摘要

对煤斗筒体进行了有限元法结构应力计算

分析了不同状况下筒体的应力与变形。结合煤斗筒体的稳定性分析

判断煤斗筒体损伤属非轴向对称的局部屈曲失稳

而屈曲失稳的主要原因是筒体支撑安装有误和筒体的抗弯刚度裕度较小所致

Abstract

The finite-element structure stress computation of coal-bunker’s barrel shell has been carried out

and stress and deformation of the said barrel shell under different conditions are analyzed. Combined with the stability analysis of coal-bunker’s barrel shell

it is considered that the said barrel shell’s damage belongs to partial flexure unstability of non-axial symmetry

and the main cause of flexure unstability is as folliws; （1）there was mistake in suppotting and erecting the barrel shell; （2）the margin of barrel shell’s bending-resistance stiffness was smaller.
