Procedure Verify the model Draw the Simulation diagrams and program it on SIMULINK Do the five cases

Procedure step 3 Case 1: Simulate the system with the parameters above to predict the vertical velocity and accelerations of the driver seat as car moves over a step. y(t) = is a step of magnitude 0.05 meter. Select a suitable time horizon. Case 2: Simulate the system with the parameters above to predict the vertical velocity and accelerations of the driver seat when the road surface is modeled by.

Procedure step 3 Case 3: How does the behavior change when more passengers are added. Repeat Case 2 with Mb = 350kg and 400 kg. Case 4: What happen if the tire’s spring constant is reduced to N/m? Repeat Case 2 with the new spring constant. Case 5: What happen if the shock absorber damping coefficient is reduced to 90%, and 80% of its original value? Repeat Case 2 with the new damping coefficient.
