摘要
基于相关性理论建模方法,对空间遥感器进行仿真模态和试验模态的相关性分析。并通过关键参数的灵敏度分析和优化,实现了对遥感器有限元模型的修正。验证了相关性理论应用在遥感器结构动力学模型修正方面的可行性。
The paper discusses the process of computer and test aided modeling technique based on correlation method. A certain kind of space remote sensor is used as an example to verify the capability for dynamic model updating. First the correlation analysis of the test modal and simulation modal is made. Then the sensitivity analysis and optmization for key parameters are introduced and finally the results after model updating based on experimental data are given. It is verified that the dynamic model updating of the remote sensor can be realized with the correlation technique.
