跑道关闭指示装置是机场地面主要的目视助航设备之一,承受当地典型风力载荷。本文应用流固耦合分析方法,在ANSYS Workbench有限元分析平台上,对指示装置在特定风场下进行仿真模拟,得到了指示装置所处流场的风速和风压分布。以流场计算结果为输入,对指示装置进行固体场的仿真分析,得到了结构的应力分布和变形情况。分析结果可为后期的结构改进和优化设计提供理论依据和参考。
The runway closure indicator is one of the major visual aids to the airport ground and withstands typical local wind loads. In this paper, on the platform of ANSYS Workbench finite element analysis, the fluid-solid coupling analysis method is used to simulate the indicating device in a specific wind field, and the wind speed and wind pressure distribution of the flow field are obtained. Taking the flow field calculation results as input, the simulation analysis of the solid field of the pointing device is performed, and the stress distribution and deformation of the structure are obtained. The results of the analysis can provide theoretical basis and references for the structural improvement and optimization design in the later period.
