The modeling of a torus solar array

2000 / IEEE / 0-7803-6262-4


This item was taken from the IEEE Conference ' The modeling of a torus solar array ' The focus of this paper is on the geometric imperfection in a parabolic shape associated with inflated structures which are built by joining together the main envelope (i.e. the reflector and canopy), the torus, and catenary support. The parabolic inflated structure is modeled using the finite element method incorporating the commercial finite element code ABAQUS. The purpose of the torus is to provide a stable boundary condition for the main envelope. Furthermore, the type of boundary condition imposed on the main envelope affect the shape of the inflated structure. The interaction between the torus and the reflector-canopy is investigated.
