Numerical and experimental study for a beam system with local unilateral contact modelling satellite solar arrays
Numerical and experimental study for a beam system with local unilateral contact modelling satellite solar arrays
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 aremounted 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

Abstract
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 aremounted 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
