摘要
主要介绍了一种高瞬态、宽谱的膛压准静态信号的测量方法及其在强电磁干扰环境下采取的抗干扰措施。引入了声腔滤波技术和光电隔离技术，并使用石英压力传感器和ＰＶＤＦ压力传感器进行了实验验证。为电热炮、液体炮等先进驱动系统的高瞬态、宽谱的膛压测量提出了一种有效的方法。
This article reports the measurement method of the pressure in bore with high transient and broad spectra.It also presented how to resist the strong electromagnetic disturbances.The measurement method includes the acoustical filter and opto electric separation techniques.The quartz and the PVDF pressure transducers,which are used in the experiment,are showed to be an efficient one for measuring pressure with high transient.The measuring results show that the method is practical and efficient.
