機(jī)械類-機(jī)械設(shè)計(jì)-外文翻譯-機(jī)械設(shè)計(jì)(完整版)
【正文】 logy has the deep elementary knowledge. One of the first steps in the design of any product is to select the material from which each part is to be made. Numerous materials are available to today39。新設(shè)計(jì)本身會(huì)有許多缺陷和未能預(yù)料的問(wèn)題發(fā)生，只有當(dāng)這些缺陷和問(wèn)題被解決之后，才能體現(xiàn)出新產(chǎn)品的優(yōu)越性。僅僅使用數(shù)據(jù)和公式是不足以在一個(gè)好的設(shè)計(jì)中做出所需的全部決定的。另一個(gè)重要問(wèn)題，設(shè)計(jì)工程師必須能夠同其他有關(guān)人員進(jìn)行交流和磋商。計(jì)算（圖紙尺寸）檢查是非常重要的。機(jī)械設(shè)計(jì)是一項(xiàng)創(chuàng)造性的工作。5. 介紹疲勞失效理論并強(qiáng)調(diào)在壓力條件下接近高循環(huán)的疲勞設(shè)計(jì)，這通常用在旋轉(zhuǎn)機(jī)械的設(shè)計(jì)中。7. 選擇組合材料。為了激發(fā)創(chuàng)造性思維，下列是設(shè)計(jì)和分析的建議規(guī)則。在近年來(lái)的許多產(chǎn)品責(zé)任訴訟案件中，由于錯(cuò)誤地使用產(chǎn)品而受到傷害的原告控告生產(chǎn)廠家，并且贏得判決）；(c)所使用的材料的數(shù)據(jù)不全或是有些數(shù)據(jù)不確定，尤其是當(dāng)其性能數(shù)據(jù)長(zhǎng)期不更新；(d)質(zhì)量控制方法不適當(dāng)和未經(jīng)驗(yàn)證；(e)由一些完全不稱職的人員選擇材料。設(shè)計(jì)的過(guò)程是重復(fù)和合作的過(guò)程，無(wú)論是正式或非正式的進(jìn)行，對(duì)設(shè)計(jì)者來(lái)說(shuō)每個(gè)階段都很重要。只有這樣，才不致于阻斷創(chuàng)新的思路。許多原則和設(shè)計(jì)方法不但適用于機(jī)器的設(shè)計(jì)，也適用于非機(jī)器的設(shè)計(jì)。在機(jī)械工程領(lǐng)域中，以及其它工程領(lǐng)域中，所有這些都需要機(jī)械設(shè)備，比如：開(kāi)關(guān)、凸輪、閥門、船舶以及攪拌機(jī)等。一般的當(dāng)外型特點(diǎn)和組件部分的尺寸特點(diǎn)分析得透徹時(shí)，就可以全面的設(shè)計(jì)和分析。產(chǎn)品的設(shè)計(jì)需要不斷探索和發(fā)展。盡管采用最好的材料選擇方法也不能避免發(fā)生產(chǎn)品責(zé)任訴訟，設(shè)計(jì)人員和工業(yè)界按照適當(dāng)?shù)某绦蜻M(jìn)行材料選擇，可以大大減少訴訟的數(shù)量。2. 認(rèn)識(shí)負(fù)載產(chǎn)生的影響及其意義。10. 規(guī)定好準(zhǔn)確的位置條件為了使組件安裝時(shí)不干涉。8. 討論潤(rùn)滑油膜與滾動(dòng)軸承的理論和應(yīng)用。許多的材料被今天的設(shè)計(jì)師所使用。計(jì)算機(jī)是一種工具，它能夠幫助機(jī)械設(shè)計(jì)師減輕繁瑣的計(jì)算，并對(duì)現(xiàn)有數(shù)據(jù)提供進(jìn)一步的分析。如前所訴，機(jī)械設(shè)計(jì)的目的是生產(chǎn)能夠滿足人類需求的產(chǎn)品。一個(gè)好的設(shè)計(jì)人員應(yīng)該勇于提出新的想法，而且愿意承擔(dān)一定的風(fēng)險(xiǎn)，當(dāng)新的方法不適用時(shí)，就使用原來(lái)的方法。外文原文（復(fù)印件）Mechanical DesignAbstract:A machine is a bination of mechanisms and other ponents which transforms, transmits. Examples are engines, turbines, vehicles, hoists, printing presses, washing machines, and movie cameras. Many of the principles and methods of design that apply to machines also apply to manufactured articles that are not true machines. The term mechanical design is used in a broader sense than machine design to include their design. the motion and structural aspects and the provisions for retention and enclosure are considerations in mechanical design. Applications occur in the field of mechanical engineering, and in other engineering fields as well, all of which require mechanical devices, such as switches, cams, valves, vessels, and mixers.Keywords: Mechanical Design mechanisms Design ProcessThe Design ProcessDesigning starts with a need apparatus may need improvements in durability, efficiency, weight, speed, or cost. New apparatus may be needed to perform a function previouslydone by men, such as putation, assembly, or servicing. With the objective wholly or partlyIn the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint. Even if has had many impractical ideas, also can in the design early time, namely in front of the plan blueprint is corrected. Only then, only then does not send to stops up the innovation the mentality. Usually, must propose several sets of design proposals, then perform the parison. Has the possibility very much in the plan which finally designated, has used certain not in plan some ideas which accepts.When the general shape and a few dimensions of the several ponents bee apparent, analysis can begin in earnest. The analysis will have as its objective satisfactory or superior performance, plus safety and durability with
