【摘要】 针对地震模拟振动台试验中数据处理量大、繁琐的现状,提出采用MATLAB编程的方法处理。通过对数据进行峰值调整、趋势项消除、滤波等预处理,采用频域微积分的方法进行加速度、速度和位移的转换,并通过编程实现结构动力特性的提取。经实际使用,上述方法高效、简便,数据处理精度高,可供振动台试验时使用。更多还原

【Abstract】 In order to solve the problem of large cumbersome data processing during shaking table test,a processing method was presented by using MATLAB.By data preprocessing,such as peak-value adjusting,trend term eliminating,wave filtering,etc.,frequency-domain calculus was used in the transformation of acceleration,velocity and displacement.And the dynamic characteristics of the structure were extracted by programming.The method with high accuracy of data processing was proved to be simple and efficient,thus it could be used in shaking table tests.更多还原
