摘要： 機(jī)器是由機(jī)械裝置和其它組件組成的。它是一種用來轉(zhuǎn)換或傳遞能量的裝置，例如：發(fā)動機(jī)、渦輪機(jī)、車輛、起重機(jī)、印刷機(jī)、洗衣機(jī)、照相機(jī)和攝影機(jī)等。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)。術(shù)語中的“機(jī)械裝置設(shè)計(jì)” 的含義要比“機(jī)械設(shè)計(jì)”的含義更為廣泛一些，機(jī)械裝置設(shè)計(jì)包括機(jī)械設(shè)計(jì)。在分析運(yùn)動及設(shè)計(jì)結(jié)構(gòu)時(shí)，要把產(chǎn)品外型以及以后的保養(yǎng)也要考慮在機(jī)械設(shè)計(jì)中。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：開關(guān)、凸輪、閥門、船舶以及攪拌機(jī)等。

設(shè)計(jì)流程
設(shè)計(jì)開始之前就要想到機(jī)器的實(shí)際性，現(xiàn)存的機(jī)器需要在耐用性、效率、重量、速度，或者成本上得到改善。新的機(jī)器必需具有以前機(jī)器所能執(zhí)行的功能。
在設(shè)計(jì)的初始階段，應(yīng)該允許設(shè)計(jì)人員充分發(fā)揮創(chuàng)造性，不要受到任何約束。即使產(chǎn)生了許多不切實(shí)際的想法，也會在設(shè)計(jì)的早期，即在繪制圖紙之前被改正掉。只有這樣，才不致于阻斷創(chuàng)新的思路。通常,還要提出幾套設(shè)計(jì)方案，然后加以比較。很有可能在這個(gè)計(jì)劃最后決定中,使用了某些不在計(jì)劃之內(nèi)的一些設(shè)想。
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。接著還要客觀的分析機(jī)器性能的優(yōu)越性，以及它的安全、重量、耐用性，并且競爭力的成本也要考慮在分析結(jié)果之內(nèi)。每一個(gè)至關(guān)重要的部分要優(yōu)化它的比例和尺寸，同時(shí)也要保持與其它組成部分相協(xié)調(diào)。
也要選擇原材料和處理原材料的方法。通過力學(xué)原理來分析和實(shí)現(xiàn)這些重要的特性，如那些靜態(tài)反應(yīng)的能量和摩擦力的最佳利用，像動力慣性、加速動力和能量；包括彈性材料的強(qiáng)度、應(yīng)力和剛度等材料的物理特性，以及流體潤滑和驅(qū)動器的流體力學(xué)。設(shè)計(jì)的過程是重復(fù)和合作的過程，無論是正式或非正式的進(jìn)行，對設(shè)計(jì)者來說每個(gè)階段都很重要。
Abstract:
A machine is a combination of mechanisms and other components 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.

The Design Process
Designing starts with a need real.Existing apparatus may need improvements in durability, efficiency, weight, speed, or cost. New apparatus may be needed to perform a function previously
done by men, such as computation, assembly, or servicing. With the objective wholly or partly
In 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 comparison. 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 components become apparent, analysis can begin in earnest. The analysis will have as its objective satisfactory or superior performance, plus safety and durability with minimum weight, and a competitive cost. Optimum proportions and dimensions will be sought for each critically
