【正文】 工作,即在新產(chǎn)品設(shè)計之初,就把“機械”與“電子”統(tǒng)一起來進行考慮,使“機械”與“電子”密不可分,深度結(jié)合,生產(chǎn)出來的新產(chǎn)品起碼正做到機電一體化。要注意抓兩個層次上的工作。增大支持力度,在技術(shù)政策上,要嚴(yán)格限制耗電、耗水、耗材高的傳統(tǒng)產(chǎn)品的發(fā)展,對未采用機電一體化技術(shù)落后產(chǎn)品限制強制淘汰;大力提倡用機電一體化技術(shù)對傳統(tǒng)產(chǎn)業(yè)進行改造,對有關(guān)機電一體化技術(shù)對傳統(tǒng)產(chǎn)業(yè)乾地改造,對有關(guān)技術(shù)開發(fā)、應(yīng)用項目優(yōu)先立項、優(yōu)先支持,對在技術(shù)開發(fā)、應(yīng)用中做出貢獻的單位領(lǐng)導(dǎo)、科技人員進行表彰獎勵等。因此,我國有必要明確一個“機電一體化”行業(yè)的統(tǒng)管機構(gòu),根據(jù)目前國家政治體制改革和經(jīng)濟體制改革的精神,以及機電一體化行業(yè)特點,我們建議,盡快加強北京機電一體化協(xié)會的建設(shè),賦予其行業(yè)管理職能。各單位的計劃由于受各自立足點、著眼點的限制,難免只考慮局部利益,各主管部門的有關(guān)計劃和規(guī)劃,也有統(tǒng)一考慮不足,統(tǒng)籌安排不夠的問題,同時缺少綜觀全局的有權(quán)威性的發(fā)展計劃和戰(zhàn)略規(guī)劃。四、我國發(fā)展“機電一體化”的對策(一)加強統(tǒng)籌安排,協(xié)調(diào)發(fā)展計劃目前,我國從事“機電一體化”研究開發(fā)及生產(chǎn)的單位很多??偟哪康氖谴龠M機電一體產(chǎn)業(yè)的形成、為我國產(chǎn)業(yè)結(jié)構(gòu)和產(chǎn)品結(jié)構(gòu)調(diào)整作貢獻。另外,從市場需求的角度看,由于我國研制、開發(fā)機電一體化產(chǎn)品的歷史不長,差距較大,許多產(chǎn)品的品種、數(shù)量、檔次、質(zhì)量都不能滿足需求,每年進口量都比較大,因此亟需發(fā)展。這是解決機電產(chǎn)品多品種、少批量生產(chǎn)的重要出路。上佳的答案早就擺在了這些企業(yè)的面前,這就是發(fā)展機電一體化,開發(fā)和生產(chǎn)有關(guān)的機電一體化產(chǎn)品。近年來我國的工業(yè)結(jié)構(gòu)、產(chǎn)品結(jié)構(gòu)雖然幾經(jīng)調(diào)整,但由于多種原因,成效一直不夠明顯。3. 我國用機電一體化產(chǎn)品取代技術(shù)含量和附加值低,耗能、耗水、耗材高,污染、擾民產(chǎn)品的責(zé)任重,有意義。三、我國發(fā)展“機電一體化”面臨的形勢和任務(wù)機電一體化工作主要包括兩個層次:一是用微電子技術(shù)改造傳統(tǒng)產(chǎn)業(yè),其目的是節(jié)能、節(jié)材,提高工效,提高產(chǎn)品質(zhì)量,把傳統(tǒng)工業(yè)的技術(shù)進步提高一步;二是開發(fā)自動化、數(shù)字化、智能化機電產(chǎn)品,促進產(chǎn)品的更新?lián)Q代。典型的機電一體化元、部件有:電力電子器件及裝置、可編程序控制器、模糊控制器、微型電機、傳感器、專用集成電路、伺服機構(gòu)等。二、典型的機電一體化產(chǎn)品機電一體化產(chǎn)品分系統(tǒng)(整機)和基礎(chǔ)元、部件兩大類。屆時機械和電子完全可以“融合”,機體、執(zhí)行機構(gòu)、傳感器、CPU等可集成在一起,體積很小,并組成一種自律元件。目前,利用半導(dǎo)體器件制造過程中的蝕刻技術(shù),在實驗室中已制造出亞微米級的機械元件。看來,機電一體化產(chǎn)品雖然有向生物系統(tǒng)化發(fā)展趨,但有一段漫長的道路要走。仿生學(xué)研究領(lǐng)域中已發(fā)現(xiàn)的一些生物體優(yōu)良的機構(gòu)可為機電一體化產(chǎn)品提供新型機體,但如何使這些新型機體具有活的“生命”還有待于深入研究。今后的機電一體化裝置對信息的依賴性很大,并且往往在結(jié)構(gòu)上是處于“靜態(tài)”時不穩(wěn)定,但在動態(tài)(工作)時卻是穩(wěn)定的。除此之外,其系統(tǒng)的層次結(jié)構(gòu),也變簡單的“從上到下”的形勢而為復(fù)雜的、有較多冗余度的雙向聯(lián)系。今后的機電一體化產(chǎn)品“全息”特征越來越明顯,智能化水平越來越高。這樣,既明顯地增加了系統(tǒng)的適應(yīng)能力(柔性),又不因某一子系統(tǒng)的故障而影響整個系統(tǒng)。在自律分配系統(tǒng)中,各個子系統(tǒng)是相互獨立工作的,子系統(tǒng)為總系統(tǒng)服務(wù),同時具有本身的“自律性”,可根據(jù)不同的環(huán)境條件作出不同反應(yīng)。 、電力電子等的發(fā)展為機電一體化提供了堅強基礎(chǔ)。39。 