基于Kringing和贝叶斯优化的飞机翼梁结构可靠性优化
Reliability optimization of aircraft wing beam structure based on Kringing and Bayesian optimization
摘要
Abstract
The practical working conditions of the wing beam structure were established according to the airworthiness regulations to improve the flight performance and safety of the aircraft.The reliability optimization design of the wing beam structure was completed by designing the wing beam structure parameters,constructing the comprehensive objective function,setting the constraint conditions and constructing the reliability optimization mathematical model.The reliability double-layer optimization strategy of Kriging and Bayesian optimization was adopted to solve the problem of the wing beam structure.The results show that with increasing the calls of the objective function,the mass of the wing beam structure shows a significantly decreasing trend,and the displacement of the wing beam structure under different working conditions is also reduced.Finally,the minimum mass of the wing beam structure and the minimum displacement of the wing beam structure under different working conditions are obtained.These research results provide theoretical support for the optimization design of aircraft wing beam structure.关键词
