Chinese mechanical engineering technology not only has a long history and splendid achievements in Chinese is not only the material culture and social economic development plays an important role in the world, and to promote the progress of civilization, technology has made great contribution to Chinese traditional machine. And in a long period ahead in the world. In modern times, especially from the early 18th century, due to the nineteen forties, due to the economic and social reasons, such as the China machinery industry, stagnation, in the 100 years is western bourgeois political revolution and industrial revolution, mechanical science and technology is developing rapidly, and far more than the level of China. So, China mechanical development level and the western gap widens, sharply to the 19th century middle behind western one hundred years.After the founding of new China, especially in the past 30 years, our country's mechanical science and technology development speed. To the mechanical product large-scale, precision, automation and discusses the trend of development. In some aspects has reached or exceeded the world advanced level. Generally speaking, currently China mechanical science and technology achievement is huge, developing fast, high level of unprecedented. In this period, China has no end of mechanical science and technology will develop to a higher level. As long as we can adopt the correct policy, with good technology development and innovation, our machinery industry and mechanical technology can revitalize, leading to the development trend of mechanical industry.Just small ramming machinery:In the 1960s, China mechanical very small tamp lack, many small venues ramming basically USES artificial ramming.Early 1960s, changsha construction machinery institute and Beijing architectural engineering institute, etc., the technical innovation achievements in mass on the basis of summing up Chinese characteristic invented the breaststroke ramming machine, 1962 exceeded national science and technology.

