shoulder torque definition problem

Hi
I’m Reza
I have used AnyBody for shoulder modeling. I utilized repository 7.
Now I’m wondering how could I apply external torque to GH joint. In shoulder
repository there is joint folder and in GH joint definition, GH has considered
as a AnyKinRotational.
I don’t know what is AnyKinRotational joint.
I tried to use AnyForce command to this joint to definite torque. but I got no
good results.
I think because this joint has 3 DOF, I should use AnyMoment3D. but I don’t know
how can i use it.  I wrote the codes bellow:
Â
AnyMoment3D ghTorque = {
AnyKinRotational & ref1=…Right.ShoulderArm.Jnt.GHRot;
Mlocal = {10 ,0,0};Â
};
Â
when I run it I get some error that tell me member class “AnyRefFrame” should be
added in this command. I can’t understand it. Would you please tell me how could
I use AnyMoment3DÂ for gh joint and give me an example. This is very important
for me.
Thanks
Reza

Hi Reza,

The AnyMoment3D should be applied directly to a segment. You can for example
write this:

AnyMoment3D ghTorque = {
AnyRefFrame & ref1=…Right.ShoulderArm.Seg.Humerus;
Mlocal = {10 ,0,0};
};

This will apply the moment to the humerus segment in its own local
coordinate system. Of course you can apply it to any other segment or node
of your choice. You can also apply the moment to the same segment but in
global coordinate system by using M = {10 ,0,0};

Best regards,

Sylvain, AnyBody Support
