Prescribed Rotation

Motion driver that converts input signals into sequential rotational motion

 Description A prescribed rotational motion driver is identical to a Spherical joint, except that the joint rotations are prescribed by input signals, rather than being free to vary.

 Name Description ${\mathrm{frame}}_{a}$ Joint inboard frame ${\mathrm{frame}}_{b}$ Joint outboard frame $\mathrm{PRInputA}$ Real signal input specifying the rotation about the axis specified by the $A-{\mathrm{axis}}_{}$ parameter $\mathrm{PRInputB}$ Real signal input specifying the rotation about the axis specified by the $B-\mathrm{axis}$ parameter $\mathrm{PRInputC}$ Real signal input specifying the rotation about the axis specified by the $C-\mathrm{axis}$ parameter

Parameters

 Symbol Default Units Description Modelica ID $A-{\mathrm{axis}}_{}$ $⟨1,0,0⟩$ - Axis about which rotation A is applied, expressed in inboard frame. RotA $B-\mathrm{axis}$ $⟨0,1,0⟩$ - Axis about which rotation B is applied, expressed in frame resulting from A rotation. RotB $C-\mathrm{axis}$ $⟨0,0,1⟩$ - Axis about which rotation C is applied, expressed in frame resulting from B rotation. RotC
