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 Tool_Results_and_Plots.gif (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 Tool_Calculate.gif (MotionManager toolbar).
