镜面反射算法在结构可靠性优化设计中的应用
摘要
Abstract
In the traditional structural design, reliability and optimization are two relatively independent and conflict-ing design methods.But realizing structural optimization may compromise reliability, and vice versa.So to find a balance point between the two design methods, to achieve structural optimization and meet the requirement on reliability, reliability optimization is the answer.Optimal design of structural reliability is an effective design method developed by introducing the reliability theory based on optimal structure design and taking reliability as a constraint condition of the optimal design. Specular reflection algorithm is a brand-new holistic intelligent optimization method, with the advantages of high calculation efficiency, strong robustness, etc.The paper puts forward the reliability optimal design method based on specular reflection algorithm, which is used in the reliability optimal design for the simple bridge structure of the overhead crane.The simula-tion result shows that the method can be used to obtain a reliable and optimized result, proving it feasible and effective, in-dicating significant potential of application promotion in engineering works.关键词
