鋼絲繩滑程 的英文怎麼說
中文拼音 [gāngsīshénggǔchéng]
鋼絲繩滑程
英文
wire line slippage-
Through the wire rope fatigue test, for the first time this dissertation investigated the law of the axial mfl changes of wire rope. the results showed the axial magnetic permeability of the reciprocating and rectilinear part of wire rope gradually increases and its distribution tends evenness. but that of the glide wheel bending part gradually decreases and its distribution tends to unevenness
通過鋼絲繩的疲勞實驗，本文首次研究了鋼絲繩彎曲疲勞歷程中周向漏磁通的變化規律，發現鋼絲繩的直線往復段軸向磁導率逐漸增加，且分佈趨向均勻一致，而位於滑輪彎曲段鋼絲繩軸向磁導率逐漸減小，分佈趨向不均勻。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。
