Structures and performances of data acquisition and processing systems in dynamics tests

  • 摘要: 文章在總線結(jié)構(gòu)、硬件組成、數(shù)據(jù)管理模式、掃描正弦數(shù)據(jù)處理方法（頻率辨識、幅值估計）方面研究了目前動力學(xué)環(huán)境試驗(yàn)各種數(shù)據(jù)采集系統(tǒng)的特點(diǎn)和差異，同時對未來超大型數(shù)據(jù)采集系統(tǒng)的發(fā)展趨勢進(jìn)行了分析。

     

    Abstract: This paper studies the characteristics and the differences of various data acquisition and processing systems in terms of bus structure, system architecture, data management and processing methods for sine sweep signals, frequency identification and response estimation. The development trend of larger data acquisition system is also discussed.
