Hi everyone:
I have a question regarding the use of ABAQUS to determine damping coefficients. Basically, I want to find the damping of a skid landing gear via ABAQUS. I'm aware that the only physical way to determine damping would be through an actual experiment.
However, for a given CAD model in ABAQUS, is there an accepted technique to approximate the damping of the structure? Could I edit the Rayleigh Damping Coefficients such that the dynamics fit a certain curve? But this is dependent on whether or not I can find legitimate data plots/curves that describe the motion. Does ABAQUS automatically assign an approximate damping for a given structure with defined material properties?
In other words, I only want to obtain the damping on this ABAQUS model in order to obtain damping coefficients for a completely separate code that I'm writing. Is this feasible?
Thanks
