摘要

摘要: 薄煤层采煤机装煤效率的问题一直备受关注，为了使采煤机在截割功率允许范围内，装煤率得到改善并保证能耗最小、切削面积最大、进而达到截割性能最优，对采煤机运动学参数匹配问题进行了研究。采用EDEM软件，建立了采煤机截割部的离散元仿真模型，分析了滚筒转速、牵引速度与实际装煤量、装煤率之间的关系；采用MATLAB软件，建立了滚筒截割比能耗以及切削面积的数学模型，以装煤率、实际装煤量、切削面积、截割比能耗为目标函数，建立了采煤机滚筒运动学参数的多目标优化方程，通过优化得到了牵引速度与滚筒转速的最佳匹配值。研究表明：当滚筒转速为53.4 r/min、牵引速度为8.9 m/min时，滚筒性能达到最优。此时滚筒装煤率为59.025 7%，实际装煤量200.541 1 t/h，切削面积56.667 cm2，截割比能耗0.874 kW·h/m3。

Abstract: In the thin coal seam, the shearer's loading rate is always a question that received much more concerns. In order to improve the loading rate and ensure the minimum energy consumption, the biggest cutting area, in the range of cutting power, and then achieve the optimal cutting performance, the shearer's kinematics parameter matching is studied. The discrete element simulation model of shearer's cutting unit is established by EDEM software, based on the relationship of drum rotating speed, haulage speed and loading rate, actual coal capacity. The cutting specific energy consumption and cutting area mathematical model is established by MATLAB software. Take the loading rate, actual coal capacity, cutting area and specific energy consumption as objective function, the multiobjective optimization equation of the kinematic parameters of shearer drum is established. The optimum matching value of the haulage speed and drum rotating speed is obtained by optimization. The research results show that when the drum rotating speed is 53.4 r/min and haulage speed is 8.9 m/min, drum performance achieves to the best; and then the loading rate is 59.025 7%, the actual coal capacity is 200.541 1 t/h, cutting area is 56.667 cm2, cutting specific energy consumption is 0.874 kW·h/m3.
