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
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(dòng)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(dòng)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(huì)在設(shè)計(jì)的早期，即在繪制圖紙之前被改正掉。
