采用非线性有限元方法研究除尘器壳体承受板顶竖向均布荷载作用的墙板发挥受力蒙皮作用时的破坏形式和承载能力,分析墙板厚度、墙板宽度、加劲肋间距、立柱横向支撑间距、立柱截面尺寸等因素对墙板承载能力的影响.结果表明:立柱受载水平较低时,墙板发生受剪屈服破坏;立柱受载水平中等时,墙板同时发生受压和受剪屈服破坏;立柱受载水平较高时,墙板发生受压屈服破坏.在同等立柱受载水平情况时,墙板承载能力随着墙板厚度增加、墙板宽度减小、加劲肋间距减小或者立柱支撑间距减小而增大.立柱截面尺寸增大使得立柱刚度增大时,立柱稳定性提高,墙板承载力增大. The non-linear finite element method is used to study the failure form and bearing capacity of the dresser shell subjected to the vertical uniform load acting on the top of the duster shell. The wall thickness, wall width, stiffener spacing, The results show that the wallboard is damaged by shear and yield when the load level of the column is low, and the wallboard is under the same compression when the column load level is medium And shear yielding damage; column under high load level, the wall panels under pressure yield damage.When the same column load level, the wall panel bearing capacity increases with the wall thickness, wall width decreases, the stiffener Pitch decreases or pillar support spacing decreases and increases.Pillar cross-section size increases so that the column stiffness increases, the column stability, wallboard bearing capacity increases.
