Multibodies
Multibodies collect and organize ellipsoids, multibody planes, and multibody joints and are typically used in multi-body analysis.
Ellipsoids, multibody planes, and multibody joints can be organized into a multibody using the Organize panel. Every ellipsoid, multibody plane, and multibody joint must be organized into one, and only one, multibody and therefore are mutually exclusive to a multibody. Newly created ellipsoids, multibody planes, and multibody joints are automatically organized into the current multibody.
Operations performed on a multibody collector affect ellipsoids, multibody planes, and multibody joints within the multibody collector. For example, if you delete a multibody collector, the ellipsoids, multibody planes, and multibody jonts within the multibody collector are also deleted.
MADYMO
| Card | Description |
|---|---|
| BODY.DEFORMABLE | Deformable body. body local system and center of gravity are not used. Enter the number of MODEs in MODE_LIST and select each applicable MODE element. Select the DAMPING check box to apply MODAL_DAMP. |
| BODY.FLEXIBLE_BEAM | Flexible beam. body local system and center of gravity are not used. |
| BODY.RIGID | This element contains the information necessary to define a unique rigid body: mass,
inertia matrix and location of center of gravity. body local system = ORIENT_INERTIA. If you 'use' the referenced system, no system of a JOINT or BODY should be selected. center of gravity = CENTRE_OF_GRAVITY |
| JOINT | |
| SURFACE.CYLINDER | Hyper-elliptical cylinder. |
