【正文】 應(yīng)注意的事項(xiàng) 為了裝配的順利進(jìn)行,符合要求,在建模時(shí)應(yīng)該注意以下事項(xiàng)。 ,局部應(yīng)該先進(jìn)行裝配設(shè)計(jì),再進(jìn)行零件的詳細(xì)設(shè)計(jì)。 ,要嚴(yán)按照裝配設(shè)計(jì)的尺寸來(lái)建模。 ,若發(fā)現(xiàn)干涉情況,應(yīng)仔細(xì)查找原因,如果零件尺寸不符合要求,應(yīng)該重新建立零件數(shù)模。 ,不同的部件再進(jìn)行裝配,可以在早期發(fā)現(xiàn)問(wèn)題,解決問(wèn)題比較方便。 基于逆向工程的電動(dòng)玩具直升飛機(jī)的設(shè)計(jì) 26 總 結(jié) 本課題主要對(duì)電動(dòng)直升飛機(jī)進(jìn)行了逆向設(shè)計(jì),對(duì)飛機(jī)的外形進(jìn)行了改進(jìn)設(shè)計(jì),其使更美觀,對(duì)內(nèi)部結(jié)構(gòu)進(jìn)行了局部?jī)?yōu)化設(shè)計(jì),使結(jié)構(gòu)更趨合理,工藝性較好,同時(shí)對(duì)機(jī)械傳動(dòng)部分進(jìn)行重新設(shè)計(jì)。 通過(guò)本課題,使本人在玩具設(shè)計(jì)方面有一定的進(jìn)步,對(duì)于逆向的基本流程及設(shè)計(jì)要點(diǎn)有了比較深的掌握。對(duì)相關(guān)軟件的應(yīng)用有更深的理解。 應(yīng)用逆向工程進(jìn)行電動(dòng)玩具直升飛機(jī)的設(shè)計(jì),能在較短的設(shè)計(jì)周期內(nèi)完成比較滿意的設(shè)計(jì)。 本人認(rèn)為玩具設(shè) 計(jì),應(yīng)該加強(qiáng)以下幾方面,以期有高品質(zhì)的設(shè)計(jì)。 1. 對(duì)玩具進(jìn)行正向設(shè)計(jì),進(jìn)行創(chuàng)新設(shè)計(jì),應(yīng)該是玩具設(shè)計(jì)的主要的出發(fā)點(diǎn)。 2.由于受學(xué)科水平的限制,本課題所選擇的直升飛機(jī)還是一般型的,要將飛機(jī)做成比較高檔,應(yīng)該需要有更多、更復(fù)雜的運(yùn)動(dòng),如直升飛機(jī)真正在空中的復(fù)雜路線的飛行、飛機(jī)的起降、空中停留,需要有電子學(xué)、計(jì)算機(jī)、流體軟力學(xué)的相關(guān)知識(shí)。 3.對(duì)塑料結(jié)構(gòu)件的設(shè)計(jì),需要有更多的工程背景;對(duì)塑料件的注射過(guò)程進(jìn)行模擬,以分析塑料件結(jié)構(gòu)對(duì)注射工藝的影響,以獲得較好的注射件結(jié)構(gòu)。 4.對(duì)飛機(jī)的運(yùn)動(dòng)進(jìn)行仿真,以獲得更合理、 復(fù)雜的運(yùn)動(dòng)。 5.對(duì)玩具外殼、聯(lián)接進(jìn)行強(qiáng)度的仿真分析,以獲得符合玩具安全標(biāo)準(zhǔn)的設(shè)計(jì)。 6.加強(qiáng)玩具標(biāo)準(zhǔn)的制定與實(shí)施。 南京工業(yè)職業(yè)技術(shù)學(xué)院 畢業(yè)論文 27 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 致 謝 在本次畢業(yè)設(shè)計(jì)的過(guò)程中,校內(nèi)的指導(dǎo)老師王紅軍,給予本人很多幫助和支持,在此表示感謝。其次要感謝校外的指導(dǎo)老師關(guān)紹文先生,是其對(duì)本人的嚴(yán)格要求,比較順利完成本次課題。 感謝母校 南京工業(yè)職業(yè)技術(shù)學(xué)院,為本人提供了良好的學(xué)術(shù)環(huán)境和學(xué)習(xí)氛圍。 最后要感謝的是本人四年的同窗,在資源共享方面給予很大的幫助。 基于逆向工程的電動(dòng)玩具直升飛機(jī)的設(shè)計(jì) 28 參考文獻(xiàn) [1]王林,“中國(guó)玩具發(fā)展 30 年”活動(dòng)跟蹤報(bào)道之五,盤點(diǎn) 2022 中國(guó)玩具產(chǎn)業(yè) 跋涉艱難,期待春天,玩具世界, 2022,1 [2]玩具世界社論,成本質(zhì)量等九大因素制約玩具業(yè)發(fā)展,玩具世界, 2022, 6 [3]楊喜娟,武福,逆向工程及其在工業(yè)設(shè)計(jì)中的應(yīng)用研究,甘肅科技, 2022,11 [4]田濤,陳揚(yáng),史廷春,逆向工程與新產(chǎn)品設(shè)計(jì),河北理工學(xué)院學(xué)報(bào), 2022,11 [5]潘成林,微型電機(jī),廣東:廣東科技出版社, 2022 [6] 王文廣,塑料材料的選用,北京:化工工業(yè)出版社, 2022 [7]劉瑞霞,塑料制品與加工,北京:科學(xué)技術(shù)文獻(xiàn)出版社, 2022 [8]沈世德,機(jī)械原理,北京:機(jī)械工業(yè)出版社, 2022 [9]謝大康,產(chǎn)品模型制作,北京:化工工業(yè)出版社, 2022 [10] 中華人民共和國(guó)輕工行業(yè)標(biāo)準(zhǔn),電動(dòng)玩具通用技術(shù)條件,北京:中國(guó)輕工總會(huì), 1998 [11]中華人民共和國(guó)輕工行業(yè)標(biāo)準(zhǔn),玩具電動(dòng)機(jī),北京:中國(guó)輕工總會(huì), 1998 [12]中華人民共和國(guó)家標(biāo)準(zhǔn),機(jī)動(dòng)玩具機(jī)芯型號(hào)編制方法,北京:國(guó)家標(biāo)準(zhǔn)局, 2022 [13]靳桂芳,機(jī)動(dòng)玩具設(shè)計(jì)原理與實(shí)例,北京: 化學(xué)工業(yè)出版社, 2022 南京工業(yè)職業(yè)技術(shù)學(xué)院 畢業(yè)論文 29 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 裝 ┊ ┊ ┊ ┊ ┊ 訂 ┊ ┊ ┊ ┊ ┊ 線 ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ ┊ 為你提供優(yōu)秀的畢業(yè)論文參考資料,請(qǐng)您刪除以下內(nèi)容, O(∩ _∩ )O 謝謝!?。?A large group of tea merchants on camels and horses from Northwest China39。s Shaanxi province pass through a stop on the ancient Silk Road, Gansu39。