Optimal tensioning of nonlinear antenna structures
Is Version Of
A new technique is described for optimizing the shape of a hoop/column antenna by adjusting the tensioning loads. The antenna structure is modelled using finite element procedures which include the geometric nonlinearities. The finite element equations constitute nonlinear equality constraints in the optimization problem. The new optimization technique solves this optimization problem without the introduction of either Lagrange multipliers or penalty functions. The results for two sample problems are presented in this dissertation.
