基于斐波那契数列的螺旋滚筒端盘截齿排列理论方法
Theoretical method of picks arrangement on end plate of shearer spiral drum based on Fibonacci sequence
摘要
Abstract
This paper proposes a theoretical algorithm of the law and parameters behind the picks se-quential arrangement of non-uniform truncation distance and circumferential distance by utilizing the char-acteristic law of Fibonacci series to address the relatively complicated picks arrangement on the end plate and imperfect theoretical design,which affects the performance of the spiral drum in cutting coal and rock.The study involves defining a quantitative evaluation method of the truncation groove symmetry in-dex,the incremental rate of the picks density and the specific energy consumption,and simulating the three-direction loading spectrum of coal-rock cutting by using the finite element.The results show that based on Fibonacci series arrangement,cut spacing and circumferential spacing of the picks arrangement match equivalently,which forms a periodic reverse-sequence sequential truncation of coal rock,and com-pared with the conventional picks arrangement,the symmetry index of the truncation groove increases by 23%-40%,the increment rate of truncation density of adjacent truncated lines is1.6 evenly,and the cutting ratio energy consumption is reduced by 4%-8%.The mean value of axial load of the spiral drum of sequential arrangement of picks is significantly reduced,which is 29%of the conventional end-disk picks,and the mean and peak values of vertical and horizontal truncated loads of the two end-disk picks arrangements are same basically.关键词
