Package Parts contains rigid components of a multi-body system. These components may be used to build up more complicated structures. For example, a part may be built up of a "Body" and of several "FixedTranslation" components.
Model | Description |
---|---|
Fixed | Frame fixed in world frame at a given position. It is
visualized with a shape, see shapeType below (the
frames on the two sides do not belong to the component): |
FixedTranslation | Fixed translation of frame_b with respect to frame_a. It is
visualized with a shape, see shapeType below (the
frames on the two sides do not belong to the component): |
FixedRotation | Fixed translation and fixed rotation of frame_b with respect to
frame_a It is visualized with a shape, see
shapeType below (the frames on the two sides do
not belong to the component): |
Body | Rigid body with mass, inertia tensor and one frame connector.
It is visualized with a cylinder and a sphere at the center of
mass: |
BodyShape | Rigid body with mass, inertia tensor, different shapes (see
shapeType below) for animation, and two frame
connectors: |
Fixed BodyBox | Rigid body with box shape (mass and animation properties are
computed from box data and from density): |
BodyCylinder | Rigid body with cylinder shape (mass and animation properties
are computed from cylinder data and from density): |
PointMass | Rigid body where inertia tensor and rotation is
neglected: |
Mounting1D | Propagate 1-dim. support torque to 3-dim. system |
Rotor1D | 1D inertia attachable on 3-dim. bodies (without neglecting
dynamic effects) |
BevelGear1D | 1D gearbox with arbitrary shaft directions (3D bearing frame) |
Components Fixed,
FixedTranslation, FixedRotation
and BodyShape are visualized according to
parameter shapeType, that may have the following
values (e.g., shapeType = "box"):
All the details of the visualization shape parameters are given in Visualizers.FixedShape
Colors in all animation parts are defined via parameter color. This is an Integer vector with 3 elements, {r, g, b}, and specifies the color of the shape. {r, g, b} are the "red", "green" and "blue" color parts, given in the ranges 0 … 255, respectively. The predefined type MultiBody.Types.Color contains a menu definition of the colors used in the MultiBody library (this will be replaced by a color editor).
