| Objective To check whether the structure of the vehicle antenna would be damaged under the wind load of force 9 wind. Methods With the vehicle antenna as the object of study, the Catia software was used to build a three-dimensional model of the antenna, and the ANSYS Workbench was used to perform the fluid-structure coupling analysis. The distribution of aer-odynamic load on the antenna under the interaction of the air flow field was obtained. The aerodynamic force was loaded to the coupling surface of the antenna by using the coupling surface node difference algorithm. A structural statics analysis was performed for the aerodynamic of antenna. Strain distribution and structural deformation of antenna under the influence of the air flow field were calculated. Results The lateral wind blowing pressure of the antenna was about 533.8 N, the swing was 186.02 mm; the forward wind blowing pressure was about 514N and the swing was 171.6 mm. Conclusion The structure of the vehicle antenna would not be damaged and the swing would not exceed 200 mm under the wind load of 20 m/s (force 9 wind). |
