Sine Sweep and Steady-state Response of a Simplified Solar Array Model With Nonlinear Support
In this paper the dynamic behaviour of a multi degree of
freedom beam model of a solar array structure is investigated
both experimentally and numerically. The beam is supported by
one nonlinear element, a so-called snubber. This snubber can
only take compressive forces. Two types of excitation are
applied and compared: sine sweep excitation (with different
sweep rates and directions) and steady-state excitation.
Emphasis lies on the investigation of the dynamic behaviour of
the system under prestress, which implies softening behaviour
at the time when snubber and beam loose contact. The system
displays rich nonlinear dynamic behaviour: multiple solutions
(hysteresis loop), superharmonic resonances and subharmonic,
quasi-periodic and chaotic solutions. Good correspondence
between experimental and numerical results has been found
