Structural Reliability Optimization with Fourier Orthogonal Neural Network Method

The structural optimization design considering reliability requirements was proposed based on Fourier orthogonal neural network method. The reliability-based optimization design of the structure is a combination of the structural reliability theory and mathematical optimization methods. The Fourier orthogonal neural network was used to analysis reliability of the structure and also to simulate the relationship between the fatigue reliability and geometry dimension of the structure. The structural reliability requirements were taken as constraints while the structural volume as the objective function, with Fourier orthogonal neural network method, the optimization results of the structure was obtained with a minimum cost, thus can make technical and economic benefits besides the structural reliability.
