基于环境激励的塔器模态参数识别研究
Research of the Modal Parameters Identification Method for the Tower under Ambient Excitation
摘要
Abstract
The modal parameters of the tower are the main parameters of the dynamic characteristics.How to obtain the modal parameters is an urgent problem.This paper is the first to identify the modal parame-ters of the tower by ambient excitation method.Combining with the random decrement technique,modal parameters are extracted from the acceleration response signal.Numerical simulation and practical testing show that the method proposed in this paper has the feature of high precision and easy completing.This method can give a reference to future research.关键词
