星光不問(wèn)趕路人，寧諾博士生二年發(fā)五篇高水平期刊論文

Please scroll down for the English version -UNNC young researcher publishes five high-quality papers in two years.

近日，寧波諾丁漢大學(xué)航空航天工程專業(yè)在讀博士楊悅以第一作者身份在國(guó)際頂級(jí)期刊IJMTM（Inter national Journal of Machine Tools and Manufacture）上發(fā)表了她的最新研究論文。這是她兩年內(nèi)發(fā)表的第五篇論文。

正如研究生院院長(zhǎng)、全球事務(wù)長(zhǎng)張毓�。ˋlain Chong Yee Loong）教授曾在采訪中所表示的，“寧諾的博士生培養(yǎng)方式很靈活，英式的教育體系不強(qiáng)制學(xué)生一定要發(fā)文章才能畢業(yè)。但我們的學(xué)生依然頻頻發(fā)表高水平論文，這源于一種研究的熱情�！�

高精尖人才

辭掉眾人艷羨的工作

本碩畢業(yè)于南京航空航天大學(xué)，研究的是飛行器設(shè)計(jì)，楊悅畢業(yè)后直接進(jìn)入一所飛機(jī)設(shè)計(jì)研究院�？梢哉f(shuō)，她是個(gè)不折不扣的高精尖人才。

“我從小就喜歡數(shù)學(xué)和物理，到了大學(xué)就開(kāi)始研究建�！�，所以剛進(jìn)入飛機(jī)設(shè)計(jì)研究院，被分配到服務(wù)類崗位時(shí)，她急了，不斷找所長(zhǎng)和院長(zhǎng)協(xié)商，一個(gè)月以后才如愿轉(zhuǎn)到了負(fù)責(zé)飛行器的力學(xué)設(shè)計(jì)科研崗位。

工作一年后，她偶然看到了一則寧波諾丁漢大學(xué)博士生獎(jiǎng)學(xué)金信息，抱著試試看的心態(tài)，聯(lián)系了學(xué)校。

“面試我的是李灝楠老師，他跟我談到的關(guān)于先進(jìn)制造領(lǐng)域的前沿研究，讓我非常心動(dòng)�！�

遵從自己的內(nèi)心想法，楊悅辭掉了眾人艷羨的工作，走進(jìn)了寧諾的學(xué)堂。

楊悅記得剛開(kāi)學(xué)的那段日子，導(dǎo)師Dragos Axinte每周都和她開(kāi)會(huì)，督促她匯報(bào)研究進(jìn)度，使得她只能天天呆在實(shí)驗(yàn)室，一個(gè)月以后才開(kāi)始整理宿舍的行李。但也正是這種嚴(yán)格的鍛煉，楊悅走出了自己的舒適圈，從一個(gè)實(shí)驗(yàn)“小白”進(jìn)階成一個(gè)專業(yè)實(shí)驗(yàn)人員。

除此之外，楊悅提到，她的二導(dǎo)李灝楠幾乎全程陪著大家，讓他們用最短的時(shí)間進(jìn)入學(xué)習(xí)生活狀態(tài)，三導(dǎo)廖智榮老師 “在做實(shí)驗(yàn)時(shí)遇到困難，無(wú)論幾點(diǎn)給他打電話，只要看到了就會(huì)回”，這些點(diǎn)滴都讓她無(wú)悔當(dāng)時(shí)的選擇。

“剛?cè)岵��?jì)”

一舉破解領(lǐng)域內(nèi)難題

寧波諾丁漢大學(xué)李達(dá)三首席教授、制造領(lǐng)域國(guó)際頂尖專家Dragos Axinte在談到楊悅時(shí)說(shuō)，每年他都會(huì)給新入學(xué)的博士生布置制造領(lǐng)域的難題，但有一題已經(jīng)三年沒(méi)有人能解答出來(lái)了。讓他沒(méi)想到的是，楊悅只花了三個(gè)月就成功解出并據(jù)此寫了一篇論文。

這道難題源于實(shí)際生產(chǎn)加工，研磨盤在拋光套筒中的工件時(shí)表面光滑度總是欠缺。此前針對(duì)這個(gè)問(wèn)題的研究都聚焦于優(yōu)化轉(zhuǎn)速設(shè)定，忽視了套筒和工件之間的間隙，楊悅希望通過(guò)從這方面著手搞清楚產(chǎn)生這種偏差的原因。

為了觀察工件在套筒內(nèi)的的運(yùn)動(dòng)軌跡，楊悅從早到晚都呆在實(shí)驗(yàn)室，每天思考著不同的方法，反復(fù)的實(shí)驗(yàn)均以失敗告終。就在她感到崩潰的時(shí)候，桌面的馬克筆讓她靈光一現(xiàn)。她用馬克筆涂抹工件，觀察劃痕，最終實(shí)驗(yàn)成功。

