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： 機器是由機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、渦輪機、車輛、起重機、印刷機、洗衣機、照相機和攝影機等。許多原則和設(shè)計方法不但適用于機器的設(shè)計，也適用于非機器的設(shè)計。術(shù)語中的“機械裝置設(shè)計” 的含義要比“機械設(shè)計”的含義更為廣泛一些，機械裝置設(shè)計包括機械設(shè)計。在分析運動及設(shè)計結(jié)構(gòu)時，要把產(chǎn)品外型以及以后的保養(yǎng)也要考慮在機械設(shè)計中。在機械工程領(lǐng)域中，以及其它工程領(lǐng)域中，所有這些都需要機械設(shè)備，比如：開關(guān)、凸輪、閥門、船舶以及攪拌機等。

設(shè)計流程
設(shè)計開始之前就要想到機器的實際性，現(xiàn)存的機器需要在耐用性、效率、重量、速度，或者成本上得到改善。新的機器必需具有以前機器所能執(zhí)行的功能。
在設(shè)計的初始階段，應(yīng)該允許設(shè)計人員充分發(fā)揮創(chuàng)造性，不要受到任何約束。即使產(chǎn)生了許多不切實際的想法，也會在設(shè)計的早期，即在繪制圖紙之前被改正掉。
