通過採用反饋加前饋控制、非線性補償、狀態反饋和根據狀態對增益編排,獲得了對液壓正鏟挖掘機的高精度控制效果和高穩定性。In order to break through the traditional technology and the conception of equipment design, suggest to use bunchy phase deep hole or big diameter deep hole in laneway to realize the exploding of high step on opencast working ; digging with big contain forklift to realize the continuous transportation of dragline - mobile convolution crusher - belt transportation machine, therefore form a new technology system that be propitious to increase collectivity technique and economic benefit
為突破基於常規工藝和設備配套的設計理念,推薦採用束狀階段深孔或在巷道中採用大直徑深孔的方法實現露天開採的高臺階穿爆作業;採用大斗容索鏟下挖作業實現自工作面開始的索斗鏟移動式旋迴破碎機帶式輸送機的連續運輸工藝,從而形成有利於提高露天開采設計總體技術經濟效果的新的工藝技術系統。A small implement with a pointed, scoop - shaped blade used for digging, as in setting plants
手鏟刀身尖突並呈鏟狀的小型器具,在種植植物時用來挖土The excessive hardness of the wood, and having no other way, made me a long while upon this machine, for i work d it effectually by little and little into the form of a shovel or spade, the handle exactly shap d like ours in england, only that the broad part having no iron shod upon it at bottom, it would not last me so long, however it serv d well enough for the uses which i had occasion to put it to ; but never was a shovel, i believe, made after that fashion, or so long a making
我慢慢把木塊削成鏟子的形狀,鏟柄完全像英國鏟子一樣,只是鏟頭沒有包上鐵,所以沒有正式的鐵鏟那麼耐用。不過,必要時用一下也還能勉強對付。我想,世界上沒有一把鏟子是做成這個樣子的,也決不會化這么長的時間才做成一把鏟子。With regard the front shovel, the main research tasks are the structure design, the space shape design of the shovel surface, the research of the spring obstacles - avoiding mechanisms, the matching calculation and analysis of the whole truck ’ s capacities
本文的主要工作如下: ( 1 )研究分析清雪車的國內外現狀及發展趨勢,總結清雪車分類。 ( 2 )建立dqx清雪車前雪鏟三維模型作為分析改進的基礎。At the same time, the dissertation compiling the program to solve the mathematical model by visual basic, predigest consequently process of solving and grain more precise value, on the side, compare resistance state of the different parameter and simulate the curve of resistance to optimize sciencly structure and design parameter of subsoiler
同時,本文利用計算機高級語言vb編制求解數學模型的程序,從而進一步簡化了計算過程,並且使得到的結果更加精確,並可以比較各種不同參數情況下的受力狀態,模擬出受力曲線,以科學地優化深松鏟的結構和設計參數。And then validate the mathematical model by trough experimentation, prove that the model can show totally draughting resistance of subsoiler. at last, simulati ng process of work by programming in visual basic, observe distinctly situation of working and resistance and precisely control the process of work and design better performance of subsoiler
最後,利用了計算機語言vb編程,實現深松鏟工作過程的模擬,可以直觀的觀察深松鏟的工作狀況和受力情形,以更加精確的控制深松鏟的工作過程和設計出性能更加優越的深松鏟。And the field of scientific research have been attached importance to research of subsoiling and develop of subsoiler, and gained considerable development, but subsoiling technology has not been extensive application, subsoiler has so many limitations too, and great resistance is prominent limitation. this dissertiation start with improving the status of resistance, optimizing parameter of structure, ploting structure graph of subsoiler by autocad, and constituting mathematical model of subsoiler resistance, finding out every affect factor of resistance, it is not only significant to optimize subsoiler, but to gain more precise value and parameter. and that it can detract the process of producing sample, experimentation and correcting, in addition to economizing time, saving resource and enhancing efficiency
本文從改善深松鏟受力狀況、優化其結構參數以更好的滿足深松要求入手,利用計算機輔助設計( autocad )技術繪制深松鏟的結構圖形以利於其分析和設計,並通過對現存深松鏟的結構和受力分析,建立了深松鏟工作狀態的受力數學模型,找出了影響深松鏟受力的各個因素,不僅對深松鏟的優化有著重大的意義,而且可以得到更加精確的數值和參數,並減少了必須生產出樣機進行試驗、修正等煩瑣的過程,大大節省了時間,節約了資源,提高了生產效率。分享友人
