Abstract
Diferencijalna jednadžba drugog reda kojom se modelira harmonijski oscillator izvedena je iz Newtonovih zakona. U ovom su radu promatrani razni slučajevi ponašanja harmonijskog oscilatora: slobodne vibracije bez prigušenja, slobodne gušene vibracije i prisilne vibracije. Matematički model zapisan je i kao sustav linearnih diferencijalnih jednadžbi prvog reda. Svojstvene vrijednosti i svojstveni vektori pripadajuće matrice sustava temelj su za analizu rješenja promatranog sustava. Dobivena se rješenja se prikazuju i u tzv. faznoj ravnini. Taj postupak je izveden u Wolfram Mathematici te variran za različite vrijednosti konstante opruge, mase i koeficijenta gušenja. Naposlijetku su prikazani praktični primjeri primjene na neke mehaničke i električne sustave.
Abstract (english)
The second order differential equation modelling harmonic oscillator is derived from Newton laws. In this paper, various cases of harmonic oscillator behavior are observed: free vibrations without damping, free damped vibrations and forced vibrations. The mathematical model is also written as a system of first-order linear differential equations. The eigenvalues and eigenvectors of the corresponding matrix system are the basis for the analysis of the solution of the observed system. The obtained solutions are also presented in the so-called phase plane. This procedure was performed in Wolfram Mathematica and varied for different values of spring constant, mass and damping coefficient. Finally, practical examples of application to some mechanical and electrical systems are presented.
