Numerical and Experimental Study for a Beam System with Local Unilateral Contact Modeling Satellite Solar Arrays. (arXiv:0910.0094v1 [math.NA])

The mass reduction of satellite solar arrays results in significant panel
flexibility, so possibly striking one another dynamically leading ultimately to
structural damage. To prevent this, rubber snubbers are mounted at well chosen
points of the structure and they act as one sided linear spring; as a negative
consequence, the dynamic of these panels becomes nonlinear. The finite element
approximation is used to solve partial differential equations governing the
structural dynamic. The models are validated and adjusted with experiments done
in the ISVR laboratory, Southampton university.
