I have a structure with springs where a part shows displacements when force is applied. Ideally, I would like to obtain the relationship between force and displacement, such that if I measure the displacement, I can derive the forces and moments acting on this structure at a given point.The result would be a matrix M, with F = M*x -- F being a 6D vector with forces and moments along the xyz axes and x the 6D displacement.
For the first step, I did a static structural analysis with Ansys. I have some questions regarding the next steps,
1) Does Ansys already provide such a force/moment-displacement relationship?
1) Can Ansys output the displacement in 6D instead of just x-y-z?
2) In theory, is the matrix I want to obtain the global stiffness matrix?
I am a bit stuck right now and would appreciate any kind of help or advice! Thank you!
