摘要
为提高带式输送机托辊性能,同时降低输送能耗,文章通过仿真研究,提出首先在托辊辊筒内壁中心区域焊接圆环进行结构改进,并以此为基础,根据响应面参数优化设计辊筒厚度、圆环尺寸参数。经优化后,托辊总质量降为9.02 kg,降幅为23.1%,实现轻量化设计;最大应力上升为70.526 MPa,远小于托辊材料的许用应力值;最大变形值降为0.04735 mm,强度和变形值均满足要求。
In order to improve the performance of the belt conveyor idler roller and reduce the energy consumption in conveying,this paper proposes to improve the structure by welding a ring in the central area of the inner wall of the idler roller cylinder through simulation research.Based on this,the thickness of the idler roller cylinder and the size parameters of the ring are optimized according to the response surface parameters.After optimization,the total mass of the idler roller is reduced to 9.02 kg,with a decrease of 23.1%,realizing the lightweight design;the maximum stress rises to 70.526 MPa,which is far less than the permissible stress value of the idler roller material;the maximum deformation value is reduced to 0.04735 mm,and the strength and deformation value meet the requirements.
