This example illustrates a double wishbone front wheel automotive suspension. The suspension is mounted on two platforms that can independently move up and down to simulate a road profile on each wheel. For a given pair of road profiles, the resultant roll and bounce of the chassis can be studied and the suspension parameters tuned for optimal performance. The inputs to the two platforms are the road profile and its derivative. The platforms have a PD controller that controls the vertical position of the platform to mimic the input road profile. See "Road Profiles Generator" block dialog for details on the test road profiles.
