2018-12-05


    [据本站2018年12月5日综合报道]    11月27日,洛克希德•马丁公司在国家训练和仿真协会的跨军种/工业部门训练模拟和教育年度会议上宣布,该公司正在利用增材制造等技术降低F-35联合攻击战斗机全任务训练模拟器的价格,在小批量试生产的11批次合同中,每套模拟器的成本与项目启动初期相比减少了300万美元。

    洛克希德•马丁公司发言人表示,通过实施增材制造等改进的生产技术,该公司今年已实现训练模拟器成本降低25%。模拟器驾驶舱的3D打印将驾驶舱所需部件从800个减少到5个,预计未来五年内将节省1100万美元。此外,自动化技术在F-35训练模拟器生产线上的应用也为降低制造成本发挥了重要作用。

    该公司还将投入3000万美元研究降低模拟器维护成本的方法,并将利用基于新兴威胁的新虚拟培训环境对模拟器进行升级。洛克希德•马丁公司计划到2020年在全球范围内提供约100台训练模拟器,实现在全球范围内对旧F-35模拟器进行升级。洛克希德还将在整个2019年增加新的功能,包括初始分布式任务培训(DMT)、功能和软件模块4培训系统升级。DMT将允许军方在模拟环境中将F-35与F-22或其他第四代战斗机联系起来,有助于开展联合作战训练。(北方科技信息研究所  胡晓睿)

Lockheed Martin Reducing Cost of F-35 Simulator

ORLANDO, Fla. — Lockheed Martin is reducing the price of the F-35 joint strike fighter’s full mission simulators by utilizing technologies such as additive manufacturing.
The cost of the simulators — which has dropped by $3 million per copy since the program’s inception — is reflected in the company’s low-rate initial production lot 11 contract, Lockheed announced Nov. 27 during the National Training and Simulation Association’s annual Interservice/Industry Training Simulation and Education Conference in Orlando.
“Just this year we've been implementing additive manufacturing and some improved production techniques,” said Amy Gowder, Lockheed’s vice president and general manager for training and logistics solutions’ division. “We're taking 25 percent of the cost out of the simulator.”
The effort — which includes 3D printing of the simulator’s cockpits ¬— is projected to save $11 million over the next five years, the company noted. It will reduce components necessary for the cockpit from 800 parts to five, a Lockheed spokesperson said.
It is also improving production techniques by executing long-term supply chain contracts and employing automation on the production line.
The company is also looking at ways to reduce sustainment costs for the simulators and is investing $30 million into the effort, she noted.
It is doing that three ways. One is by “improving the software efficiency and the hardware efficiency from the operating and maintenance cost of the simulators,” Gowder said. Automating support tasks and reducing manpower support requirements will be key.
It is also driving concurrency between the training system and the F-35 aircraft, she said.
“Concurrency with the aircraft is one need I see across all my platforms and all my programs,” she said. “The capabilities are evolving more rapidly and deploying them through agile methods to the aircraft [is necessary]. … The trainer needs to stay in sync so that you can train as soon as the capabilities are ready.”
The simulators will also be upgraded with a new virtual training environment that is based on emerging threats, Gowder added.
Lockheed — which plans to deliver approximately 100 simulators around the world by 2020 — will be able to upgrade older F-35 simulators across the globe with the training environment, she said.
Software upgrades can take as little as a week, she said. Hardware adjustment timelines will be dependent on individual countries schedules and desire to retrofit systems, she added.
Lockheed is also adding capability throughout 2019 including the initial distributed mission training, or DMT, capability and software block 4 training system upgrades. The DMT will allow the military to “link an F-35 with an F-22 or other fourth-gen fighters in a simulated environment with the trainers fighting together,” Gowder said.

克莱姆森大学开发陶瓷激光3D打印技术用于电制氢储能
[据克莱姆森大学网站报道]克莱姆森大学材料科学与工程系正在研究采用一种新的3D打印技术制造“质子陶瓷电解槽堆叠”,将电能转化为氢能。该项研究获得美国能源部能源效率和可再生能源办公室160万美元的资助。
电解槽用途广泛,可用作汽车中的燃料源,也可用于存储太阳能和风能产生的能量。新的激光3D打印技术将减少高度压实电解槽的制造成本和时间。这项新技术不仅可以将制氢成本降低一半,而且还可以将器件尺寸减小一个数量级。该技术可应用于其他类型陶瓷制品的3D打印,包括电池和太阳能电池,或允许智能手机一次充电保持几天的高密度电池。
该项研究最大的挑战之一是如何实现经济高效的陶瓷增材制造。电解槽需要四种不同类型的陶瓷,如果采用传统方法,陶瓷必须在高温炉中烧结数小时,且不同类型的陶瓷需要在不同温度下烧结。研究人员开发出一种3D打印机,在陶瓷铺层的同时进行激光烧结,无需使用熔炉便可打印出由四种不同类型的陶瓷制成的电解槽,这类似于制作具有许多层的蛋糕并且每层具有不同的风味。
克莱姆森大学材料科学与工程系负责人Rajendra Bordia表示,该研究涉及能量转换、激光加工、增材制造、陶瓷材料加工等多个领域,将有助于推动可再生能源转换技术创新取得更大进步。(北方科技信息研究所 胡晓睿)

Lasers could take 3D printing to next level at Clemson University
November 28, 2018
CLEMSON — Cars that go more than 1,000 miles on a single fill-up and smartphones that can run for days without recharging are among the possibilities that could come out of a new Clemson University research project that brings together 3D printing and laser processing.
Jianhua “Joshua” Tong and his team are working on a new 3D-printing technique involving rapid laser processing to create “protonic ceramic electrolyzer stacks” that convert electricity to hydrogen as a way of storing energy.

