机械设计简介------（外文翻译）.doc

Mechanical design is the application of science and technology to devise new or improved products for the purpose of satisfying human needs. It is a vast field of engineering technology which not only concerns itself with the original conception of the product in terms of its size, shape and construction details, but also considers the various factors involved in the manufacture, marketing and use of the product.
People who perform the various functions of mechanical design are typically called designers, or design engineers. Mechanical design is basically a creative activity. However, in addition to being innovative, a design engineer must also have a solid background in the areas of mechanical drawing, kinematics, dynamics, materials engineering, strength of materials and manufacturing processes.


机械设计简介
机械设计是为了满足人类需要而制定出的新产品或者改进旧产品时对科学与技术的应用。 它是工程技术的一个巨大领域,这个领域不仅关注原先这种产品的尺寸，形状以及构造方式， 而且考虑涉及这种产品的制造，销售和使用的其它各方面的因素。
进行机械设计的各种各功能的人们被通常叫为设计者或者设计工程师。 机械设计基本上是一次创造活动。 然而， 除富有创新精神之外， 一位设计工程师也必须在机械制图，运动学，力学，材料工程，材料强度和制造工艺有一定的背景知识。
精确的说，机械设计的目的就是为了满足人们的需求。 发明，创造和科学知识它们自己可能不能让人获益； 但是只要他们合并在一起并设计产品，其益处就会被得到。因此，在一种特别的产品被设计之前，人的需求必须被鉴定，这一点应该被认识到。
