摘要
建立了雷达天线座车车架有限元分析模型,并对雷达天线座车系统风压中心风速时程数值进行模拟,得到脉动风荷载时程样本。随后对车架进行模态分析和风载响应分析,得出车架在风荷载作用下的变形量和应力分布情况,为雷达天线座车在风荷载作用下车架的设计提供依据。
The FEA（finite element analysis） model of a radar antenna seat coach’s frame is established in this article.Then,the time-histories numerical value of the systematic wind pressure is simulated,and the time-histories sample of pulsating wind load is gained.Therewith,the modal analysis and the response analysis of the frame are carried through,and the deflection and stress distribution of the frame under wind load are drawn,which provides reference for the design of radar antenna seat coach＇s frame under wind load.
