Mechanical and CFX parts of the finite element analysis software ANSYS were employed to study the mechanical properties of a wave-plate mist eliminator by the method of Fluid-Structure Interactions (FSI) numerical simulation, and related experiments were conducted to verify the reliability of the numerical simulation results. The results indicate that the maximum relative error between the simulation results and the experimental results is 11%, and the average relative error is 4%. Maximum stress of the FSI results was located in the constraint position, which is also the main failure position in engineering practice. In order to investigate the effects of four parameters, namely, bend number, spacing, bend angle, and inlet velocity, onσmax,σmax1 and wtotal this paper designed a L9 (34) orthogonal table by selecting the maximum stress in constraint placeσmax, the maximum stress in first bend placeσmax1, and the maximum deflection wtotal as controlling indexes. The results show that the effectiveness of the four parameters onσmax have the order of bend angle>inlet velocity>bend number>spacing, the order forσmax1 is:bend angle >bend number>inlet velocity>spacing, and inlet velocity > bend angle > spacing > bend number for w total . The orthogonal analysis indicates that the optimal parameters are bend angle 120 °, spacing 10 mm, bend number 1, inlet velocity 3 m⋅s-1.%工业应用较广的折流板除雾器在使用过程中经常出现坍塌、断裂等失效问题，造成设备分离效率下降，影响整个生产工艺流程。今采用有限元分析软件ANSYS中的Mechanical与CFX模块对折流板除雾器的力学性能进行了流固耦合数值模拟，并用实验对模拟结果进行了可靠性验证。结果表明，模拟和实验结果之间最大相对误差11%，平均相对误差4%。流固耦合结果中最大应力σmax出现在折流板约束处，是工程实际中主要失效位置。选取折流板除雾器约束处最大应力σmax ，进口第一块折板的最大应力σmax1和最大挠度wtotal为控制指标，设计L9(34)正交试验研究级数、间距、折角、进口气速对σmax、σmax1和wtotal的影响规律，结果表明对σmax的影响由强到弱依次为：折角>风速>级数>间距；对σmax1的影响由强到弱依次为：折角>级数>风速>间距；对wtotal的影响由强到弱依次为：风速>折角>间距>级数。根据正交分析确定最优的条件为：折角120°、间距10 mm、级数1级、风速3 m⋅s-1。
