The clay mineral composition is one of the major factors that governs the physical properties of silty sand subgrade. Therefore, a thorough knowledge of mineral composition is essential to predict the optimum engineering properties of the soil, which is generally characterized by different indices like maximum dry density (MDD), California bearing ratio (CBR), unconfined compressive strength (UCS) and free swelling index (FSI). In this article, a novel multi-attribute decision making (MADM) based approach of mix design has been proposed for silty sand – artificial clay mix to improve the characteristic strength of a soil subgrade. Experimental investigation has been carried out in this study to illustrate the proposed approach of selecting appropriate proportion for the soil mix to optimize all the above mentioned engineering properties simultaneously. The results show that a mix proportion containing approximately 90% silty sand plus 10% bentonite soil is the optimal combination in context to the present study. The proposed methodology for optimal decision making to choose appropriate combination of bentonite and silty sand is general in nature and therefore, it can be extended to other problems of selecting mineral compositions.

A new pipe rupture valve for hydraulic elevator is designed. Mathematical models established for the hydraulic elevator system are used in numerical simulations on the Simulink environment of Matlab kits. The effects of different viscous damping diameters, inlet pressures of pipe rupture valve, and elevator loads on the hydraulic elevator system s dynamic performance are analyzed. Experimental research is also carried out using a hydraulic elevator experiment rig. The numerical simulations accord with experimental results in general. Dynamic performance indexes are assessed by the EN81-2 standard. The results show that the newly designed pipe rupture valve meets the designing requirement for hydraulic elevators.

自动化和数字化方面的最新进展使得物理设备与其对应的虚拟设备紧密集成,从而促进了实时建模与多个过程的自动优化。此类系统提供了丰富且不断更新的数据环境,使得系统随着时间的推移做出决策,并将过程推向最优目标成为可能。在许多制造过程中,为了实现整体最优过程,必须同时评估与过程性能和成本有关的多个目标函数。本文提出了一个多目标最优实验设计框架,用于提高在线模型识别平台的效率。所提出的框架能够灵活权衡实验设计解决方案,这些解决方案可以在线计算(即在执行实验期间)。将该框架应用于流动反应器中动力学模型在线识别的案例研究,并确定了微反应器中苯甲酸(benzoic acid, BA)和乙醇酯化的动力学模型。

应用正交设计优化煤层注水工艺参数的组合,对地质条件稳定的煤层是实现最佳注水效果的一种较好的方法。但是,对于地质条件不断变化的煤层,采用该方法,其效果不一定能满足注水工程要求。为此,针对地质因素为不稳定状态下的煤层及影响煤层注水的地质因素既有定性变量又有定量变量的特征,提出利用数量化理论与正交设计2种方法确定注水工艺参数的最优组合,并进行了工程试验优化研究。试验结果表明,此法节省注水试验工程量,接近实际工程要求。

Stiffness can be considered of primary importance in order to guarantee the successful use of any robotic system for a given task. Therefore, this paper proposes procedures for carrying out both numerical and experimental estimations of stiffness performance for multibody robotic systems. The proposed numerical procedure is based on models with lumped parameters for deriving the Cartesian stiffness matrix. Stiffness performance indices are also proposed for comparing stiffness performance. Then, an experimental procedure for the evaluation stiffness performance is proposed as based on a new measuring system named as Milli-CATRASYS (Milli Cassino Tracking System) and on a trilateration technique. Cases of study are reported to show the soundness and engineering feasibility of both the proposed numerical formulation for stiffness analysis and experimental validation of stiffness performance.
