A test method of motion parameters of static explosion based on high-speed photography

Abstract

In order to increase the reliability to obtain fragments’ velocities and velocity attenuation coefficients in static explosion experiments, a vision-measurement method based on high-speed photography is proposed in this paper. We use high speed cameras to acquire images and visually solve the fragment trajectory. A kinematic model is then applied to fit fragments’ initial velocities and velocity attenuation coefficients. Experimental results show that the test method is valid which can considerably increase the accuracy of the data.
