机械设计过程剖析---讨论

天地一笑

机械设计过程：
# R7 h$ n$ w1 O8 l, G# j$ t! X（1）大脑中有一个大体的装配草图（机械结构简图到机械结构简图的设计）
+ G0 A+ E) p3 K（2）装配图的设计
（3）零件图的设计
* t7 ~5 `; ?: U
这三个过程中第(1)步要绘制结构简图就不那么容易，不知道如何可以绘制好机械结构简图，是要学习《机械原理》？
1 f" Z3 B( x4 c' N( G（2）.(3)步需要很强的机械绘图能力，我在这方面也很弱，感觉自己直接用二维软件时绘图时比较困难。用三维软件先绘制成实体，然后在转变成二维还稍微轻松点。

不知道有没有人做过流程图。 下面是我从美国Robert L. Norton 著的 "An Introduction to the Synthesis and Analysis of Mechanisms and Machines" 上摘录的，个人觉得有点意思，供参考。

8. detailed design:   this step usually includes the creation of a complete set of assembly and detail drawings or CAD part files, for each and every part used in the design.
9. prototyping and testing;
10. production

手绘也好，草图也好，CAD也好只是设计中的一小部分，前期的方案设计和分析非常重要
