| 摘 要： | 基于计算流体力学和弹性力学理论,联合应用Fluent软件与ABAQUS软件对某型雷达受风载荷条件下的刚强度进行了流固耦合模拟分析。对比了理论方法与直接耦合方法下雷达应力云图分布的不同;提取了瞬态流场的风压脉动频率特征;采用正弦载荷形式分析了雷达结构响应,为雷达设计过程中的刚强度校核提供更精确可靠的分析方法。

| Abstract: | A fluid-solid coupling simulation process was carried out based on the computational fluid mechanics and elastic mechanics, focusing on the discussion of analysis method for the wind load computation.The business software Fluent and ABAQUS were used.With the analysis of the stress distribution, the differences of the theoretical model and direct simulation model of wind load were compared. The dominant frequency features of instantaneous integral wind force were derived and the structure response with sine wave load were computed, providing a more accurate analysis method for strength check in the process of radar antenna design. |
