【摘要】：針對(duì)超深礦井提升機(jī)多層纏繞,研究多層纏繞鋼絲繩圈間過(guò)渡時(shí)的加速度變化,運(yùn)用提升鋼絲繩的動(dòng)張力微分方程和MATLAB中的Simulink模塊,建立對(duì)稱(chēng)及非對(duì)稱(chēng)雙折線過(guò)渡繩槽下多層纏繞鋼絲繩的動(dòng)張力仿真模型并對(duì)仿真結(jié)果進(jìn)行分析比較。結(jié)果表明,多層纏繞鋼絲繩在圈間過(guò)渡時(shí)產(chǎn)生的加速度變化會(huì)對(duì)鋼絲繩的動(dòng)張力產(chǎn)生明顯的影響,采用對(duì)稱(chēng)式折線繩槽進(jìn)行圈間過(guò)渡時(shí)的動(dòng)張力大于非對(duì)稱(chēng)折線繩槽,在提升階段的后期此現(xiàn)象尤為明顯。這些結(jié)果對(duì)超深井提升系統(tǒng)多層纏繞研究有重要的參考價(jià)值。
[Abstract]:In view of multi-layer winding of super-deep mine hoist, the acceleration change of transition between multi-layer winding wire rope rings is studied. The differential equation of dynamic tension of hoisting wire rope and Simulink module in MATLAB are used. The dynamic tension simulation model of multi-layer winding wire rope under the grooves of symmetrical and asymmetric double broken wire transition rope is established and the simulation results are analyzed and compared. The results show that the dynamic tension of the wire rope is obviously affected by the acceleration change of the multi-layer winding wire rope during the transition between the rings. The dynamic tension of the symmetrical winding wire rope groove is larger than that of the asymmetric wire rope slot during the transition between the rings. This phenomenon is particularly evident in the later stages of ascension. These results have important reference value for the study of multi-layer winding in ultra-deep well hoisting system.
