GT-SUITE VTDesign User's Manual

Polynomial Function: Dropdown list has three choices: • Cam Shape- The radius of curvature will be calculated directly from the cam shape. • Flat Follower Lift- The radius of curvature will be calculated based on a flat follower lift profile. • Roller Follower Lift- The radius of curvature will be calculated based on a roller follower lift profile. Roller Radius: Radius of the roller follower when Roller Follower Lift is selected. The radius of curvature of the cam shape will be calculated with this information and does not affect any other results.

Input Data This will open the Input Data window, in which numerical values of user constraints for Lift and its derivatives along with the boundary angles can be entered. This feature is also accessible through the "Edit" menu.

Output Data This will open the Output Data window, in which the calculated polynomial coefficients can be found in one folder and the corresponding values of lift, the derivatives and radius of curvature can be found in another. This data can be copied and pasted into other Windows programs such as spreadsheets. This feature is also accessible through the "Edit" menu. For further information about how to interpret the values in the Coefficients folder, please see the "Output Data" section.