1中國是世界上機械發(fā)展最早的國家之一。中國的機械工程技術(shù)不但歷史悠久，而且成就十分輝煌，不僅對中國的物質(zhì)文化和社會經(jīng)濟(jì)的發(fā)展起到了重要的促進(jìn)作用，而且對世界技術(shù)文明的進(jìn)步做出了重大貢獻(xiàn).傳統(tǒng)機械方面，我國在很長一段時期內(nèi)都領(lǐng)先于世界。到了近代由于特別是從 18 世紀(jì)初到 19 世紀(jì)40 年代，由于經(jīng)濟(jì)社會等諸多原因，我國的機械行業(yè)發(fā)展停滯不前，在這 100多年的時間里正是西方資產(chǎn)階級政治革命和產(chǎn)業(yè)革命時期，機械科學(xué)技術(shù)飛速發(fā)展，遠(yuǎn)遠(yuǎn)超過了中國的水平。這樣，中國機械的發(fā)展水平與西方的差距急劇拉大，到十九世紀(jì)中期已經(jīng)落后西方一百多年。新中國建立后特別是近三十年來，我國的機械科學(xué)技術(shù)發(fā)展速度很快。向機械產(chǎn)品大型化，精密化、自動化和成套化的趨勢發(fā)展。在有些方面已經(jīng)達(dá)到或超過了世界先進(jìn)水平?？偟膩碚f，就目前而言中國機械科學(xué)技術(shù)的成就是巨大的，發(fā)展速度之快，水平之高也是前所未有的。這一時期還沒有結(jié)束，我國的機械科學(xué)技術(shù)還將向更高的水平發(fā)展。只要我們能夠采取正確的方針、政策、用好科技發(fā)展規(guī)律并勇于創(chuàng)新，我國的機械工業(yè)和機械科技一定能夠振興，重新引領(lǐng)世界機械工業(yè)發(fā)展潮流。就小型夯實機械而言：上世紀(jì) 60 年代以前，我國小型夯實機械非常缺乏，很多小型場地的夯實基本上采用人工夯實。上世紀(jì) 60 年代初期，長沙建設(shè)機械研究所與北京建筑工程學(xué)院等單位合作，在群眾性技術(shù)革新成果的基礎(chǔ)上總結(jié)發(fā)明了具有中國特色的蛙式夯實機，1962年獲國家科技發(fā)明獎。蛙式夯實機結(jié)構(gòu)簡單，維修、使用方便，很快成為我國60 年代夯實機械的主導(dǎo)產(chǎn)品。據(jù)不完全統(tǒng)計蛙式夯實機累計產(chǎn)量達(dá)到 50000 多臺，在我國經(jīng)濟(jì)建設(shè)中發(fā)揮了重要作用。70 年代以后，蛙式夯實機逐漸被性能更先進(jìn)的振動沖擊夯和振動平板夯所替代，目前蛙式夯實機已經(jīng)很少，基本被淘汰。1964 年，長沙建設(shè)機械研究所開發(fā)了 HB120 型內(nèi)燃式夯實機，開始由上海工程機械廠生產(chǎn)，后來主要由津市洞庭工程機械廠生產(chǎn)，年產(chǎn)量 200 臺左右。80 年代，內(nèi)燃式夯實機產(chǎn)品質(zhì)量有較大提高，曾出口東南亞和非洲地區(qū)。90 年代以后，內(nèi)燃式夯實機產(chǎn)銷售量也在逐漸減少，目前只有少數(shù)小型民營企業(yè)生產(chǎn)。1977 年，長沙建設(shè)機械研究所和柳州市建筑機械廠開發(fā)了我國第一臺HZR250 型和 HZR70 型振動平板夯，這兩種產(chǎn)品分別于 1979 年和 1982 年通過了由建設(shè)部組織的鑒定。隨后義烏建筑機械廠、四平建筑機械廠、安陽振動器廠、津市洞庭工程機械廠等多家企業(yè)都開始生產(chǎn)振動平板夯。1986 年長沙建設(shè)機械研究所又開發(fā)了較大的 HZR450 型振動平板夯。上世紀(jì) 90 年代以后，振動平板夯在我國有了較快的發(fā)展，產(chǎn)品品種、規(guī)格和生產(chǎn)企業(yè)增多，國外的振動平板夯陸續(xù)進(jìn)入中國市場。1983 年，長沙建設(shè)機械研究所和湖北振動器廠聯(lián)合開發(fā)了我國第一臺HZR70 型振動沖擊夯，1984 年通過了由建設(shè)部組織的鑒定，1985 年獲建設(shè)部科技進(jìn)步三等獎。由于振動沖擊夯具有壓實效果好、生產(chǎn)率高、體積和重量小、輕便靈活等突出特點，深受用戶歡迎，得到了迅速的推廣使用，并很快發(fā)展到資江機器廠、新鄉(xiāng)第三機床廠和津市洞庭工程機械廠等幾十家企業(yè)生產(chǎn)。振動沖擊夯雖然比振動平板夯開發(fā)晚，但發(fā)展速度、產(chǎn)銷量和使用廣泛性比振動平板夯大得多，目前已成為我國夯實機械中產(chǎn)銷量最大的主導(dǎo)產(chǎn)品。上世紀(jì) 90 年代以后，國外的振動平板夯陸續(xù)進(jìn)入中國市場。振動沖擊夯和振動平板夯在我國的成功開發(fā)，不僅為我國建設(shè)施工部門提供了性能先進(jìn)的夯實機械，取得了良好的經(jīng)濟(jì)效益和社會效益，而且使我國夯實機械技術(shù)向前跨進(jìn)了一大步，縮短了與世界先進(jìn)水平的差距，促進(jìn)了我國壓實機械的發(fā)展。就機械加工而言：熱加工 鑄造 據(jù)考古發(fā)現(xiàn)，在北京平谷、昌平、房山等處曾出土了公元前 16 世紀(jì)(商代)的青銅禮器。 明永樂年間(1403～1424 年)，北京制造出享譽世界的明永樂大銅鐘(46.5 噸)和鐘樓大銅鐘(63 噸)及鐵鐘(25 噸)，采用分爐熔化、地坑造型和陶范法鑄造。 20 世紀(jì) 50 年代以前，北京在鑄造上采用粘土砂手工造型。1955 年，北京第一機床廠開始采用漏模造型、雙面模型型板及鐵型板和標(biāo)準(zhǔn)砂箱造型。1965 年，開始采用塑料模型。 1980 年，北京市機電研究院與北京瑪鋼廠研制成功工頻無芯塞桿底注式保溫澆注電爐。