【正文】 我會還十分重視工作制度、工作程序、科學管理和民主辦會，并于 2021 年率先在全國性學會中通過了 ISO9001:2021 質(zhì)量管理體系認證。作為中國機械工程學會在展覽領(lǐng)域的杰作，北京 緊密依靠我會所屬的 “ 北京中機天騰認證咨詢中心 ” ，充分發(fā)揮人才薈萃和組織網(wǎng)絡(luò)的優(yōu)勢，積極開展企業(yè)技術(shù)咨詢、企業(yè)認證咨詢 和發(fā)展戰(zhàn)略咨詢。近年來，又積極推進工程師資格的國際互認。 繼續(xù)教育和專業(yè)人員資格認證是學會服務(wù)社會的有效形式。 會員是學會的主體，是學會存在的基礎(chǔ)和必要條件，是實現(xiàn)學會民主辦會的組織保證。年會包括主旨報告大會、專題學術(shù)會議、科技進 展發(fā)布、論壇、講座、展示、頒獎等多項活動，內(nèi)容豐富，在行業(yè)內(nèi)外乃至全國都產(chǎn)生了巨大影響。 中國機械工程學會成立于 1936 年，是我國成立較早、規(guī)模最大的工科學會之一。 其次，提高行業(yè)準入門檻不失為一個可行的辦法。 任何一個產(chǎn)業(yè)的發(fā)展都離不開市場競爭和政府規(guī)范兩方面的因素。如遼寧鞍山海虹生產(chǎn)的高檔小裝產(chǎn)品不僅擁有自己的專利技術(shù)（利用機械裝置大幅度提升產(chǎn)品性能，避免利用電控、液壓等裝置升級產(chǎn)品性能后給農(nóng)村用戶帶來的使用維護成本上升），而且推出了“無爭議”服務(wù)。 單純依靠價格競爭手段，并不能使小裝行業(yè)得到良性發(fā)展。作業(yè)環(huán)境和使用習慣的不同，導(dǎo)致缺乏非專用配套件的小裝產(chǎn)品根本難以滿足用戶的實際工作需要，增加服務(wù)成本的同時，提高用戶滿意度幾乎成為不可能完成的任務(wù)。 因為小裝產(chǎn)品的用戶以農(nóng)村用戶為主，而能夠覆蓋農(nóng)村用戶的只有農(nóng)機銷售網(wǎng)絡(luò)，建筑機械和工程機械銷售網(wǎng)絡(luò)都只能部分覆蓋農(nóng)村。 至今小裝生產(chǎn)企業(yè)的數(shù) 量是一個“迷”，據(jù)工程機械協(xié)會鏟運分會秘書長陳凱運先生保守估計在 200 家以上。 小裝主要指額定載荷在 ～ 之間的產(chǎn)品，也稱之為微型裝載機。但小裝市場可以說是極速擴張無序競爭并存。 2021 年我國裝載機全行業(yè)總銷售量已突破 3 萬臺，居世界裝載機市場的前列。該標準制訂出來后按當時的行業(yè)分工，柳工、廈工制造 ZL40 以上的大中型輪式裝載機，成工、宜工制造ZL30 以下的中小型輪式裝載機，逐步形成了柳工、廈工、成工和宜工當時的裝載機四大骨干企業(yè)。也基本上代表了我國第一代輪式裝載的基本結(jié)構(gòu)。該機為整體機架、后橋轉(zhuǎn)向。 ADAMS 軟件用于幾種作業(yè)工況的仿真，而PRO/ENGINEER 軟件主要用來建模。s machinery industry is a very important external munication channels, to the industry and the large number of government departments entrusted task of the international exchange and cooperation. Chinese Mechanical Engineering Society of China39。s largest equipment manufacturers licensing system, in terms of production quality suitable restrictions and improve the industry39。s first articulated wheel loader, thus creating our industry loader formation and development history. Z450type loader with hydraulic mechanical transmission, power shift, Shuangqiaoshan drive, hydraulic manipulation, articulated power steering, gas oil Afterburner brake wheel loaders, and other modern, the basic structure of the world39。 外文資料翻譯 學生姓名： 專業(yè)班級： 機械 設(shè)計制造及其自動化 04 級 2班 指導(dǎo)教師： 2021 年 6 月 裝載機發(fā)展概況 Abstract This paper have discussed . ZL50 type forklift truck mainly overall fictitious prototype design as well as some kinds of typical schoolwork operating modes imitate and emulate , include equipment and the overall parts needed build mould. In this design course, have applied ADAMS software and the software of PRO/ENGINEER. ADAMS software is used in the emulation of some kinds of schoolwork operating modes, and the software of PRO/ENGINEER is used to build mould mainly. Through the simulated emulation for some kinds of overall schoolwork operating modes, can see relatively distinctly the overall possible condition in actual schoolwork course that met , can in time modify , have reduced actual design time , have raised production efficiency. The innovation of this design Zhi is in in, imitate and have emulated forklift truck the 3 kinds of typical schoolwork operating mode in actual schoolwork, is effect again have imitated in actual schoolwork the hydraulic impact of use, so when being helpful to solve actual loading, the actual problem of meeting the stock that is hard to uninstall can so raise production efficiency. Key words: Forklift truck 、 fictitious prototype , build mould, emulation, optimization、 production efficiency Loader Development China39。s advanced level for the time . Basically represent the first generation of wheeled loading the basic structure. The aircraft in the overall performance of dynamic, and insertion force a rise of power and flexibility, manipulation of light, the higher operating efficiency of a series of advantages. 1978, Heavenly Creations by the Department in accordance with the requirements of machinery, worked out to LIUGONG Z450based type of wheel loaders series of standards. The development of standards, with reservations Z representatives loaders, L replaced by 4 on behalf of wheel, for ZL50 to Z450, it is so developed a LIUGONG ZL50based China ZLwheel loaders series of standards, this is Wong loader on the development of China39。s manufacturing standards. In recent years loader wellknown enterprises in recent years have involved with the production of small areas, such as the Dragon, XCMG, and the mountains, but not really most of the production of one ton of small equipment products, the main reason is hindering their highend products in the market inadequate capacity. However, this also means that for the small enterprises with not too much time, if not in the relatively short period of time upgrading of enterprises and products, from business philosophy, product marketing idea to the concept of allround selfimprovement, selftransformed into a longterm development objectives and market petitionconscious modern manufacturing enterprises, and a largerscale sales, in the future and wellknown enterprises loader win in the petition may be very small.
