摘要
脉冲防暴水炮射流的非稳态特征和较大的雾场范围,增加了对其雾化特性进行测量的难度。通过分析当前激光雾场测量技术的基本原理和方法,指出粒子图像速度粒径(particle i mage veloci metry and sizing,PIVS)方法适合脉冲防暴水炮射流雾化特性的测量。根据脉冲防暴水炮的射流特点,提出了基于粒子散射、激光片光成像和高速摄影技术的测量方法,并对硬件系统的设计进行了分析,为下一步试验台的搭建提供了理论指导。
It is the non-steady characteristic and large water mist field of impulse anti-riot water cannon that increases the difficulty of measuring atomization characteristics.Through analyzing the basic theory and method of modern laser measuring technologies,the PIVS method is deemed to be suit for measuring the atomization characteristics of impulse anti-riot water cannon.According to the water jet characteristics,the measuring method based on the technologies of particle scattering,sheet laser imaging and high speed handling are proposed and the designation of hardware system is analyzed which provides theoretical instruction for the setting up of test bed.
