机载天线罩透波窗结构参数优化分析

摘要

在考虑机载气动载荷影响的情况下，运用ANSYS 软件对某机载天线罩透波窗开口形状和复合材料铺层顺序等结构参数变化分别进行力学仿真分析，依据仿真结果确定了该天线罩透波窗结构的优化参数，比较明显地降低了该天线罩透波窗结构在气动压力作用下的正应力和剪切应力水平。%Considering the influences of Airborne aerodynamic loads, the structural parameters of airborne radome, such as electromagnetic window shape and stacking sequence, are simulated and ana-lyzed by ANSYS.Based on the results, the optimize parameters are determined for radome structure de-sign, and the normal stress and shearing stress on the joint corner of the radome are decreased obviously.
