| 摘 要： | 为了研究高耸烟囱筒壁开设烟道后对烟囱特性的影响,利用大型通用有限元计算软件ANSYS分别对120m、180m和240m 3种高度的烟囱进行数值模拟分析,分析内容包括考虑和不考虑烟道2种情况下的重力、风荷载及地震作用下的应力、应变。通过计算分析得到了考虑烟道时对烟囱的影响：烟道周围应力变化复杂,考虑烟道后结构的最大应力、应变的位置发生变化。

| Abstract: | In order to study if the flue on tube wall of high chimney will affect the characteristics of the chimney,this paper used the generally accepted finite element software ANSYSY to make a numerical simulation analysis to the chimney model of different height,including 120m,180m,240m.Its materials included the chimneys with and without the flue in order to get the stress and strain of chimneys,which under the effect of gravity,wind load or earthquakes.The impact to chimney owing to considering the flue will be... |