s Zhangye city during their journey to Kazakhstan, May 5, 2022. The caravan, consisting of more than 100 camels, three horsedrawn carriages and four support vehicles, started the trip from Jingyang county in Shaanxi on Sept 19, 2022. It will pass through Gansu province and Xinjiang Uygur autonomous region, and finally arrive in Almaty, formerly known as AlmaAta, the largest city in Kazakhstan, and Dungan in Zhambyl province. The trip will cover about 15,000 kilometers and take the caravan more than one year to plete. The caravan is expected to return to Jingyang in March 2022. Then they will e back, carrying specialty products from Kazakhstan A small art troupe founded six decades ago has grown into a household name in the Inner Mongolia autonomous region. In the 1950s, Ulan Muqir Art Troupe was created by nine young musicians, who toured remote villages on horses and performed traditional Mongolian music and dances for nomadic families. The 54yearold was born in Tongliao, in eastern Inner Mongolia and joined the troupe in says there are 74 branch troupes across Inner Mongolia and actors give around 100 shows every year to local nomadic people. I can still recall the days when I toured with the troupe in the early 39。80s. We sat on the back of pickup trucks for hours. The sky was blue, and we couldn39。t help but sing the folk songs, Nasun says. The vastness of Inner Mongolia and the lack of entertainment options for people living there, made their lives lonely. The nomadic people were very excited about our visits, Nasun recalls. We didn39。t have a formal stage. The audience just sat on the grass. Usually, the performances became a big party with local people joining in. For him, the rewarding part about touring isn39。t just about sharing art with nomadic families but also about gaining inspiration for the music and dance. Ulan Muqir literally translates as red burgeon, and today39。s performers of the troupe still tour the region39。s villages and entertain nomadic families, but their fame has spread around the world. On May 16 and 17, nearly 100 singers and dancers from the troupe performed at Beijing39。s Poly Theater. Their show, titled Ulan Muqir on the Grassland, depicted the history and development of the art troupe. Being from the region allowed me to embrace the culture of Inner Mongolia and being a member of the troupe showed me where I belonged, Nasun, the art troupe39。s president, who is also a renowned tenor, tells China Daily. During a tour in 1985, he went to a village and met an elderly local man, who told him a story about his friendship with a solider from Shenyang, capital of Northeast China39。s Liaoning province, decades ago. The solider gave the old man a handmade saddle when they bid farewell. The story inspired Nasun to write Carved Saddle, a song that later became one of his most popular numbers. Now, every year, Nasun recruits young singers and dancers for the troupe. The troupe has also designed a new repertoire, which is mostly based on the daily lives of Mongolian people, especially the lives of nomadic families, and has bined contemporary musical elements with folk songs of the region. Haimu, a 25yearold khoomei (a local variant of overtone singing) singer, joined the troupe three years ago. Along with a sixmember band, he performs fast songs and soft ones that he writes- all while playing the horsehead fiddle.Although I learned the piano since childhood and grew up listening to various ki
