Hi everyone;
I designed a quarter car model with one degree of freedom in Simulink and collected the acceleration values on the roads with it. However, when analyzing my model in simulink, I found that my results were very meaningless. The double integral of the acceleration data will give the displacement in the z axis. but this x graph (displacement) shows a continuous increase..?

It seems normal to me. The acceleration has positives and nagatives, thus the speed shows rising and falling, but because all the speed values are positive, the displacement will show a continuous increase.
