Applying a torque to a kinematic coupled reference point

Applying a torque to a kinematic coupled reference point

Applying a torque to a kinematic coupled reference point

(OP)
I am trying to apply a braking torque to the centre hub of an alloy wheel (i have posted before if you have seen already) I have the rear of the hub kinematicaly coupled to a reference point at the centre of rotation. Is there a way of applying a troque to the reference point to give the center hub a rotational force? I know i can apply rotational displacements which i have ran many analysis for but now i want to apply the force rather than a displacement.



I want to apply 1120N.m of torque

RE: Applying a torque to a kinematic coupled reference point

Hi,

Just apply concatenated load in any rotational degree of freedom for your reference point.
If you do not use local coordinate system for your load then:
- 4DOF is moment along x-dir
- 5DOF is moment along y-dir
- 6DOF is moment along z-dir

If your RP is 1000 and your moment is along x-direction then in inputdeck you have:
