摘　　要：本文根据《塔式容器》NB/T47041-2014对自立式钢烟囱进行设计计算,再运用有限元程序ANSYS对设计计算结果进行验证。在设计过程中,应采取相应措施来减小烟囱振幅和避免烟囱产生共振。In this paper,the calculation for self-supporting steelstack design is carried out based on"Tower Vessel"NB/T47041-2014,and then the design calculation results are verified by using the finite element program ANSYS.In the design process,corresponding measures should be taken to reduce the stack amplitude and avoid resonance of the stack.

关 键 词：钢烟囱 有限元 共振 破风圈
