中文摘要:
      目的 检验车载天线在九级风作用下结构是否会发生破坏。方法 以车载天线作为研究对象,应用Catia软件建立天线结构的三维模型,利用ANSYS Workbench对天线结构进行流固耦合分析,得到天线在空气流场作用下的气动载荷分布情况。通过耦合面节点差值算法将气动力加载到天线耦合面,对承受气动力的天线进行结构静力学分析,计算天线结构在空气流场作用下的应力分布情况和变形结果。结果 车载天线受到侧向风吹压力约为533.8 N,摆幅为186.02 mm;正向风吹压力约为514 N,摆幅为171.6 mm。结论 车载天线在20 m/s(九级风)的风载荷作用下,结构不发生破坏,且摆幅不超过200 mm。
英文摘要:
      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).
