以一种外壁带螺旋形导流板的钢烟囱为研究对象，运用 ANSYS Workbench 和 CFX 流体力学，对其结构进行了风载荷作用下的稳定性及静力分析，并根据规范要求，对各个工况载荷作用下的 Von mises 应力进行了强度校核。通过与相同工况下的传统钢烟囱对比可知，该种改进型钢烟囱的结构更加安全稳定，为设计大高径比和高抗弯强度的钢烟囱提供了新的设计依据。

Took a chimney outer wall with a spiral guide plate in the paper.Research the chimney structure of stability and static force analysis under wind loads by using ANSYS Workbench and CFX fluid mechanics.According to the specifica-tion requirement for various loads,the strength under the Von Mises stress by checking.To comparison with ordinary chimney in the same condition,the improved chimney has more security and stability structure.Provide a new kind of design basis to design the chimney with large height to diameter ratio and high bending strength.
