摘要
针对雷达产品特点,对雷达两个比较重要的分系统,即天线座分系统及天线分系统的结构设计进行了分析,总结了建立这两个分系统有限元模型进行模态分析的思路及常用的简化方法,并针对某一雷达产品所采用的立轴式天线座及双反射体天线进行了模态分析。
Based on understanding of radar products of our institute, this paper analyses structural design of two important subsystems of radar system, namely the antenna pedestal and antenna. The concept and simplified method of establishing FEM of these two nalysis for an elevation antenna pedestal subsystems to complete model analysis are summarized, and model awith a standing azimuth axis and an antenna with main reflector and sub-reflector by ANSYS software is carried out.
