针对采煤机滚筒受力的问题,采用最大似然函数和改进的牛顿-拉夫森算法,对上湾矿采煤机的载荷谱进行分析处理,求出采煤机的截割载荷及其服从的伽玛分布的概率密度函数,进而得到牵引速度对截割载荷的影响。
Aiming at the problem of shearer’s bearing force, the maximum likelihood function and improved Newton-Raphson algorithm are used to analyze and process the load spectrum of Shearer Mine Shearer. The cutting load of shearer and its compliance The probability density function of the gamma distribution, and then get the traction speed on the cutting load.