這項(xiàng)有關(guān)剛性磨具的研究于去年發(fā)表在英國(guó)皇家期刊Proceedings of Royal Society上。Dragos Axinte前不久還在CIRP國(guó)際會(huì)議上向?qū)W術(shù)界推薦了這項(xiàng)研究。通過(guò)揭示工件在套筒中的運(yùn)動(dòng)規(guī)律，該研究使得更多研究者關(guān)注到間隙問(wèn)題，有望從根本上提高工件表面加工質(zhì)量。

而楊悅最新發(fā)表的文章則聚焦柔性磨具，是學(xué)界起步不久的前沿研究。柔性磨頭可以精密加工平面和曲面（如攝像頭、人造關(guān)節(jié)），在精密制造領(lǐng)域應(yīng)用前景十分廣闊。

這篇文章的發(fā)表是與日本京都大學(xué)和業(yè)界zeeko公司共同合作的成果，前者擁有全球領(lǐng)先的實(shí)驗(yàn)室和雄厚的科研實(shí)力，后者則為超精密磨拋領(lǐng)域世界領(lǐng)先企業(yè)。她說(shuō)，能與這些頂尖院校企業(yè)合作，離不開(kāi)英國(guó)諾丁漢大學(xué)先進(jìn)制造實(shí)驗(yàn)室的“全球朋友圈”。

據(jù)悉，目前為止，楊悅一共發(fā)表了五篇國(guó)際期刊論文，均發(fā)表在制造工程學(xué)科世界前25%期刊上。在柔性磨頭領(lǐng)域，她分別以一作和二作身份各發(fā)表了一篇研究。未來(lái)她會(huì)繼續(xù)關(guān)注柔性拋光頭，并與產(chǎn)業(yè)界開(kāi)展進(jìn)一步的合作。

UNNC young researcher publishes five high-quality papers in two years

Recently, a PhD student of the University of Nottingham Ningbo China (UNNC), Yue (Yolanda) Yang published a paper in one of the world’s top journals on manufacturing - International Journal of Machine Tools and Manufacture.

The paper, entitled “Controlling of compliant grinding for low-rigidity components”, is Yolanda’s brainchild. In her paper, she proposes a solution to address the accuracy challenge in machining, when both the workpiece and tool are compliant in grinding.

With thin-walled structures being applied increasingly widely in engineering construction, many areas now face this practical problem, such as aerospace and automotive industries. The controlling method that Yolanda has presented in her paper enables, for the first time, to obtain the desired and uniform material removal rate, helping manufacturers to improve the machining precision and produce higher quality components.

This paper is the fifth that Yolanda has published since her admission to UNNC as a PhD student two years ago. All her five papers are devoted to advanced manufacturing and published in highly ranked journals categorised as JCR Q1, which denotes the top 25% of journals according to Journal Citation Reports.

A prolific young researcher as she is, Yolanda didn’t have much experience in manufacturing engineering before joining UNNC. In her undergraduate and master’s degree study, Yolanda majored in aircraft design and spent one year subsequently working in a well-established research institute.

“But it is UNNC that gives me a world of possibilities and allows me to be the best I can be.” She said.

After an online chat withDr Haonan Li, who is now one of her supervisors, Yolanda decided to pursue a doctoral study at UNNC onadvanced and intelligent manufacturing.

“I was challenged by a test that Dr Haonan Li sent to me. I found it very interesting and that test inspired my interest in advanced manufacturing.” Yolanda said. “Dr Li gave me a strong support during my PhD application.”

Yolanda’s supervisors also includeChair Professor Dragos AxinteandDr Zhirong Liaoat the University of Nottingham UK campus.

Professor Dragos Axinte speaks highly of Yolanda: “She is a very talented student. She has a solid foundation in scientific knowledge and is hardworking,” Professor Axinte said. “Whatever problem you throw to her, she picks it up and solves it! I gave her a manufacture problem that other students had struggled with for over three years, and believe it or not, she solved it in three months.”

The “problem” that Professor Axinte gave to Yolanda dealt with an issue in the manufacturing process. Resolving it required both mathematical modelling and simulation validation. Yolanda was confident in providing the model, but she encountered a challenge in the simulation test. After having rounds of discussions with her supervisors and spending long hours in the lab, eventually, she found the solution.

Her result was published in the journal - Proceedings of the Royal Society A, titled “A curious observation of phenomena occurring during lapping/polishing processes”.

Yolanda was grateful to her supervisors. “I have been good at solving physics, mathematics and modelling problems, but wasn’t very comfortable with lab experiments,” she says. “With the support and guidance from my supervisors, I walked out of my comfort zone and became well capable of it. Without any one of them, I won’t be able to achieve so much.”

As part of her PhD programme, Yolanda is now at the University of Nottingham UK campus, sponsored by China Scholarship Council (CSC) for two years, to further her research on advanced and intelligent manufacturing.