strongly advocated using electromechanical integration on the traditional industries for the transformation of the electrical and mechanical integration technology to transform traditional industries dry on the technical development and application of project priority projects, and give priority support to the technical development and application of the unit to contribute to leadership, science and technology personnel of recognition incentives. (D) to highlight key development, take into account the two levels Mechatronics industries cover a very wide, and our financial, human and material resources are limited, so we grasp mechatronics industry development can not be exhaustive, Bengpuzhixu, it should distinguish between primary and secondary, bold choices, in order, selective. Attention should be paid to work on two levels. The first level is the face of work, namely the use of electronic information technology to transform traditional industries, in the traditional electromechanical devices implanted or grafted on Microelectronics (puter) devices, the machinery and electronic technology in the Jiancengci integrate. The second level is the increase, that is the beginning of the new product design, they machinery and electronic unified consideration, machinery and electronic inextricably linked, indepth integration of the new production Products are at least do electromechanical integration. CONCLUSION: In this paper, in the careful guidance of teachers and strict requirements have been pleted. Learning and life, will always feel the careful guidance of a mentor and selfless caring, I benefited. You are here to express our deep gratitude and lofty respect. Why not plot to跬step of a thousand miles, the smooth pletion of the design, but also owe much to the datum related to the serious and responsible teacher, I can well understand and use our professional knowledge, and to be reflected in the design. At the same time, I collected a lot of online information before making my dissertation work smoothly. College of Engineering here to all teachers expressed heartfelt thanks.一、機電一體化技術(shù)發(fā)展歷程及其趨勢自電子技術(shù)一問世,電子技術(shù)與機械技術(shù)的結(jié)合就開始了,只是出現(xiàn)了半導(dǎo)體集成電路,尤其是出現(xiàn)了以微處理器為代表的大規(guī)模集成電路以后,機電一體化技術(shù)之后有了明顯進展,引起了人們的廣泛注意.(一)機電一體化的發(fā)展歷程,寫下了機電一體化歷史的第一頁。 guidance layout layout of the industry adjustment, the starting point for the development of options, do a good job of the pilot and key projects of the issuing of the project, the tender exercise…… (C) Optimization development environment, increased support for the Optimization development environment that through propaganda among the masses, creating a munity as a whole, both inside and outside the enterprise to support the mechanical and electrical integration, the atmosphere of development, such as China as soon as possible for foreign investors to invest in the development of mechatronics industry to provide convenient as possible for the establishment of development, production integration of mechanical and electri
