Abstract

Abstract

To shorten the design cycle and enhance the overall performance of composite radome, a multidisciplinary optimization method is proposed. The optimization model is established and the optimization variables, objects and constraints are analyzed. An optimization scheme is proposed which takes the electrical properties as the objects and the mechanical properties as the constraints. The aperture integration-surface integration (AI-SI) method is employed to analysis its electrical properties while the finite element method (FEM) is employed to analysis its mechanical properties. The optimization process is established based on the multi-island genetic algorithm (MIGA). Numerical analysis of an example is carried out and the results show that the electrical properties of the radome are successfully improved under the ensurance of mechanical properties. The feasibility of the optimization method is validated.
