Abstract: In order to improve the working performances and design efficiency of shearer drums，and considering the size constraint relation and performance index of shearer drums，this paper presented a the optimization model of the shearer drums where the loading efficiency， cutting energy consumption and load fluctuation were taken as the optimization goal，and the leaf thickness， leaf helix angle， number of teeth， number of teeth on the same line and teeth-installing angle as the optimization variables. Herein， NSGA-Ⅲ algorithm was used to optimize the model of the constrained multiple objective shearer drums. The optimization design system of shearer drums was developed by MATLAB. Taking the parameters of coal and  working conditions in the cutting experiments of some companies as the inputs， the optimum design scheme of the rollers was obtained through the optimization design system of the shearer drums.The optimization results show that the capacity of coal loading is increased by 12.7%， the energy consumption of cutting ratio is reduced by 8.0%， and the load fluctuation is reduced by 20%， compared with MG500/1130WD shearer drums. The shearer drum optimization design system combines CAD technology and IGES to form a complete 3D virtual model of shearer drums.

摘要： 为了提高采煤机滚筒的工作性能和设计效率，综合考虑采煤机滚筒尺寸约束关系及性能指标，提出了以装煤效率、截割比能耗和载荷波动为优化目标，叶片厚度、叶片螺旋升角、叶片头数、同一截线上的齿数和截齿安装角为优化变量的采煤机滚筒优化模型。采用NSGA-Ⅲ算法对提出的有约束多目标采煤机滚筒优化模型进行寻优，利用MATLAB开发了采煤机滚筒优化设计系统，以某公司截割实验的煤岩参数、工况条件为输入，通过采煤机滚筒优化设计系统得到滚筒最佳设计方案，该滚筒相对于MG500/1130WD采煤机滚筒，装煤能力提高了12.7%、截割比能耗降低了8.0%、载荷波动系数减小了20%。结合CAD技术以及初始图形交换规范（IGES）形成了完整的采煤机滚筒三维虚拟模型。
