本文通过有限元静力分析及电测应力,对烟管锅炉新型管板结构-拱形管板进行了优化选型及强度研究,获得以下结果:(1)椭球形拱形管板优于扁球形拱形管板;(2)各种不同几何参数对管板应力的影响规律;(3)尽管螺纹管刚度下降,但对管板应力影响不大;(4)拱形管板管束区可以不加拉撑管。
In this paper, through the finite element static analysis and electrical test stress, the optimization type selection and strength of the new tube plate structure - arched tube plate of the tobacco pipe boiler were studied. The following results were obtained: (1) Spherical arched tube plate; (2) the influence of various geometric parameters on the stress of the tube plate; (3) the stress on the tube plate is not affected by the decrease of the stiffness of the threaded tube; (4) Do not brace up.
