研究人員評估使用「增量化製造」技術生產JSF的部件
本帖最後由 MightyDragon 於 2012-11-22 08:27 AM 編輯舊消息一樣是太讓人興奮 {:4:} 只是一年前澳大利亞的研究人員才評估「增量化製造」技術能不能用於JSF(聯合攻擊戰鬥機，即美國的F-35)上的細小鈦合金部件，一年後中國已經可以使用「增量化製造」技術(即3D打印)造出大型部件，並且有謠言傳出已經用在AMF原型機上。使用「增量化製造」有「快速、省材料」的優點，這將大大加快中國的工業生產過程...

Original Title: Researchers assess additive manufacturing for JSF parts
16 November 2011
Australian researchers are assessing the feasibility of using additive manufacturing to produce small titanium components for the Joint Strike Fighter (JSF).
The research project is a collaboration between RMIT, the Defence Materials Technology Centre (DMTC), Lockheed Martin, 3D Systems, the University of Wollongong and the Defence Science and Technology Organisation (DSTO).
‘Initially we want to find out the effects of various parameters on the microstructure of the built titanium structures and the difference in mechanical properties between vertical and horizontal builds,’ said project lead Prof Milan Brandt from the school of aerospace, mechanical and manufacturing engineering at RMIT. ‘This will then be used to redesign and manufacture the components based on bionic principles.’
An important aspect of the JSF programme is reducing the cost of manufacturing titanium components, which are attractive because of their high strength-to-weight ratio, the ability to retain that strength at high temperatures and high corrosion resistance compared to other alloys.
Prof Brandt said a major problem of manufacturing components from titanium alloys was the high rate of wastage. Technologies that cut waste would significantly impact the cost of manufactured titanium components.
RMIT University academics are looking at the use of selective laser melting (SLM) equipment to make small but expensive titanium-based components.
This method spreads a fine metallic powder in a thin layer typically 50 micrometres thick. A laser beam scans along a path based on the shape of the part to be manufactured, melting the powder and fusing it to the layer below and producing a metallurgical bond between them.
‘At the end of the day it is all leading to manufacturing small-scale JSF titanium components more efficiently and effectively while maintaining their quality and integrity,’ said Brandt.
‘On the fundamental scientific level our objective is to increase the understanding of the SLM process and translate that into practical information for uptake by industry.’...<div class='locked'><em>瀏覽完整內容，請先 <a href='member.php?mod=register'>註冊</a> 或 <a href='javascript:;' onclick="lsSubmit()">登入會員</a></em></div><div></div> 咸魚翻身，還能掉回頭去踢兩腳。 西方這次尷尬了。。 還沒有正式量產出來前
一切都是謠言跟空口號而已 恐怕馬上又有人要說~中國人山寨西方技術了
問題是台灣人_想山寨也山寨不出來啊{:31:} 有些台灣人只會酸中國山寨其他國家的武器
不管黑貓白貓
只要會抓老鼠的貓就是好貓
台灣有本事就山寨 M60A3、Kidd 級驅逐艦、海龍潛艇、F-16 及愛國者
台灣無山寨的能力卻只會酸中國山寨 {:3:} <br><br><br><br><br><div></div> 美國被反咬一口了~
很認同台灣總是說大陸只會製造三債武器卻不會自行研發?
但他們卻萬萬沒想到自己根本沒本事製造
大陸軍事強的原因在於他們敢抄襲敢做! 能研究出來就有希忘量產 穩定物質的品質才是最重要的 外國能發明 中國就有辦法改良 本帖最後由 inmi13137425 於 2012-11-23 06:23 PM 編輯
不知道 什麼講 感覺版主--來源 多事 內地軍事觀察始 我是感覺著台公平性很低
只講 中國最好 起他國家 還在後頭=.= J20 J35 多還搞好...還能不能用 還不知道~.~ 最說 1比200...暈到 我們家的國防部連抄襲都不肯抄襲
說啥對岸做的是爛武器
可是我們買美帝的是玩具
有比較贏喔？？
至少人家肯抄襲肯做咧！ 中路神手 發表於 2012-11-22 04:25 PM static/image/common/back.gif

你這段話好像在講南韓三星集團喔
南韓三星集團一開始也是敢抄襲敢做
等到全部都學完畢了
在來自己創新跟研發...<div class='locked'><em>瀏覽完整內容，請先 <a href='member.php?mod=register'>註冊</a> 或 <a href='javascript:;' onclick="lsSubmit()">登入會員</a></em></div><br><br><br><br><br><div></div> 但是中國增量化技術可靠度令人存疑
尤其又用不成熟的技術作為不成熟技術的基礎 實在是比較有趣的現象
