long lead screw-
The optimization design of portal crane luffing system is the result that optimization design apply in engineering design, but because the engineering problem is complicated, the traditional optimization design method is not very successful. in this paper, the optimization of the single boom system with compensating pulley and level - balancing weight is studied. in the math model, the wire rope length encircled in the pulley and reel is considered, that enhance the optimization precision and introduce genetic algorithms, combine engineering tightly, that settle the difficult in the traditional optimization successfully
門機變幅系統優化設計是將優化設計方法應用於工程設計中的產物，但由於設計工程問題的復雜性，採用傳統的優化設計方法優化的成功率及效果並不理想。本文以單臂架變幅機構導向滑輪補償系統和杠桿? ?活對重臂架自重平衡系統的獨立模型及綜合模型為研究對象，考慮了滑輪和捲筒處包繞的鋼絲繩長度變化，從而提高了優化模型的精度，同時引進一種新型優化演算法? ?遺傳演算法，緊密結合工程實際，較為圓滿的解決優化過程中存在的問題。In the field of the electric discharge industry manufacture, the conventional " rotation motor + threaded spindle " movement mode is the leading condition, that gets the indirect linear movement
在電火花加工領域中，長期以來都是藉助于傳統的「旋轉電動機+滾珠絲杠」的間接進給方式，獲得所需的直線運動形式。
