摘要
以DTL160/330/3 × 1 600型带式输送机为研究对象,在对输送机以及传动滚筒进行概述的基础上,利用UG和ANSYS软件建立了滚筒的有限元模型并分析其应力和变形情况.发现最大应力和变形分别为133.64 MPa和3.823 7mm,强度和刚度上均存在明显冗余问题.对支撑环、筒体和轮辐进行轻量化设计,去除了部分区域的体积,使得滚筒整体质量降低了 11.18％.对新的滚筒结构进行有限元分析,发现最大应力和变形均有所增加,但是安全系数最小为1.79,在煤矿机械标准要求范围内,可以满足实际使用要求.将新的滚筒结构应用到带式输送机中,经过实践应用,达到了预期效果,产生了良好的经济效益.
Abstract
Taking the DTL160/330/3 × 1 600 belt conveyor as the research object,based on the overview of the conveyor and the drive roller,the finite element model of the roller was established and its stress and deformation were analysed by using UG and ANSYS software.The maximum stress and deformation were found to be 133.64 MPa and 3.823 7 mm,respectively,with obvious redundancy problems in strength and stiffness.The lightweight design of the support ring,cylinder body and spokes removes the volume of some areas,resulting in an 11.18％reduction in the overall weight of the drum.Finite element analysis of the new drum structure reveals that the maximum stress and deformation have increased,but the minimum safety coefficient is 1.79,which is within the requirements of the coal mine machinery standard and can meet the requirements for practical use.The new roller structure is applied to the belt conveyor,and after practical application,it achieves the expected effect and produces good economic benefits.
