Components for System Centroidal Inertia Measures
When you create a total centroidal inertia measure, you must specify the following options. All components are expressed in the WCS coordinate system.
Components
Ixx—The component aligned with the X axis in the ground body WCS.
Iyy—The component aligned with the Y axis in the ground body WCS.
Izz—The component aligned with the Z axis in the ground body WCS.
Ixy—The component in the XY plane of the ground body WCS.
Ixz—The component in the XZ plane of the ground body WCS.
Iyz—The component in the YZ plane of the ground body WCS.
Reference
WCS–Centroidal inertia is calculated at the origin of the ground body WCS.
COM–Centroidal inertia is calculated at the mechanism's center of mass.
