用光电技术测定爆轰参数

DETERMINATION OF DETONATION PARAMETERS WITH OPTICAL-ELECTRICAL TECHNIQUE

本文介绍了一种用光电技术同时测定爆速和爆温、爆压和爆温的方法。用光电比色技术测定炸药爆轰温度的同时,用两个爆轰面上爆轰的时间差计算爆轰波速度;或用透明介质中冲击波速度来反算炸药中的爆轰压力。方法原理可靠,技术简便。

A method of simultaneously measuring detonation velocity and temperature, or detonation pressure and temperature by optical technique is presented in this paper. While detonation temperature is determined with a transient optical-elec -trical two-colour pyrometer, the detonation velocity can be obtained by measuring the time difference of detonation wave arriving at the two surfaces of the explosive charge, and the detonation pressure can be obtained by measuring the shock velocity in a transparent medium which is contact with the end of the charge. The method is both reasonable and simple and can be widely used in experimental investigation of detonation and explosion effect.
