I USED A MODEL FOR SIMULATING QUARTER CAR OF A VEHICLE .
THE MODEL IS SAME AS INSTRUCTED IN A VIDEO BY MATHWORKS.
UNFORTUNATELY MY SCOPE IS SHOWING SAME RESULTS FOR ROAD INPUT AND SPRUNG MASS.
THE VALUES USED ARE SHOWN IN THE FIGURE.
I HAVE ALSO ATTACHED THE MODEL.

Maybe the signs of your governing equations are wrong and is there any reason for why you have given your road input directly to your unsprung mass instead of the tires ? Try fixing that or use simscape where you won't require any governing equations to build quarter/half car model.
