A revolute joint. [1]
Modeling Approach[edit]
The joint one frame one each side of the joint, with flanges on the joint and the rotating axis for receiving torques from Rotational elements.
Required Parameters[edit]
None.
Optional Parameters[edit]
| name | type | default | description |
|---|---|---|---|
| n | Modelica.Mechanics.MultiBody.Types.Axis | {0,0,1} | the rotation axis in frame_a |
| phi | SIunits.Angle | 0 | initial joint angle measured in frame_a and rotation axis n, specified as phi( start=startAngle )
|
| phi_offset | SIunits.Angle | 0 | offset applied to the joint's internal angle measurement |
| angle | SIunits.Angle | 0 | joint angle, = phi + phi_offset |
| w | SIunits.AngularVelocity | 0 | initial angular velocity |
| a | SIunits.AngularAcceleration | 0 | initial angular acceleration |
| tau | SIunits.Torque | 0 | driving torque in the axis of rotation |
| useAxisFlange | Boolean | false | whether to constrain the joint according to whatever is attached to the "support" and "axis" flanges, as when adding a rotational damper to the joint |
Public Fields[edit]
