緊繩法
英文
pulley method-
The carriage creaked and rattled as it flew over the rough stones, and the slightest obstacle under the wheels would have caused disaster ; but it kept on in the middle of the road, and those who saw it pass uttered cries of terror. ali suddenly cast aside his chibouque, drew the lasso from his pocket, threw it so skilfully as to catch the forelegs of the near horse in its triple fold, and suffered himself to be dragged on for a few steps by the violence of the shock, then the animal fell over on the pole, which snapped, and therefore prevented the other horse from pursuing its way
陡然地，阿里放下了他的長筒煙，從口袋裡抽出了繩索，巧妙地一拋，那繩圈就套在了離他較近的那匹馬的前蹄，然後忍痛讓自己被馬向前拖了幾步，在這幾步的時間里，那條巧妙地投出去的繩索已逐漸收緊，終于把那匹狂怒的馬的兩腳完全拴住了，使它跌倒在地上，這匹馬跌到了車轅上，折斷了車轅，使另外那匹馬也無法再向前跑了。Leremia could not deny, and his fingers played nervously with the fastening of the basket on his knees.
耶利米亞無法否認，他緊張地用手指擺弄著擱正膝頭綁草籃的繩子。To meet this challenge, a research project was supported by ministry of communication and bv shanghai zhenhua port machinery co. ltd. focusing on analysis of tdtcd ( traditional design theories of crane drums ) the paper has studied the impacts of features under the binding force of wire ropes, the end - plate and rope slot. this study is based not only on the thin shell theory and viscoelastic mechanics to calculate the strength and stability of drum, but also on an experiment with technology in " state of act "
本文結合交通部重點科技項目「港口起重機鋼絲繩傳動件高性能技術研究」和上海振華港機股份有限公司委託項目「起重機焊接捲筒極限壁厚研究」 ，針對起重機捲筒傳統設計方法偏於保守的情況，以薄殼理論和近代力學為基礎，以現代試驗技術為研究手段，對鋼絲繩緊箍力作用下的外載特性、端板、繩槽等因素對捲筒強度和穩定性的影響進行了系統的理論研究，在深入開展捲筒強度、穩定性和實驗模態分析等試驗的基礎上，提出了有別于傳統方法的捲筒強度、穩定性計算方法。Abstract : taking single - rope drum wind as analysing object, the paper analyses safety coefficient of main rope using the dynamic state method under speed up, constant the speed, reduce the speed and emergency braking, change law is gotten comparing them with " mine safety standards ", points out existing problems and solving methods of safety coefficient in selecting and using rope in home
文摘:以立井單繩纏繞式提升機為研究對象，從動態方面分析提升鋼絲繩安全系數，得出其在加速、等速、減速、緊急制動狀態下的變化規律，與我國《煤礦安全規程》的要求進行比較，指出目前國內選擇和使用提升鋼絲繩在安全系數方面存在的問題和解決辦法。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。Furthermore, a tight - line algorithm is presented, to give a shortest path from start point to the exploration site by processing the path - planning result of aco
在蟻群演算法規劃的基礎上提出一種緊繩演算法，對蟻群演算法的最後結果進行處理，最終給出了最優規劃路徑。In the light of the time co - reliance of the wire ropes, the calculation formula of the rope tension efficient was deduced through the law of conservation of energy before and after the wire ropes ware rolled. moreover, the feature problems of the load outside the drums under the binding function of the wire ropes were solved and the calculation method concerning the rope circle tension was derived
在考慮鋼絲繩時間相依特性的前提下，利用鋼絲繩卷繞前後的能量守衡關系推導了繩圈張力系數計算表達式，解決了鋼絲繩緊箍作用下捲筒外載荷的特性問題及其繩圈張力相關的計算方法。分享友人
