You can use the Curve Manager to modify property files for the following components:
■Frequency Bushing (if the Ride plugin is loaded)
■General Bushing (if the Ride plugin is loaded)
■Bearing (if the Driveline plugin is loaded)
■Clutch Force (if the Driveline plugin is loaded)
■Wet Clutch (if the Driveline plugin is loaded)
■Complex Spring (if the Driveline plugin is loaded)
■Ride Tire (if the Driveline plugin is loaded)
■Torque Converter (if the Driveline plugin is loaded)
■Dyno Motion Series (if the Driveline plugin is loaded)
■Dyno Curve (angle) (if the Driveline plugin is loaded)
■Dyno Curve (time) (if the Driveline plugin is loaded)
About the Curve Manager Views
There are four possible views in the Curve Manager:
■Plot View
■Data Table View
■Plot and Data Table View
■Property Table View
In each of these views you can:
■Switch to the other view. From the View menu, select Plot, Data Table, Plot and Data Table, or Property Table.
■Edit the data:
■Plot view - You can manually adjust the profile of the curve by selecting an appropriate hotpoint and dragging that point in either the positive or negative vertical direction. Note that you cannot drag Hotpoints horizontally. Certain elements (such as the Complex Spring) contain 3D curves. In those cases you can choose whether to visualize the data as a 2D or 3D plot.
■Data Table view - You can insert or delete rows of data. You can also enter new values for your plot data by highlighting the text box you want to modify and typing the new values.
■Plot and Data Table view - You can interact with both the plot and the data table, and update one from the other.
■Property Table view - Certain property files enable this option, such as Adams Ride bushings. This mode allows you to manually change multiple parameter values stored in the property file.
About the Curve Manager Interface
Note: | Note that the two pull-down menus at the top left of the Curve Manager are informational. |
■The first menu displays the type of component with which you are working. For bushings, you can display data for translational or rotational bushings.
■The second menu displays the component characteristic for which the Curve Manager displays data. For bushings, you can display data for the x, y, or z characteristics.
In both views, along the left side of the window, are options that are shared by both views and options that are specific to each view:
■For information on the options shared by both views, see the help for the different components.
■For information on the options specific to each view, see Curve Manager Plot View or Curve Manager Table View.
