Plotting Normalized Rodrigues Parameters

Rodrigues parameters specify the transformation of coordinates between a rotating frame and another reference frame. You can plot normalized Rodrigues parameters to specify the rotational orientation of a moving part.

1. From a Motion Analysis study, click Results and Plots (MotionManager toolbar).
2. In the PropertyManager, for Category, select Other Quantities.
3. For Subcategory select Rodriguez Parameters.
4. For Select result component, select one of the following:
   • Parameter 1 to calculate the first Rodrigues parameter.
   • Parameter 2 to calculate the second Rodrigues parameter.
   • Parameter 3 to calculate the third Rodrigues parameter.
5. For features , select a part face to calculate the result for the rotational motion of the part.
6. Select the Plot Results options you require, and click .
   The result appears in the MotionManager tree.
7. Click Calculate (MotionManager toolbar).
