摘要
基于有限元软件ANSYS,建立了包括中箱体、花板、下立柱、横梁和灰斗等在内的某大型袋式除尘器结构的三维有限元模型,对除尘器结构强度进行了热力场仿真计算,给出了中箱体和灰斗的应力、应变等云图。具体分析了板结构分别采用压型钢板和平板加筋的中箱体变形规律及控制变形能力,提出了中箱体箱板的结构优化途径,为大型袋式除尘器工程设计和箱板优化提供了快速、经济的研究手段。
The finite element model of large scale bag filter, including middle housing, tube sheet, lower colunto, beam and ash bucket, is constructed based on software ANSYS. With the model, the structural strength is simulated and the stress and the strain contours of middle housing and ash bucket are. obtained. This paper analyzes deformation role of tbe middle housing employing profiles and plates respectively, and bring forward optimization structure of middle housing.
