组合式生物激波管的研制及应用

Development of a Constant/Divergent Combined Biological Shock Tube and its Employment

本文报道了等变/截面组合式生物激波管的结构,并进行了压力传感器动态标定。动物试验表明,弱激波条件下,本设备的超压峰值和正压时可导致豚鼠鼓膜穿孔、大鼠轻度直至致死性冲击伤。该激波管具有组合方式多、模拟多种爆炸波的能力强、使用费低等特点。

The structure of a combined shock tube newly developed in our laboratory and its employment in the dynamic calibration of pressure transducers, the study of airblast-induced auditory injury of 105 guinea pigs and blast injures in 70 rats are descirbed. The results indicate that the deviations of overpressure peek value and positive duration of the shock waves generated by the device are less than ±1.6kPa and ±1.0msec. respectively with the characteristics of more configurations, higher potentiality of simulating various explosive waves, lower expense and simple operation.
