Hi,
I have modelled the transient response of a free-free (unconstrained) beam in ABAQUS, however, I now want to model the transient response when the force is placed on a spring. I have attached a rough sketch of the problem.
I have applied a two point spring to the beam model using a node on the beam and a reference point and placed a concentrated force on this reference point
The issue is that no matter the choice of spring stiffness the transient response is the same as it was without the spring! When i view the response it looks like the spring is moving as a rigid body with the beam, hence why potentially the transient response is not changing.
Any idea how else to model the spring so a force can be placed on it?
