| 摘 要： | 以环境随机激励作用下的大型塔架结构为研究背景,提出了基于Polymax算法的大型复杂系统模态参数识别方法。首先针对大型塔架设计环境激励响应信号测试系统,然后对获取的激励响应信号进行分析和截取,选出各组试验中理想的响应信号段,最后基于Polymax算法对截取信号段进行参数识别,并将获取的结果进行模态验证。结果表明：该方法对于大型塔架模态参数的识别具有较高的精度。

| Abstract: | Based on the background of a high tower structure under environment random excitation,large-scale complex system parameter identification based on Polymax method is presented in this paper.Firstly,the system of testing environment excitation response signal for large tower is designed.Secondly,the obtained signal is analysed and intercepted,and then the ideal signals are selectted from each experiment.Lastly,the intercepted signal is identified for parameters based on Polymax method.The obtained result show... |
