predesign 中文意思是什麼
predesign
解釋
初步設計,草圖設計-
Firstly, the predesign is carried out by use of the conventional analysis, and then the acceleration curve of the cam driven component is processed and revised discretely according to the requirements of dynamics performance. the design equation based on a refined finite - difference algorithm is established and the calculating process is realized by the computer programs. consequently, the cam profile with good performance can be attained
該方法先用常規解析法作初步設計，根據動力性要求對從動件加速度曲線進行離散化處理和修正，再用有限差分法建立凸輪型線的設計方程式，通過計算機程序進行計算求解，因而可以獲得優良性能要求的凸輪型線。
