Abstract In order to solve problems of low design level, long development cycle, poor cutting performance of pick arrangement on drum shearer, the way of pick arrangement and the method of parameters determination were analyzed. A parametric design system of pick arrangement on drum shearer was developed by means of MATLAB GUIDE language. Variety of pick arrangement schemes could be designed after inputting design parameters of a drum and the rationality of schemes could be judged by using cutting order pattern, cutting pattern and drum load diagram. A simulation analysis of two kinds of pick arrangements of a usual 3starts vane drums was conducted as a practical example. The result showed that pick arrangement of aberrance 1 was superior to aberrance 2 in cutting performances. The research indicates that the system can improve the quality of drum design, the design schemes is intuitive, the design result can be analysed qualitatively and quantitatively, which lays the foundation for the design of drum with good quality and performance.

滚筒式采煤机截齿排列参数化设计系统的研究
为解决采煤机滚筒截齿排列设计水平低、研发周期长、截割性能差等问题，给出了截齿排列方式及其参数确定方法．利用MATLAB GUIDE语言编程，开发了采煤机滚筒截齿排列参数化设计系统．该系统通过输入设计参数便可设计出滚筒的多种截齿排列方案，利用截割顺序图、切屑图以及滚筒载荷图可判断设计方案的合理性．通过实例，对常用三头螺旋滚筒的2种截齿排列方式进行模拟分析，结果显示：畸变1式截割性能优于畸变2式．研究表明，该系统可提高滚筒设计质量，设计方案直观，设计结果可定性、定量分析，为设计质量好、性能佳的采煤机滚筒奠定了基础．
