摘要
系统地分析了在地震模拟振动台试验系统频率特性测试过程中，测量误差、环境对振动台驱动信号的干扰噪声及试验系统本身非线性等因素的影响，得出了对指导试验具有重要意义的结论，阐述了应用试验系统频率特性对试验进行数字补偿控制的方法，并列举一些实例．
Estimation of flequency charaCteristics is neccesary to a successful shaking tabletest. This paper analyzes the effect of measurement noise, environment disturbanceand nonlinearity of tested system on the frequency response estimation of theshaking table test system, provides important conclusions, and discribes digitalcompensation control technology.
