To change the roll angle versus lateral acceleration vehicle characteristic, modify the spring by creating and assigning a new property file.
After you create a spring property file, assign the newly created property file to the front and rear springs.
1. To create a new spring property file:
1) From the Tools menu, select Curve Manager. 2) From the File menu, select New.
3) Verify that Type is set to spring. 4) Select OK.
ADAMS/Car generates a plot of the spring displacement versus force characteristic in the plot window of the Curve Manager.
5) In the Slope text box, enter 225.
6) Make sure the extension/compressions limits are set to -100, 100.
7) Select Apply.
ADAMS/Car modifies the spring characteristic. 8) In the Free Length text box, enter 300.
9) Select Apply.
10) From the File menu, select Save. 11) In the File text box, enter my_spring. 12) Select OK.
13) Close the Curve Manager.
ADAMS/Car returns to the main window.
2. To modify the springs:
1) In the model, right-click the front spring, ns[lr]_ride_spring, and then select Modify. The Modify Spring dialog box loads the spring parameters in the text boxes.
my_spring.spr.
3) Replace Installed Length with Preload. 4) Enter a Preload of 5500.
5) Select Apply.
ADAMS/Car assigns the new property file to the spring. 6) Repeat Steps 1 through 4 for the rear springs.
