摘　　要：为确定大直径滚筒斜切进刀时的最佳截割角度,使得滚筒破岩参数处于最佳值,采用EDEM进行滚筒煤岩截割模拟试验。以滚筒转速、牵引速度和进刀角度为试验影响因素,滚筒受载均值和截割比能耗为响应指标,采用二次响应面试验设计,建立响应指标与各影响因素之间的回归数学模型,并分析滚筒整体受载规律,利用响应面优化设计,得出滚筒最佳斜切进刀参数,为类似工程提供一定的理论指导。In order to determine the best cutting angle of large diameter drum during oblique cutting feed and make the drum rock breaking parameters at the best value,EDEM was used to conduct a simulation test of drum coal rock cutting.With drum speed,traction speed and feed angle as the influencing factors,the average load of drum and cutting specific energy consumption as the response indexes,a secondary response surface test design was adopted.The regression mathematical model between the response index and the influencing factors was established,and the whole load law of the drum was analyzed.The optimal miter feed parameters of the drum were obtained by the optimal design of the response surface,which provides certain theoretical guidance for similar projects.
