摘　　要：新产品正向设计需综合考虑新结构工艺、多设计变量、复杂工作环境的影响,并合理量化不确定性影响,评估可靠性水平,从而在源头上确保高可靠性。基于确信可靠性理论,研究了基于性能裕量的确信可靠性正向设计优化方法。提出了面向新型扭簧电连接器研发的确信可靠性正向设计优化基本流程,包括设计变量初值优选、性能裕量建模、不确定性量化和确信可靠性分析与优化4部分。以某新型扭簧电连接器的正向设计为例,基于正交实验、响应面建模和模拟退火启发式优化等方法实现了多维离散-连续变量及其不确定性作用下的优化设计。To evaluate reliability of new products,function-oriented design should comprehensively consider the influence of new structure and technology,multiple design variables,and complex working environments,and reasonably quantify uncertainty effects.This will ensure high reliability from the original design.Based on the belief reliability theory,this study investigates a performance margin-based and function-oriented method for belief reliability design and optimization.The basic procedure of the function-oriented reliability design is proposed for the development of new torsion spring electrical connectors,which includes four steps,i.e.,initial value selection of design variables,performance margin modeling,uncertainty quantification,and reliability analysis and optimization.This procedure is exemplified in the design and development of a new type of torsion spring electrical connector.The optimal design of multidimensional discrete-continuous variables under the influence of their uncertainties is realized based on orthogonal experiments,response surface modeling,and simulated annealing heuristic optimization.
