Hi I'm a beginner to matlab and simulink and have been thrown at the deep end with this project and I am really struggling with the last part.

I've been trying to model a 1/4 car suspension going over a speedbump using matlab and simulink, the matlab code creates the speed bump profile which I believe is correct and the simulink is supposed to model the 1/4 car suspension but the scope is not producing the correct kind of graph like in this project http://www.engin.swarthmore.edu/~dluong1/e12/Lab4/main.htm (look under 'model A standard bump' to see what I mean).

could you help me fix this problem.

this is the simulink mode

this the code

function [road] = make_road(h, l, v)
dt= (l/v);
time = linspace(0,dt);
time = time' ;
rh = (h/2)*(1 - cos(2* pi * time / dt));
plot(time,rh);
xlabel('Time (s)')
ylabel('Displacement of Road')
title(strcat('Speed Bump (', num2str(h),' (m) (', num2str(l),' (m) (', num2str(v), '(m/s))'));
[road] = [ time rh ];
end
