【摘要】 采用有限元方法 ,对雷达天线结构的应力、变形进行了计算分析。充分考虑天线安装、使用中的实际情况 ,兼顾杆件受力、变形情况和总体尺寸、重量等因素 ,既要保证结构的合理性又要保证天线承受的应力、应变最小 ,建立了有限元模型并进行了计算 ,为雷达天线的改进设计提供了依据更多还原

【Abstract】 The stress and distortion of a radar antenna structure are calculated analytically by using finite element method(FEM) Attention is paid to the factors of force applied on the antenna components,distortion,overall size and weight, rationality of the structure and the minimum stress and strain applied on the antenna are guaranteed A finite element model is built and a calculation is made,which provides basis for improving the design of radar antenna更多还原
