| 摘 要： | 以模态分析的相关理论为依据,在ansys环境下建立了某机载雷达天线座理论模态分析模型。通过理论模态分析与试验模态分析两种方法获得了天线座模态信息,并对理论模态与试验模态相结合进行了分析。分析结果表明,基于ansys环境下建立的天线座理论模型是正确的,结合部建模是合理的,模态分析结果是准确的;试验模态分析方法是可行的,且没有遗漏低阶模态信息。此模态分析方法为其它类似结构提供了一定的参考价值;模态分析与试验结果对于天线座的动态性能研究、雷达结构总体设计以及天线座优化设计提供了强力的技术支持。

| Abstract: | According to theories correlative with mode analysis,a theoretic mode analysis model was set up on the base of ansys. Modal information of antenna pedestal was obtained by means of both theoretic mode analysis and experimental mode analysis. And the result of mode analysis was analyzed jointly. The result of analysis indicates that the theoretic mode analysis model built on the base of ansys is correct,the model of joint-part is reasonable,the result of mode analysis is exact,the method of experimental mode... |
