基于自适应网格的可靠度预测算法及应用
An Adaptive Mesh-based Reliability Prediction Algorithm and Application
摘要
Abstract
The effective traversal of the input space is an important condition for ensuring the accuracy of reliability prediction.However,existing reliability prediction methods either can not guar-antee the traverse of the entire input space or require a large number of samples to ensure effective traversal of the input space.To this end,this paper proposes a reliability prediction algorithm based on adaptive mesh,whose core is to efficiently divide the input space through adaptive mesh and use breadth-first search for the complete traversal.In addition,the method also uses pruning and inference to further improve its efficiency.Through numerical verification and comparison with other mainstream methods,the accuracy and efficiency of the proposed method are proved.Finally,the paper also dem-onstrates the practicability of the proposed method through its application to the reliability assessment of a berthing structure.The results show that the proposed method can not only traverse the entire in-put space with fewer samples but also has satisfactory accuracy and efficiency of reliability prediction,and it is applicable to highly nonlinear performance functions.关键词
