摘要文章針對重型板式給礦機速度控制困難,提出了用變頻器控制電機轉速來控制變量泵液壓油流量,以實現對液壓馬達速度的調節方法。Abstract : in this paper, the feature of time - bifurcation for plate - beam stability is studied by mechanics model of plate - beam structure of rock in compression. the instability time of plate - beam is dependent on the rock material feature. delay bulking occurs under some load. the formula of time - bifurcation is given. the mechanisms of roadway floor heave and delay rockburst are preliminarity discussed
文摘:採用巖石板裂梁的縱向受壓的力學模型,考慮深部巖石的流變性,分析了板梁穩定性的時間分叉特性.板梁失穩與巖體的流變性質密切相關,在一定載荷下,經歷一段時間后會發生延遲失穩,給出了時間分叉點的計算式.並對深部礦井延遲性巖爆發生機制進行了初步分析
