基于GO法和MSIMOSMA的全机结构试验系统可靠性优化设计
Reliability Optimization Design of the Full-Scale Structural Test System Based on GO Method and MSIMOSMA
摘要
Abstract
The reliability optimization design of the full-scale structural test system(FSST)is essential for ensuring smooth test execution and obtaining accurate results.Traditional methods often overlook the complex characteristics of such systems and the robustness of the optimization outcomes.To address these limitations,we propose a new reliability optimization approach for FSST,combining the GO method with a multi-strategy improved multi-objective slime mould algorithm(MSIMOSMA).First,the optimization objectives of maximizing system reliability,minimizing testing costs,and maximizing the robustness of optimization results are established,with component and system reliability design indicators as constraints.A reliability optimization model for FSST is then formulated.Next,to account for complex system characteristics,such as component accumulation,backup correlation,and multi-loop feedback,the GO method is used to develop a reliability assessment model.The MSIMOSMA is then applied to solve the multi-objective optimization problem.Finally,a case study is conducted,which results in an optimized reliability interval for key components of the system.Compared to traditional multi-objective optimization methods,the proposed approach improves the HV metric by 10.1%and reduces the SP metric by 30.8%,demonstrating the superior performance of the method in optimizing the reliability of FSST.关键词
