电磁继电器质量形成过程的不确定性建模及稳健设计

The fluctuation of the quality characteristics caused by the uncertainties in the product manufacturing process, is one of fundamental reasons that affect the reliability of the relay. Meanwhile, the lack of quantitative calculation and control methods of the quality characteristics, is the root cause that limits the reliability promotion of relay and other electromechanical components. This project presents a forward modeling and rapid solution method for input and output of relay quality manufacturing process, which quantifies influence of process fluctuation on the input parameters and output characteristics of the relay for the first time, by using progressive iterative compensation method. On this basis, the study of the robustness of volatility suppression and control of the quality are carried out. And a robust global optimization method based on independent response surface modeling is proposed, which suppress the quality fluctuation of the uncertainties by the decoupling and equalization of stability and adjustment factors. Then, the quantitative control of quality fluctuation is achieved by the adaptive allocation of uncertainty factors maximum bounds. The project studies the common basic problem of electromechanical components, and the quality model and robust analysis method that will be researched is very important to the quality and reliability of electromechanical components, therefore has important scientific significance and practical value.

质量形成过程中的不确定性所导致的质量特性波动，是严重影响继电器产品可靠性的根本原因。而质量波动的定量计算及稳健设计方法的欠缺，是制约我国继电器及其他机电元件可靠性有效提升的根源。本项目提出一种继电器质量形成过程的正向建模及快速求解方法，基于渐进迭代补偿首次量化了工艺过程波动对继电器输入参数和输出特性的影响。在此基础上，开展质量波动抑制与控制的稳健性优化研究。提出一种基于独立响应面建模的稳健性全局寻优方法，通过稳定因素和调整因素的解耦与均衡来抑制不确定性因素引起的质量波动。而后通过不确定性因素最大界的自适应分配，实现质量波动的定量控制。本项目所研究的是机电元件的共性基础问题，拟建立的质量波动分析与稳健性优化理论体系对于确定并量化关键工艺指标、提高产品的质量与可靠性具有重要的科学意义与实用价值。
