EOP子博弈精炼模型在海上无线传感器网络中的应用

随着海上无线传感器网络技术的广泛应用,无线传感器网络在海洋环境监测、海洋环境保护等领域发挥着越来越重要的作用,由于无线传感器网络中节点的能量有限,如何降低网络数据传输能量消耗,延长无线网络寿命,是该领域的研究重点。本文利用博弈论解决无线传感器网络中节点路由选择和冲突平衡的问题,对EOP子博弈精炼模型在海上无线传感器网络中应用的可行性进行研究,提出由簇头选举模型和簇间路由选择模型组成的路由算法。

某客车驱动桥螺旋锥齿轮早期打齿原因分析

针对某客车车桥螺旋锥齿轮崩齿进行失效分析,运用扫描电镜、能谱仪、金相显微镜等分析裂源处的断口形貌、化学成分、金相组织及硬度等,同时结合锥齿轮副的齿面啮合印迹,指出被动锥齿轮断口起裂源处大的Ca和Al的氧化物夹渣,即炼钢过程形成的水口结疤缺陷,是导致其早期失效的主要原因,并提出通过严格控制钢材冶炼过程中炉外精炼、连铸工艺过程等各项工艺参数,严格控制钢材中氧含量不超过15×10^-6等措施,有效防止了该故障发生。     

Recycling of aluminum from fibre metal laminates

Recycling of aluminum alloy scrap obtained from delaminated fibre metal laminates (FMLs) was studied through high temperature refining in the presence of a salt flux. The aluminum alloy scrap contains approximately mass fraction w(Cu) = 4.4%, w(Mg) = 1.1% and w(Mn) = 0.6% (2024 aluminum alloy). The main objective of this research is to obtain a high metal yield, while maintaining its original alloy compositions. The work focuses on the metal yield and quality of recycled Al alloy under different refining conditions. The NaCl-KCl salt system was selected as the major components of flux in the Al alloy recycling. Two different flux compositions were employed at NaCl to KCl mass ratios of 44:56 and 70:30 respectively, based on either the eutectic composition, or the European preference. Different additives were introduced into the NaCl-KCl system to study the effect of flux component on recycling result. Although burning and oxidation loss of the alloying elements during re-melting and refining take place as the drawbacks of conventional refining process, the problems can be solved to a large extent by using an appropriate salt flux. Experimental results indicate that Mg in the alloy gets lost when adding cryolite in the NaCl-KCl salt system, though the metal yield can reach as high as 98%. However, by adding w(MgF₂) = 5% into the NaCl-KCl salt system (instead of using cryolite) all alloying elements were well controlled to its original composition with a metal yield of almost 98%.
