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。許多原則和設計方法不但適用于機器的設計，也適用于非機器的設計。術語中的“機械裝置設計” 的含義要比“機械設計”的含義更為廣泛一些，機械裝置設計包括機械設計。在分析運動及設計結構時，要把產品外型以及以后的保養(yǎng)也要考慮在機械設計中。在機械工程領域中，以及其它工程領域中，所有這些都需要機械設備，比如：開關、凸輪、閥門、船舶以及攪拌機等。

設計流程
設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。
