机械设计

一台完整机器的设计是一个 复杂的过程。机械设计是一项创造性的工作。

设计工程师不仅在工作上要有创造性，还必 须在机械制图、运动学、工程材料、

材料力学和机械制造工艺学等方面具有深厚的基础知 识。

Machine Design

The complete design of a machine is a complex process. The machine

design is a creative work. Project engineer not only must have the

creativity in the work, but also must in aspect and so on mechanical

drawing, kinematics, engineerig material, materials mechanics and

machine manufacture technology has the deep elementary knowledge.

任何产品在设计时第一步就 是选择产品每个部分的构成材料。

许多的材料被

今天的设计师所 使用。对产品的功能，它的外观、材料的成本、制造的成本作

出必要的选择是十分重要的 。对材料的特性必须事先作出仔细的评估。

One of the first steps in the design of any product is to select the

material from which each part is to be made. Numerous materials are

available

to

today's

designers.

The

function

of

the

product,

its

appearance, the cost of the material, and the cost of fabrication are

important in making

a selection. A careful evaluation of

the properties

of a. material must be made prior to any calculations.

仔细精确的计算是必要的， 以确保设计的有效性。在任何失败的情况下，最

好知道在最初设计中有有缺陷的部件。计 算（图纸尺寸）检查是非常重要的。

一个小数点的位置放错，就可以导致一个本可以完成 的项目失败。设计工作的

各个方面都应该检查和复查。

Careful

are

the

of

a

design.

In case of any part failures, it is desirable to know what was done in

originally

The

is

of

importance.

The

project. All aspects of design work should be checked and rechecked.

计算机是一种 工具，

它能够帮助机械设计师减轻繁琐的计算，

并对现有数据< /p>

提供进一步的分析。

互动系统基于计算机的能力，

已经使计算机辅助设计

（

CAD

）

和计算机辅助制造（

CAM

）成为 了可能。心理学家经常谈论如何使人们适应他们

所操作的机器。设计人员的基本职责是努 力使机器来适应人们。这并不是一项

容易的工作，因为实际上并不存在着一个对所有人来 说都是最优的操作范围和

操作过程。另一个重要问题，设计工 程师必须能够同其他有关人员进行交流和

磋商。在开始阶段，设计人员必须就初步设计同 管理人员进行交流和磋商，并

得到批准。这一般是通过口头讨论，草图和文字材料进行的 。

The computer is a tool helpful to mechanical designers to lighten

tedious calculations, and provide extended analysis of available data.

Interactive

This certainly is not an easy work, because certainly does not have to

如前所诉，机械设计的目的是生产能够满足人类需求的 产品。发明、发现

和科技知识本身并不一定能给人类带来好处，只有当它们被应用在产品 上才能

产生效益。因而，应该认识到在一个特定的产品进行设计之前，必须先确定人

们是否需要这种产品。

If front sues, the machine design goal is the production can meet

the human need the product. The invention, the discovery and technical

knowledge itself certainly not necessarily can bring the advantage to

the humanity, only has when they are applied can produce on the product

the benefit. Thus, should realize to carries on before the design in a

specific product, must first determine whether the people do need this

kind of product.

应当把机械设计看成是机 械设计人员运用创造性的才能进行产品设计、系

统分析和制定产品的制造工艺学的一个良 机。掌握工程基础知识要比熟记一些

数据和公式更为重要。仅仅使用数据和公式是不足以 在一个好的设计中做出所

需的全部决定的。另一方面，应该认真精确的进行所有运算。例 如，即使将一

个小数点的位置放错，也会使正确的设计变成错误的。

Must regard as the machine design is the machine design personnel

一个好的设计人 员应该勇于提出新的想法，而且愿意承担一定的风险，当

新的方法不适用时，
