| 中文摘要: |
| 车载雷达在行军过程中，风载荷会对雷达的零部件结构刚、强度产生影响，尤其是其使用寿命。通过分析雷达拓扑结构，将雷达天线反射面柔性化处理，建立车载雷达天线刚柔耦合模型；根据军用标准，编制了3种路面谱，依据风洞试验得到的风载荷系数，施加稳态风载荷，进行行驶动力学仿真，获得雷达天线重要零部件的动态参数，得出了不同种路面下雷达系统所能承受的极限风载荷，为新型雷达零部件设计提供依据。 |

| Wind load has effect on some critical parts in structure rigid strength of vehicle radar system in running situation. A rigid-flexible coupling model of radar antenna was established, in which the antenna reflector surface was considered as flexible body, through analysis of topology structure. Three kinds of road spectrum were made according to military standards. The steady wind load obtained from wind tunnel test was applied to simulate the process of dynamic vehicle. The dynamic parameters of some important parts and the limited wind load which the radar system can endure in different types of road spectrum were acquired. The purpose was to provide reference for general design and part design of new type radar system. |