1982 年，該院與北京機床鑄造二廠研究成功沖天爐風(fēng)口吹氧技術(shù)。 1985～1988 年，北京機床研究所試驗成功浮動端面密封環(huán)的壓力鑄造工藝。 鍛壓 1959 年，北京第二通用機械廠(后改名北京重型機器廠)建成 2500 噸水壓機。1971 年，該廠制造出 6000 噸水壓機，這是當(dāng)時北京最大的鍛壓設(shè)備。 1968～1979 年，北京起重機器廠先后采用 300 噸油壓機和 2000 噸油壓機制造出起重機吊臂和大型覆蓋件。 80 年代，北京市機電研究院和北京市模具中心研制出一系列高精度多工位沖裁模具，接近或達(dá)到進(jìn)口模具水平，改變了北京精密沖裁模具依賴進(jìn)口的局面。 熱處理 1949 年前，北京已采用電爐、鹽溶爐、熱電偶等手段進(jìn)行零件退火、回火、淬火、正火、調(diào)質(zhì)、滲碳等熱處理。 1956 年，北京第一機床廠開始采用高頻感應(yīng)淬火。1961 年，北京第二機床廠開始采用氣體氮化淬火。1969 年，北京量具刃具廠開始采用光亮淬火。 1978 年，北京機床研究所研究完成機床導(dǎo)軌表面接觸淬火工藝及設(shè)備、淬火質(zhì)量檢查技術(shù)條件的研究。1979 年，鐵道科學(xué)研究院和中國科學(xué)院力學(xué)研究所等合作完成大功率柴油機缸套表面的激光改性處理的研究。 1979 年，北京市機電研究院研制成功千瓦級二氧化碳激光器，并于 80 年代初分別應(yīng)用于汽缸套和郵票印刷設(shè)備的激光熱處理。其中，清華大學(xué)、北京市機電研究院、北京郵票廠共同完成郵票廠七色機打孔器表面激光強化研究。 1984～1990 年，北京市熱處理研究所研究成功真空熱處理、氣體滲碳微機控制技術(shù)(與北京航空航天大學(xué)合作)、稀土軟氮化、粉末冶金制品表面強化、煤油加甲醇小滴量法微機可控滲碳、固體滲硼、滲碳過程微機輔助工藝設(shè)計及跟蹤控制系統(tǒng)等熱處理新技術(shù)，并應(yīng)用于生產(chǎn)。 焊接與切割 1949年，北京已有氣焊、電弧焊及氧乙炔火焰切割等手工作業(yè)。 1963 年，北京金屬結(jié)構(gòu)廠與一機部機械科學(xué)研究院合作開發(fā)出鎢極氬弧焊，并實現(xiàn)了氮氣等離子切割不銹鋼。1964 年，用直流鎢極氬弧焊及焊絲合金化技術(shù)解決了核工業(yè)用傾斜式電解糟純鎳焊接。 1966 年，北京金屬結(jié)構(gòu)廠開發(fā)出了使被焊球體旋轉(zhuǎn)的埋弧自動焊。1968 年，該廠開始以液化石油氣代替乙炔切割。 80 年代初，清華大學(xué)發(fā)明了新型 MIG 焊接電弧控制法，在控制電弧技術(shù)上取得突破。 80年代初，北京城建設(shè)計院等完成液化石油氣移動式氣壓焊軌技術(shù)的研究和應(yīng)用。1990 年，北京金屬結(jié)構(gòu)廠開始采用數(shù)控精密切割和具有光電跟蹤及數(shù)控尋蹤讀入自動編程的大功率等離子切割技術(shù)?？梢?，我國機械發(fā)展在近代發(fā)展其迅速。山西農(nóng)業(yè)大學(xué) 工程技術(shù)學(xué)院畢業(yè)設(shè)計說明書（論文）題目：水力驅(qū)動帶狀噴灌機動力配置方案分析研究作者：蘇亞冰

本文通過對水力驅(qū)動帶狀噴灌機動力配置的分析，進(jìn)行了大量調(diào)查研究，最終得出了兩種動力匹配方案：（一）針對電力較充足的地區(qū)，可利用電動機與柱塞泵相匹配的方案。由于用電便宜，這樣較為經(jīng)濟(jì)。 （二）任何情況下，都可利用農(nóng)用機械上的柴油機與柱塞泵相匹配的方案。對于主要用于噴灌的干旱、半干旱區(qū)農(nóng)村，方案（二）更為合理可行。在農(nóng)村，很多家庭都具有拖拉機、農(nóng)用三輪車、泵和用于噴灑農(nóng)藥或澆水的管道，所以這種動力方案容易被農(nóng)民接受。這個產(chǎn)品的開發(fā)符合中國國情，更能適應(yīng)具有中國特色的農(nóng)村經(jīng)濟(jì)的發(fā)展，有很強的經(jīng)濟(jì)和實用性。本文對研究設(shè)計中需要考慮的一些問題，如泵的擺放與安裝位置，功率匹配等，做了較為詳細(xì)的分析。為新型水力驅(qū)動帶狀噴灌機的研制提供有力的支持。該水力驅(qū)動帶狀噴灌機是節(jié)水噴灌機械和技術(shù)的研究，這種噴灌機械節(jié)水效果好，能用于旱區(qū)丘陵坡地并與田間集雨設(shè)施配套，對旱區(qū)實施節(jié)水旱作、抗旱增產(chǎn)能起到支持作用。這一技術(shù)的應(yīng)用，對占全國耕地面積 50%以上的旱地增產(chǎn)和旱區(qū)農(nóng)民增收，將會發(fā)揮出積極的作用。同時，對灌區(qū)來說，可以實現(xiàn)節(jié)水、節(jié)能、降低生產(chǎn)成本，提高生產(chǎn)效率。面對未來我國人口的不斷增加的形勢，面對人口增加帶來的糧食危機，該技術(shù)的作用都是不可低估的。其帶來的社會效益也將是十分明顯的關(guān)鍵詞 條帶噴灌機 柱塞泵
