12、附錄 A 機(jī)械工程的發(fā)展歷程及展望 人類成為 “ 現(xiàn)代人 ” 的標(biāo)志就是制造工具。石器時(shí)代的各種石斧、石錘和木質(zhì)、皮質(zhì)的簡單粗糙的工具是后來出現(xiàn)的機(jī)械的先驅(qū)。從制造簡單工具演進(jìn)到制造由多個(gè)零件、部件組成的現(xiàn)代機(jī)械,經(jīng)歷了漫長的過程。 幾千年前,人類已創(chuàng)制了用于谷物脫殼和粉碎的臼和磨,用來提水的桔槔和轆轤,裝有輪子的車,航行于江河的船及槳、櫓、舵等。所用的動(dòng)力,從人自身的體力,發(fā)展到利用畜力、水力和風(fēng)力。所用材料從天然的石、木、土、皮革,發(fā)展到人造材料。最早的人造材料是陶瓷,制造陶瓷器皿的陶車,已是具有動(dòng)。

14、大連水產(chǎn)學(xué)院畢業(yè)設(shè)計(jì) 中文文獻(xiàn)機(jī)械工程的內(nèi)容機(jī)械工程的服務(wù)領(lǐng)域廣闊而多面,凡是使用機(jī)械、工具,以至能源和材料生產(chǎn)的部門,都需要機(jī)械工程的服務(wù)。概括說來,現(xiàn)代機(jī)械工程有五大服務(wù)領(lǐng)域:研制和提供能量轉(zhuǎn)換機(jī)械、研制和提供用以生產(chǎn)各種產(chǎn)品的機(jī)械、研制和提供從事各種服務(wù)的機(jī)械、研制和提供家庭和個(gè)人生活中應(yīng)用的機(jī)械、研制和提供各種機(jī)械武器。不論服務(wù)于哪一領(lǐng)域,機(jī)械工程的工作內(nèi)容基本相同,主要有:建立和發(fā)展機(jī)械工程的工程理論基礎(chǔ)。例如,研究力和運(yùn)動(dòng)的工程力學(xué)和流體力學(xué);研究金屬和非金屬材料的性能,及其應(yīng)用的工。
15、機(jī)械工程簡介機(jī)械工程是工程學(xué)的一個(gè)分支,它研究機(jī)械和動(dòng)力的產(chǎn)生,尤其是力和運(yùn)動(dòng)。機(jī)械工程的歷史18 世紀(jì)后期,蒸汽機(jī)的發(fā)明為工業(yè)革命提供了一個(gè)主要的動(dòng)力源泉,極大地推動(dòng)了各種機(jī)械的發(fā)展。這樣,一個(gè)新的工程學(xué)的重要分支從民用工程學(xué)中分離出來的關(guān)于工具和機(jī)械的分支發(fā)展了起來。并隨著英國伯明翰機(jī)械工程師協(xié)會(huì)的建立在 1847 年得到了正式承認(rèn)。機(jī)械工程已經(jīng)由一門主要基于試錯(cuò)法的技工應(yīng)用的技藝發(fā)展成為職業(yè)工程師在研究、設(shè)計(jì)和生產(chǎn)領(lǐng)域使用的科學(xué)方法。從最廣義的角度講,增進(jìn)效率的需求不斷地促使機(jī)械工程師提高工作質(zhì)量。
16、信息時(shí)代的機(jī)械工程及工程師在機(jī)械行業(yè)的應(yīng)用在 80 年代初期,工程師們?cè)?jīng)認(rèn)為要加快產(chǎn)品的研制開發(fā),必須進(jìn)行大量的研發(fā)工作。結(jié)果是實(shí)際上只進(jìn)行了較少的研究工作,這是因?yàn)楫a(chǎn)品開發(fā)周期的縮短,促使工程師們盡可能的利用現(xiàn)有的技術(shù)。研制開發(fā)一種創(chuàng)新性的技術(shù)并將其應(yīng)用在新產(chǎn)品上,是有風(fēng)險(xiǎn)的,并且易于招致失敗。在產(chǎn)品開發(fā)過程中采用較少的步驟是一種安全的和易于成功的方法。對(duì)于資金和人力都處于全球性環(huán)境中的工程界而言,縮短產(chǎn)品研制開發(fā)周期也是有益的。能夠設(shè)計(jì)和制造各種產(chǎn)品的人可以在世界各地找到.但是,具有創(chuàng)新思想的人則比較。
