Abstract: The optimization design for antenna structures with random parameters and under random loads is investigated. The randomness of the structural physical parameters, geometry dimensions and the stochastic loads applied on structures are considered totally. Adopted finite element method, the antenna reflecting surface precision and strength/stability of structural elements are numerically analyzed, and the structural optimization design model is constructed. A simu lated example of eight-meter diamerer antenna confirms the flexibility and validity.
Keywords: random parameters, random loads, antenna structure, finite element and reliability analysis, optimization design.
