标题:Application of Tailor Heat Treated Blanks technology in a joining by forming process

参考译名:热锻毛坯技术在成形连接中的应用

简介:The usage of modern materials in the automotive industry for the body in white construction leads to increasing requirements for the manufacturing process. Due to the limited formability of high-strength aluminium alloys and steels, joining by forming of these dissimilar materials is still a big challenge, which requires suitable and innovative manufacturing technologies. In sheet forming processes the Tailor Heat Treated Blank (THTB) technology allows enhancing the formability of high-strength aluminium alloys. Therefore, the applicability of the THTB technology for the shear-clinching technology is investigated in this paper. Up till now, this innovative joining by forming technology is only qualified to join ductile aluminium alloys and high-strength steels, but the combination of high-strength aluminium and high-strength steel has not been realized yet. In this research work, the limits of the shear-clinching process have been extended to successfully join the material combinations of AA7075 on the punch side and HCT780X, as well as press hardened 22MnB5 on the die side by using aluminium specimens with different heat treatment layouts. Further, this paper shows the possibility to adjust the material flow of the shear-clinching process by local and short-term heat treatment.

标题:Addressing Uncertainties in Complex Manufacturing Environments: A Multidisciplinary Approach

参考译名:解决复杂制造环境中的不确定性:多学科方法

简介:With the introduction of intelligent and autonomous systems into factory environments, workplaces where human employees work alongside digital counterparts will become increasingly informational. We develop a generic framework for hypothetical workplaces to investigate how complexities create to uncertainties. Complexity may be explained through the Level of Abstractions used to model a system, and it is encountered in its dynamic form as an alteration of information flow between agents in a phenomenological relationship. Analyzing these systems as 'information flows' brings to light the uncertainity(ies) the workers of the future will have to cope with. We develop first concepts that can be used to develop heuristics to manage these uncertainties in complex manufacturing environments. These heuristics may also be useful in creating optimized workplaces that combine the individual abilities of both humans and machines. The framework proposed in this paper may be subject for an empirical validation of these heuristics in the future.

标题:How intelligent scanning could unlock value in smart manufacturing

参考译名:智能扫描如何开启智能制造的价值

简介:It’s unclear exactly what shape the car of tomorrow will take, but one thing seems fairly certain: from a technology standpoint, it will be far more complex and intricate than what we know now—and what we know now is already very complex. Quality and fault checking systems in the manufacturing process will be put under greater strain than before, particularly in the age of autonomous vehicles when automakers are likely to assume greater degrees of a liability should something go wrong on the road.

标题:Multimaterial actinic spatial control 3D and 4D printing

参考译名:多材料光化空间控制3D4D打印

简介:Production of objects with varied mechanical properties is challenging for current manufacturing methods. Additive manufacturing could make these multimaterial objects possible, but methods able to achieve multimaterial control along all three axes of printing are limited. Here we report a multi-wavelength method of vat photopolymerization that provides chemoselective wavelength-control over material composition utilizing multimaterial actinic spatial control (MASC) during additive manufacturing. The multicomponent photoresins include acrylate- and epoxide-based monomers with corresponding radical and cationic initiators. Under long wavelength (visible) irradiation, preferential curing of acrylate components is observed. Under short wavelength (UV) irradiation, a combination of acrylate and epoxide components are incorporated. This enables production of multimaterial parts containing stiff epoxide networks contrasted against soft hydrogels and organogels. Variation in MASC formulation drastically changes the mechanical properties of printed samples. Samples printed using different MASC formulations have spatially-controlled chemical heterogeneity, mechanical anisotropy, and spatially-controlled swelling that facilitates 4D printing.

标题:How Small to Medium Manufacturers Can Compete in the Global Market

参考译名:中小制造商们如何参与全球化市场的竞争

简介:Reshoring is a hot topic in the United States. Politically charged, the practice promises an increase in jobs for workers, profits for manufacturers and a revival of the ‘Made in the United States’ movement. Small- to medium-sized manufacturers can prepare for a manufacturing resurgence, driven by reshoring and regulatory changes. Reshoring is the transferring of a business operation that was moved overseas, back to the country it originated in. In this case, United States manufacturers are bringing their services home from other manufacturing economies, such as Asia. But, what’s driving this change?

