Lesson 20:Engineering Problem-Solving Methodology

第二十课：工程师解决问题的方法论（
1-6
段）

许多年来，在很多工业和科技领域，
工程师们已经赢得了作为注重细节，
善于寻出正确答案
的 的思维清晰的思考者应得的声望。
他们不仅获得了尊重，
并且大众对他们设计并制造的产
品也给与了足够的信任与信心。

工程师们希望彼此之间提出的计算结果，
测试结果 ，
技术工作能够清楚简洁，
令人信服，
有凭有据。
机械工程中每个数量都由两 部分组成：
数值和单位，
失去其中一个那么另一个也
将变得毫无意义。并且在职工程师 在密切注意数字的同时也同样密切注意单位是否正确。

除了单位的问题，
工程师们还 必须获得问题的数据结果，
如材料的强度是多少？质量是
多少？在什么温度？等等。
他 们通常面对着一些不确定和未完善的一些信息。
在一项设计的
开始阶段，
例如，最终产 品的形状和尺寸并不确定，如果是这样的话，
就没有必要在第一步
去设计它们，仅仅粗略的估计 一下就可以了。
然而，工程师仍然有工作要做，并且这些形状
与尺寸必须从某处开始设计。
因此，
工程师们用近似法给那些仍然不知道的数值赋值，
虽然那些近似法并不完 美，
但
是肯定比随意猜测和什么都不做要好。机械工程师们用他们的常识、经验、直觉、判断力 、
和物理定律通过一种叫数量级近似法的方法去寻找答案，
而且机械工程师很乐意做出合理的< br>近似。

在你的机械工程的课程学习中，
你应该培养处理问题的能力去符合其他 工程师们对你的
期望的标准。
正确的处理问题的方法论对你获得正确的答案非常重要，
而且你传递给别人的
结果能让人信服。为了处理问题，以下的一些指导将会对你非常有帮

MODERN MACHINE DESIGN TECHNOLOGIES







Abstract:
Mechanical

in
engineering
design
plays
an
important
role.
Looking
modern mechanical design technology development prospects, and we care about is
undoubtedly an important research subject, but only on this basis, we can plan for the
mechanical

proposals.
According

However, product design, especially the means of mechanical product design program,
it appears to be inadequate,whichcan not

keep up with needs of the times. At present,
computer-aided
