摘要
介绍了自制的用于热声驱动脉管制冷装置的计算机压力波数据采集系统。该系统由硅压电压力传感器、数据采集卡、PC机和基于 Labview软件的图形化用户界面 GUI( Graphical User In-terface)组成。试验证明 ,它具有结构简单、高效精确、操作简便等特点 ,在捕捉被测系统内的动态压力变化方面具有优势 ,不但能很好地满足热声驱动器的压力测量要求 。
A novel pressure measurement system applied in thermoacoustic engine is established. It consists of piezoresistive silicon pressure sensors, data acquisition card, PC and a graphical user interface which is based on Labview. Because of its simplicity, preciseness, high efficiency and maneuverability, the measurement system well satisfies the requirement of dynamic experimental study of thermoacoustic engine as well as other similar occasions.
