Скачать или смотреть Spring Mass Damper Animation

Animation of a spring mass damper (a classic system for teaching the fundamentals of dynamic response) excited by a sine wave force at constantly increasing frequency along with a Bode plot of the system. This was created via a Matlab .M script.
Bode Plot (shown at the end): The upper plot shows the magnitude of the system response as a function of the excitation frequency. The lower plot shows how the phase of the system response compares to the excitation.

The code to create this was hastily written and, all in all, is pretty crude. But, since people have asked for a copy, you should be able to find it here: https://github.com/JimKerns/Video-sam...

You have to un-comment:
%Mass = 2;
%K = .5; % spring constant
%B = .25; % damping
or provide your own values.
