本文分析了振动台可动系统自振频率对结构模型动力试验的影响,介绍了用试验模态分析方法识别振动台的模态参数和共振试验、结构地震反应试验时振动台的响应特性。并对振动台的动力特性进行了综合分析和评述。
This paper analyzes the influence of the natural vibration frequency of the vibrating table movable system on the dynamic test of the structural model. The modal parameters of the vibration table and the response characteristics of the vibratory table during the resonance test and the structural earthquake response test are identified by the experimental modal analysis method. The comprehensive analysis and review of the dynamic characteristics of the shaking table.
