车载微波天线风力作用下结构强度分析

Structural Strength Analysis of a Vehicle Microwave Antenna under Wind Load

以弹塑性理论和有限元法为基础,运用ANSYS有限元分析软件对车载微波天线进行了不同风力载荷条件下的有限元建模与计算,得到并分析了该车载微波天线在风力作用下的应力分布部位及应力值。根据车载天线的主要技术指标,计算结果满足系统可靠性要求,这些为结构的进一步改进提供了理论依据。

On the basis of elastic-plastic theory and finite element method, the software ANSYS is employed to carry out a finite element modeling and analysis for the vehicle microwave antenna,which is subjected to the different wind load. The effective stress in the antenna＇s stress distribution is evaluated. According to the basic technical specification of a vehicle antenna, the result satisfied the reliability requirements of the system. Some useful conclusions are gained for the improvement of this structure.
