Neck Rotation

Main Forum

Hi,

I’m very new to the AnyBody software. I’m trying to see the muscle activities of the neck as the head rotates while a person is driving (seated). I’m using the Seated Human Full With Neck model. I have read the tutorials but I was not sure how to proceed. Could I get some help in this?

Thank you in advance,
Hamed

Dear Hamed,

If you look at the JointAndDrivers.any file you can see the following section:


  //Neck driver 
  
  AnyKinEqSimpleDriver CervicalDriver ={
    AnyKinMeasureOrg &Ref1 = .RefHM.Interface.Trunk.SkullThoraxFlexion;  
    AnyKinMeasureOrg &Ref2 = .RefHM.Interface.Trunk.SkullThoraxLateralBending;
    AnyKinMeasureOrg &Ref3 = .RefHM.Interface.Trunk.SkullThoraxRotation;
    DriverPos = pi/180*{0, 0, 0};
    DriverVel = pi/180*{0, 0, 0};
    Reaction.Type = {Off, Off, Off};  
  };

By modifying the DriverPos and DriverVel you can prescribe some motion to the neck.

Regards,

Pavel
