| Abstract: | At first, x + w2x = + o , the differential equations of the oscillation of spring oscillator under constant friction resistance are given, and the general form of the solution for each stage is induced after being solved stage by stage. Then, according to the regularity of amplitude attenuation and the number of semi-periods of oscillation, the programs are written, and the graphs of oscillation are drawn by Qbasic. |
