摘要

概述了国内外动力学模型修正技术的研究状况,研究了近些年发展起来的基于频响函数的动力学模型修正方法;利用航天器振动试验测量所得的频响函数,从理论上介绍了频响函数残差法、设计参数型频响函数法和摄动型频响函数法三种基于频响函数的动力学模型修正方法,为动力学模型修正技术的发展提供参考。

Abstract

This paper summarized the development of dynamic model improvement methods, and researched the refinement methods based on frequency and response functions, which had been developed in recent years. In order to make the full use of the frequency and response functions obtained in the vibration test, the paper introduced three dynamic model improvement methods with frequency and response functions such as residual method, design parameter method, method of perturbation and so on. The paper may supply useful reference to the development of the spacecraft model’s updating technology.
