MATLAB在地震模拟振动台试验中的应用
THE APPLICATION OF MATLAB IN SHAKING TABLE TEST OF SEISMIC SIMULATION
【摘要】 针对模型结构振动台试验在前期、后期中均需要处理大量数据等特点,采用MATLAB语言及其强大的工具箱函数进行编程。试验前期,受困于振动台作动器量程的限值,需要编制程序对原始地震波数据进行频谱分析、滤波等处理。试验后期,根据白噪声扫描结果获得模型结构的自振频率等动力特性,以及试验采集到的模型结构加速度响应等数据,均需要进行滤波和积分处理。经实际使用,利用MATLAB语言进行编程,具有简捷、精度高等特点,可以推广到其他试验数据处理中去。
【Abstract】 In combination with the characteristics of shaking table test of model structure in the early or late,large amounts of data are needed to be solved. This article designed some programs by means of MATLAB language and its powerful toolbox functions. Trapped in the limit value of the shaking table actuator before the test,some programs are needed to process the spectra analysis,the filtering of the original seismic wave data. According to the results of the scan of the white noise,the dynamic characteristics of the natural frequency of model structure were obtained,as well as the acceleration response of the model collected during the test. All of the data collected in the test were needed filtering and integration processing. Using MATLAB programming language is proved to be simple and high precision,which can be generalized to other test data processing.
