结合某试验特点,编制MATLAB语言程序对振动台获得的原始数据进行处理。根据白噪声扫频结果获得模型结构的频率等动力特性,以及对地震波作用后的模型结构反应进行滤波和积分处理,获得模型结构的加速度和位移数据。通过对比滤波、积分处理后的位移和实测的位移,看出两者结果基本一致,说明数据处理方法正确,适用于其他振动台试验数据处理。
Combined with the characteristics of a test, the preparation of MATLAB language program to shale the original data processing. According to the results of white noise sweep, the dynamic characteristics of the model structure such as the frequency of the model structure are obtained, and the response of the model structure after the seismic wave is filtered and integrated to obtain the acceleration and displacement data of the model structure. Through comparative filtering, displacement after integral processing and measured displacement, we can see that the results of the two methods are basically the same, which shows that the data processing method is correct and suitable for other shaker test data processing.
