機(jī)械設(shè)計過程剖析---討論

天地一笑

機(jī)械設(shè)計過程：
（1）大腦中有一個大體的裝配草圖（機(jī)械結(jié)構(gòu)簡圖到機(jī)械結(jié)構(gòu)簡圖的設(shè)計）
/ C- @/ j* E  ]2 c（2）裝配圖的設(shè)計
（3）零件圖的設(shè)計

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(jī)械結(jié)構(gòu)簡圖，是要學(xué)習(xí)《機(jī)械原理》？
) J2 I$ i9 C8 n; i5 v（2）.(3)步需要很強(qiáng)的機(jī)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。
期望大家給我點意見，謝謝了！

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

手繪也好，草圖也好，CAD也好只是設(shè)計中的一小部分，前期的方案設(shè)計和分析非常重要
