由于管板上开有众多的不连续通孔,因而其应力分布、强度问题十分复杂,为了弄清管板的受力状态,给废热锅炉管板的强度设计提供参考资料,在没有相应规范的情况下,本文对此新型废热锅炉的管板建立了试验模型,并进行了应力测定,实测结果和有限元计算值基本上接近。 Because there are numerous discontinuous holes in the tube plate, the stress distribution and the strength of the tube plate are very complicated. In order to find out the stress state of the tube plate and provide the reference for the strength design of the tube plate of the waste heat boiler, In this paper, a test model was established for the tube plate of the new waste heat boiler, and the stress was measured. The measured results and the calculated values ​​of the finite element are basically close to each other.
