摘要
针对某星载降水雷达结构动力学优化设计要求,在有限元分析的基础上,采用Kriging(克里金)代理模型对某星载降水雷达的有限元模型进行近似化处理,并利用改进遗传算法对其蜂窝板结构参数进行优化设计,获得较优设计方案.最终通过某星载降水雷达结构动力学优化设计案例以及力学试验证明该方法的有效性.
Abstract
In response to the structural dynamics optimization design requirements of a certain satellite-borne precipitation ra-dar,based on finite element analysis,the Kriging surrogate model is used to approximate the finite element model of the satellite-borne precipitation radar.The improved genetic algorithm is then employed to optimize the honeycomb panel structure parameters,resulting in a better design solution.Finally,the effectiveness of this method is demonstrated through a case study of the structural dynamics optimization design of a certain satellite-borne precipitation radar and mechanical experiments.
