摘要:
以某固定管板换热器为例,对数值模拟方法和管束支撑进行了研究。通过建立不同单元类型的换热器有限元模型,以换热器壳体轴向应力为指标,对比换热器筒体和管子中的轴向应力及管板挠度,研究了不同换热器有限元分析方法的合理性,考察了管板横向变形和换热管外侧及筒体内侧施加的壳程压力对筒体轴向应力的影响,以及换热管对换热器管板的支撑作用。
Abstract:
This paper, taking a fixed tube-sheet interchanger as a case, analyzed the numerical simulation method and tube bundle support. Different unit types of finite element models for the heat interchanger were created, comparing the axial stress and tube sheet deflection in the shell and tube of the heat interchanger, with the axial stress as an index, the rationality of different finite element analyses on the heat interchanger was analyzed, and the influence of the lateral deformation of the tube sheet on the axial stress of the shell was examined, as well as the influence from the pressure both exerted by the outside of the heat exchange tube and the inside of the shell. The support of the heat exchange tube for the tube sheet of the heat interchanger was also analyzed.
