摘要
利用计算机和数据采集卡,采用LabVIEW编程,构成虚拟仪器。对缓冲材料振动传递率试验中的激励、响应加速度,经数据采集、滤波、数据压缩以及统计处理,将两路加速度信号在相同频率下整周期的均方根值对应相比,得出传递率。该软件具有良好的用户界面、便利的图形显示功能。
A virtual instrument constituted with a PC and a data acquisition card as its hardware platform, and with LabVIEW as its programming language. Power acceleration and response acceleration can be collected by the vibration transmissibility test to packaging material. Through date acquiring, filtering, compressing, and statistically processing, and comparing the two of the full cycle root-mean-square under the same frequency, ultimately the vibration transmissibility can be obtained. This software has a favorable user interface to facilitate the graphical display.