Jianhua “Joshua” Tong, left, and Ph.D. student Shenglong Mu work in their Sirrine Hall lab, where they are working on new technology that combines 3D printing and laser processing.
The electrolyzers could have several uses, including as a fuel source in cars or to store energy generated from solar and wind power.
The new laser 3D-printing technique would reduce the cost and time of manufacturing highly compacted electrolyzers, Tong said. In doing so, it could not only cut the cost of hydrogen production in half but also decrease device size one order of magnitude, he said.
Tong, an associate professor of materials science and engineering, is leading the research with $1.6 million from the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy.
“Our success will mean we can provide sustainable, clean energy,” Tong said. “That is the fantastic part. We are taking 3D printing to the next level.”
If researchers succeed with the electrolyzers, the same technique could be applied to 3D-printing other types of ceramic products, including batteries and solar cells, Tong said. The technique could, for example, lead to high-density batteries that allow smartphones to maintain a charge for days at a time, he said.
Tong’s project is the latest in a growing body of research aimed at using 3D printing to change how products are manufactured. In 3D printing, products are designed on a computer and then printed one layer at a time, the layers stacking on top of each other to create the product.
The microwave-size 3D printers often found in high school classrooms print with plastic. One of the big challenges in advanced manufacturing is to figure out how to cost-effectively print with other types of materials.
For Tong, the focus is on ceramics.
When made conventionally, ceramics have to be sintered in a furnace at high temperatures, often for several hours. Different types of ceramics need to be sintered at different temperatures.
An electrolyzer requires four different types of ceramics, making the sintering a challenge.
In Tong’s project, a 3D printer puts down a layer of ceramic, and a laser sinters it at the same time, eliminating the need for the furnace.
The technique would allow the user to 3D print an electrolyzer made out of four different types of ceramics without using a furnace. It would be similar to making a cake with many layers and having a different flavor for each layer.
The technique could open 3D printing to new products and all the advantages that come with it. For example, a design for a car’s fuel-cell stack could be emailed to a factory thousands of miles away, and it could be printed within hours rather than waiting for days for delivery, Tong said.
The project brings together four faculty members in Clemson’s Department of Materials Science and Engineering. Tong serves as the principal investigator on the project, while Hai Xiao, Kyle Brinkman and Fei Peng are co-principal investigators.
Rajendra Bordia, chair of the department, said the research enhances Clemson’s efforts to help create more sustainable ways of converting energy.
“The Department of Materials Science and Engineering is uniquely positioned to play a leading role in using electrolysis to create energy for transportation from renewable sources,” he said. “The team working on this project represents world class expertise in relevant areas, including ceramic materials and devices for energy conversion, laser processing, additive manufacturing and ceramic processing.”
Anand Gramopadhye, dean of the College of Engineering, Computing and Applied Sciences, said the project builds on Clemson’s excellence in advanced manufacturing research.
“The amount of the award is a testament to the innovative ideas and top talent that are going into the research,” Gramopadhye said. “I congratulate Dr. Tong and his team on the grant.”

Youbionic adds 3D printed bionic arms to Boston Dynamics robot dog SpotMini
Nov 29, 2018 | By Cameron


Bionics is still in its infancy, and 3D printing has done its part to help pave the way by producing bionichands, eyes, and more. But not all bionics will be directly attached to a person. Italian Youbionic has joined forces with the well-known robotics company Boston Dynamics to meld a pair of bionic arms with the adorable SpotMini.
Youbionic began working on its bionic prosthetic hand in 2014. The company recently released the STL files for their first 3D printable arm and this Humanoid One project is an extension of developing the same architecture. After completing the arm, Youbionic founder Federico Ciccarese moved to the mobility side of the equation as he wants the arms available for use in offices, factories, and homes. “Here I was reminded of the fantastic Boston Dynamic SpotMini that is able to move very well in the environment but has a very limited capacity to manipulate objects due to its single beak,” Federico told 3Ders. “I thought this is a perfect fusion!”
Two arms are certainly better than one, and this will be an informative project because getting the extra weight distributed and balanced correctly will take some work.
The four-legged SpotMini robot is a 25kg robot with 17 joints and the strength to carry a 14kg payload. It is capable of climbing stairs as well as handling objects. SpotMini can already open doors with one arm; imagine the cocktails it’ll be able to make with two hands (plus a bunch of actually productive tasks like assembly and testing of components). Expect to see real pictures and videos next year as Federico reports “I started a collaboration with Actuonix that will provide me with all the actuators I need to assemble Youbionic One. I will do this in 2019 along with the continuation of the whole body.”

His aim is to create assistive devices that interface with their users to increase productivity and fulfillment, and beyond. “The main mission of Youbionic is to develop robotic devices that can be an alter ego of its owner, designed to be controlled as if we were exactly there, that they can get us where we can not get, that they can make us walk on Martian soil, visit planets, navigate space.”
The Mars rovers are evidence that stellar exploration will be heavily dependent upon robotics and bionics, and mobile machines with remotely-controllable arms and limbs will be joining the public in the next few years. The rapid prototyping and complex geometries enabled by 3D printing are helping robotics developers keep to that timeline. One of the big selling points of SpotMini is how non-threatening it is, so whether or not the engineering problems are solved, the success of Centaur Spot may depend on how much the designers can dial up the cuteness and dial back the menacing murderbot look.
