Components for Rigid Body Centroidal Inertia Measures
The rigid body centroidal inertia measure reports the centroidal inertia of the rigid body with respect to a selected frame of reference, and as expressed in a selected coordinate system. When you create a centroidal inertia measure, you must specify the following options:
• Components
◦ Ixx—The component aligned with the X axis in the selected coordinate system.
◦ Iyy—The component aligned with the Y axis in the selected coordinate system.
◦ Izz—The component aligned with the Z axis in the selected coordinate system.
◦ Ixy—The component in the XY plane of the selected coordinate system.
◦ Ixz—The component in the XZ plane of the selected coordinate system.
◦ Iyz—The component in the YZ plane of the selected coordinate system.
• Reference
◦ COM—Centroidal inertia is calculated at the rigid body's center of mass.
◦ LCS—Centroidal inertia is calculated at the selected rigid body's local coordinate system.
• Coordinate System—Accept the default, which is the ground body WCS, or select a coordinate system on another rigid body in the mechanism. Centroidal inertia values are expressed in the selected coordinate system.
