NOTES

  1. A dead load is a set of known, time varying forces and moments applied at vertex Vertex0. This vertex could be the vertex defining the relative motion of a joint. For instance, a torque can be applied at a the vertex defining the relative rotation of a revolute joint. In this case, the applied torque is equivalent to a set of torques of equal magnitudes and opposite signs applied on the two components of the revolute joint. This would model the situation of a motor located at the revolute joint applying equal and opposite torques to the rotor and stator, i.e., to the two components on the revolute joint.
  2. The time history of the applied load is determined by 1D function Fun1DName.
  3. F = (F1, F2, F3) and M = (M1, M2, M3) are the components of the applied force F and moment M vectors, respectively. If no FrameName is defined, the components of the force and moment vectors are measured in inertial frame I. If the FrameName is defined, the components of the force and moment vectors are measured in the frame FrameName, that can be a fixed frame or a moving frame.
  4. The applied load at an instant is the product of the applied force and moment times the scaling factor times the time function value at that instant.
  5. If the FfFag = YES, the specified load will be treated as a follower force, i.e. the direction of the applied force and moment vectors will rotate according to the rotation of the structural point where the load is applied. Default value: FfFag = NO.
  6. It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
