基于代理模型的批产化卫星动力学试验舱内响应预示方法
A method for internal response prediction based on surrogated model for batch production satellites in dynamics test cabin
摘要
Abstract
In this paper,an internal response prediction method based on surrogate model was proposed for spacecraft structural dynamics test cabin.The feedforward neural network(FNN)and the Kriging model were applied respectively so as to predict the internal measurement point response using actual external measurement data obtained in the sinusoidal sweep frequency test.The prediction results by the two methods were compared through the examples of a component-level product and a system-level spacecraft.The effectiveness of the surrogate prediction method and the influence of sample number on the prediction accuracy were discussed and analyzed.This study may provide a reference for measurement point tailoring in the following dynamics test for batch production spacecrafts.关键词
