機械設(shè)計過程剖析---討論

天地一笑

機械設(shè)計過程：
（1）大腦中有一個大體的裝配草圖（機械結(jié)構(gòu)簡圖到機械結(jié)構(gòu)簡圖的設(shè)計）
& w7 @- T" a+ ]( L! i' \（2）裝配圖的設(shè)計
（3）零件圖的設(shè)計
$ _; p% t# G9 `' C7 h
這三個過程中第(1)步要繪制結(jié)構(gòu)簡圖就不那么容易，不知道如何可以繪制好機械結(jié)構(gòu)簡圖，是要學(xué)習(xí)《機械原理》？
（2）.(3)步需要很強的機械繪圖能力，我在這方面也很弱，感覺自己直接用二維軟件時繪圖時比較困難。用三維軟件先繪制成實體，然后在轉(zhuǎn)變成二維還稍微輕松點。

方圖

不知道有沒有人做過流程圖。 下面是我從美國Robert L. Norton 著的 "An Introduction to the Synthesis and Analysis of Mechanisms and Machines" 上摘錄的，個人覺得有點意思，供參考。

The Design Process
"...this is not a process in which one proceeds from step one through ten in a linear fashion. Rather it is, by its nature, an iterative process in which progress is made haltingly, two steps forward and one step back. It is inherently circular..."
