阀口独立电液控制系统通过电子化反馈与复杂进出口独立控制策略提高系统智能化水平,但高安全风险也制约了其大规模市场化应用。为此,提出一种面向ISO 13849机器安全标准的阀口独立控制系统安全性能评估方法。针对阀口独立控制系统特有的多自由度控制、多变量反馈、多模式切换特点,结合故障树分析法和布尔代数运算建立系统四象限工况安全性模型,构建该模型至ISO13849中预定义安全结构类别的映射,推导系统安全性能等级PL值及其每小时发生引起危险的停机故障概率(PFHd)的量化方法。考虑常规控制、故障诊断与主动容错控制器三类控制方法,分析系统安全结构由类型1单通道至类型3双通道的变换。评估结果表明,系统PL仅为b级,难以满足移动机器d级要求;引入故障诊断后,PL仅提高至c级;增加故障主动容错后,不增加额外硬件冗余情况下PL可增加至d级甚至最高e级。研究工作为智能化电液系统控制、诊断、容错设计构建遵循机器功能安全的评估与指导。

Coherent systems are very important in reliability, survival analysis and other life sciences. In this paper, we consider the number of failed components in an(n-k + 1)-out-of-n system, given that at least m(m < k ≤ n) components have failed before time t, and the system is still working at time t. In this case, we compute the probability that there are exactly i working components. First the reliability and several stochastic properties are obtained. Furthermore,we extend the results to general coherent systems with absolutely continuous and exchangeable components.

Selective separation of CO_(2) and H_(2)S from CH_(4) is of importance to the natural gas upgrading because of its cor-rosivity. As is well known, amine group can recognize reversibly CO_(2) and H_(2)S with a moderate interaction. Withthis in mind, this work prepared a series of amine-functionalized supported-protic-ionic-liquid membranes(SPILMs) for the selective separation of CO_(2) and H_(2)S from CH_(4) . For comparison, aprotic ionic liquid membranewas also prepared for natural gas sweetening. The effect of temperature and transmembrane pressure differenceon the permeability of single gas and ideal selectivity of CO_(2)/CH_(4) and H_(2)S/CO_(2) were studied. Facilitated transportmechanism was studied by NMR spectra. The permeability of CO_(2) in primary amine functionalized [DMPDAH][Tf_(2)N]-based membrane decreases with the increasing transmembrane pressure, indicating a typical feature offacilitated transport membrane. The permeability of CO_(2) and the ideal selective of CO_(2)/CH_(4) are as high as 2000 barrers and 53.2 at 313.2 K in [DMPDAH][Tf_(2)N] membrane, significantly higher than those in conventional ILsmembrane. It is anticipated that these amine-functionalized SPILMs can provide alternative insight for the se-lective separation of CO_(2) and H_(2)S from CH_(4) .
