonančno krivuljo magnetnega nihala, ki je primer nelinearnega oscilatorja. Najprej predstavimo analitično rešljiv primer linearnega oscilatorja in zatem ... numerično analiziramo oblike resonančnih krivulj magnetnega nihala. Ugotovimo, da se obnaša podobno, vendar ne enako, kot Duffingov oscilator s trdo vzmetjo. Resonančna krivulja se pri visokih amplitudah vsiljevanja nagne v desno in ima pri nekaterih vrednostih frekvence vsiljevanja dve možni amplitudi. Numerično izračunano resonančno krivuljo magnetnega nihala primerjamo z eksperimentalno izmerjeno krivuljo, a ujemanje ni zadovoljivo. Eksperimentalnemu obnašanju se približamo, če v matematičnem modelu Hookovo vzmet zamenjamo s trdo vzmetjo. Orodje za numerično analizo nihal je avtorsko delo, zato na koncu predstavimo tudi uporabljene algoritme in preverimo njihovo natančnost ter zanesljivost.
