【摘要】：加工系統(tǒng)可靠性是保證產(chǎn)品質(zhì)量和生產(chǎn)率的重要因素之一。在多工序加工系統(tǒng)中，系統(tǒng)的停工可由系統(tǒng)要素故障或產(chǎn)品質(zhì)量不合格引起，因此多工序加工系統(tǒng)的可靠性應(yīng)當(dāng)同時考慮系統(tǒng)要素和產(chǎn)品質(zhì)量的影響。 目前很多學(xué)者在可靠性分析方面已有大量研究成果，但大多僅考慮了加工系統(tǒng)要素方面的因素，而未考慮產(chǎn)品質(zhì)量對各加工系統(tǒng)要素的影響以及相互之間的作用。Chen Y.等提出了“質(zhì)量可靠性交互作用”的理論，建立了多工序加工系統(tǒng)的質(zhì)量可靠性集成模型，有效的描述了多工序加工系統(tǒng)中產(chǎn)品質(zhì)量和加工系統(tǒng)要素可靠性之間的交互作用。但是在Chen Y.等提出的模型中，忽略了要素間的相互影響，沒有考慮系統(tǒng)要素衰退對系統(tǒng)要素故障的影響。 本文擬通過研究系統(tǒng)要素間的相互作用，改進(jìn)了質(zhì)量可靠性交互作用的理論，，完善了多工序加工系統(tǒng)質(zhì)量可靠性集成建模研究。本文通過MATLAB編程，實現(xiàn)了多工序加工系統(tǒng)質(zhì)量可靠性集成建模，并通過蒙特卡洛模擬得到系統(tǒng)可靠性的定量分析。另外，本文以Visual C++6.0為平臺，開發(fā)了“多工序加工系統(tǒng)質(zhì)量可靠性集成預(yù)測系統(tǒng)”，該系統(tǒng)包括“質(zhì)量可靠性分析”、“性能分析”和“過程控制”三個模塊，可對多工序加工系統(tǒng)的可靠性進(jìn)行預(yù)測，并分析系統(tǒng)可靠性對質(zhì)量可靠性交互作用的敏感程度。同時，該系統(tǒng)還可實現(xiàn)在生產(chǎn)周期結(jié)束后對加工系統(tǒng)進(jìn)行靜態(tài)分析和在生產(chǎn)過程中對系統(tǒng)進(jìn)行動態(tài)控制等功能。
[Abstract]:The reliability of processing system is one of the important factors to guarantee product quality and productivity. In the multi-process processing system, the shutdown of the system can be caused by the failure of the system elements or the failure of the product quality, so the reliability of the multi-process processing system should take into account the influence of the system elements and the product quality at the same time. At present, many scholars have done a lot of research on reliability analysis, but most of them only consider the factors of processing system, but not the effect of product quality on the factors of processing system. Chen Y. This paper puts forward the theory of "quality and reliability interaction", establishes the quality reliability integration model of multi-process machining system, and effectively describes the interaction between the product quality and the reliability of machining system elements in the multi-process machining system. But in Chen Y. In the proposed model, the interaction between the elements is neglected, and the effect of the system factor decline on the system element failure is not considered. In this paper, the theory of quality reliability interaction is improved by studying the interaction between system elements, and the integrated modeling of quality reliability of multi-process machining system is improved. In this paper, the integrated modeling of quality reliability of multi-process machining system is realized by MATLAB programming, and the quantitative analysis of system reliability is obtained by Monte Carlo simulation. In addition, based on Visual C 6.0, an integrated quality reliability prediction system for multi-process machining system is developed. The system includes three modules: "quality reliability analysis", "performance analysis" and "process control". The reliability of multi-process machining system can be predicted and the sensitivity of system reliability to the interaction of quality and reliability is analyzed. At the same time, the system can also realize the static analysis of the processing system after the end of the production cycle and the dynamic control of the system in the production process.
