Simulating a Single Bump
In this section, you set up the four-post test rig to accept inputs stored in tabular functions that you can create and modify using the Adams Car Curve Manager. You will use such a function to simulate the left side of the car driving over a bump in the road.
To set up the test rig:
1. After you’ve returned to Adams Car Ride, ensure that the Full-Vehicle Analysis: Four Poster Testrig is still open. If it is not, open it as you did in Setting up the Analysis.
2. Enter the following specifications:
■Output Prefix: bump
■End Time: 0.5
■Target Value for Basis: 500
3. Select Set Up Road Profiles.
4. Set Profile Source to table functions.
5. Set Vehicle Speed to 100 km/h.
6. For the Left-Wheeltrack Profile, right-click the File Name text box, and then search the <aride_shared> database for the file bump_1inch.rpt.
7. For the Right-Wheeltrack Profile, right-click the File Name text box, and then search the <aride_shared> database for the file flat.rpt.
8. Select the Curve Manager tool 
to the right of the left-wheeltrack file name.
to the right of the left-wheeltrack file name.The Curve Manager displays a plot with a 25.4 mm rectangular bump from
x = 1 (m) to x = 2 (m), where x is the road station (the distance traveled down the road, projected into the global x-y plane).
x = 1 (m) to x = 2 (m), where x is the road station (the distance traveled down the road, projected into the global x-y plane).
9. To close the Curve Manager, select Cancel. You can ignore any warnings Adams Car Ride might issue.
10. In the Road Profile Setup dialog box, select OK.
11. In the Full-Vehicle Analysis dialog box, select OK.