标题:波音787工厂曝安全漏洞,员工称不敢搭乘

简介:南卡罗来纳州北查尔斯顿——2009年,波音公司(Boeing)在查尔斯顿附近的新厂破土动工时,曾宣扬这里是最先进的制造中心,将制造一款世界上最先进的飞机。但在接下来的十年里,这家生产787梦想客机的工厂一直受到做工粗糙和监管不力的困扰,危及航空安全。

《纽约时报》查阅了数百页的内部电子邮件、公司文件和联邦记录,并对十几名现任和前任员工进行了采访,揭示出一个经常把速度放在质量之上的文化。面对长期的生产耽搁,波音敦促全体员工高速生产梦想客机,有时无视员工提出的问题。对这种疯狂速度的抱怨,与外界在另一个型号的波音737 Max客机发生两起致命坠机事故之后对公司更广泛的担忧相呼应。波音现在面临的问题包括,为了推出Max机型、赶上竞争对手空中客车(Airbus),是否导致了公司忽视设计上的安全风险,比如在两起坠机事故中都起了作用的防失速系统。

标题:Transfer Analysis of Human Engineering Skills for Adaptive Robotic Additive Manufacturing in the Aerospace Repair and Overhaul Industry

参考译名:航空修理和大修行业自适应机器人增材制造的人类工程技能转移分析

简介:The desire for smart "lights out factories" which can autonomously produce components for high value manufacturing industries is described by the Industry 4.0 solution. This manufacturing methodology is appropriate for newly designed components, which take advantage of modern materials, robotic and automation processes, but not necessarily applicable to overhaul and repair. The aerospace overhaul and repair industry remains heavily dependent on human engineering skills to develop repair and re-manufacturing techniques for complex components of high value. Development of any advanced, intelligent multi-agent robotic additive remanufacturing system requires correct interrogation of metallic materials thermal properties, system control and output. Advanced programming of robots, data interpretation from associated sensory and feedback systems are required to mirror human input. Using process analysis to determine stimuli, replacement of human sensory receptors with electronic sensors, vision systems and high-speed data acquisition and control systems allows for the intelligent fine tuning of multiple heat input parameters to deposit the additive material at any one time. The interaction of these key components combined with novel robotic technology and experienced welding engineers has made possible the construction of a disruptive robotic re-manufacturing technology. This paper demonstrates the design process and analyses the outputs sourced from observation and the recording of highly skilled human engineers when conducting manual remanufacturing and repair techniques. This data is then mined for the transferable control input parameters required to replicate and improve human performance. This industry-academia research intensive collaboration between VBC Instrument Engineering Limited (UK) and The University of Sheffield has received project funding from the Engineering and Physical Sciences Research Council (EPSRC, 2006-2010), the Science and Facilities Technology

标题:Comparative and Exergetic Study of a Gas Turbine System with Inlet Air Cooling

参考译名:带进气冷却的燃气轮机系统的比较性研究

简介:The efficiency of the combined cycle is significantly influenced by the temperature, pressure and humidity of the ambient air. The aim of this study is to investigate the influence of the inlet air cooling system (fogging cooling system) on the gas turbine performance by energy and exergy analyses. Energy and exergy analysis was carried out for nine cases based on the operation data of a gas turbine. Performance parameters include fuel consumption, specific fuel consumption, thermal efficiency, net power output, exergetic efficiency and exergy destruction rates of the components for the cases. It is concluded that the net power output of the gas-turbine system increases at lower inlet air temperatures, and based on the mean values, exergetic efficiency and exergy destruction ratio were found as 37.35% and 33.02%, respectively.

标题:Study suggests some filtering of particulates from diesel exhaust may worsen allergy-induced lung impairment due to increase in NO2

参考译名:研究表明,从柴油尾气中过滤颗粒物可能会加剧因二氧化氮增加引起的过敏性肺损伤

简介:Air pollution from diesel engines may worsen allergy-induced lung impairment more when tiny particles are filtered from the exhaust than when they are not, according to new research published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.This counter-intuitive result may be due to the fact that some particle-depletion technologies, including the one used by the researchers, increase the amount of nitrogen dioxide (NO2) in the exhaust. NO2, which is subject to national air quality standards, has been shown to reduce lung function and may be a cause of asthma in children.

简介:DTF and EDF’s new report, “Impact of Updated Service Life Estimates on Harbor Craft and Switcher Locomotive Emission Forecasts and Cost-Effectiveness”, completed by Ramboll Environ, found the average Category 2 workboat remains in service for 50 years, instead of the 23-year lifespan estimated by the EPA in the 2008 Heavy Duty Locomotive and Marine Rule. A longer service life reduces the fleet’s turnover rate to cleaner, lower-emitting engines, therefore increasing future-year emission estimates.
