Quarter Car on Rough Surface
This simulation was part of my MS thesis. I wrote a script that generate surface profile using the PSD data of various terrains*. A quarter car model traverse on the surface and gets excited by the surface elevation.

Note: The animation uses a Matlab script provided here. I modified the script to work with my code.
