Theoretical Research of Measuring the Kinetic Energy for Swarm of Fragments with Six-Light-Screen Array

Abstract:

Aimed at the measurement of kinetic energy for swarm of flying fragments, a measuring method of kinetic energy for the flying fragment using six-light-screen array was presented in this paper. When a fragment pass through the six light screens, the six-time sequences, can be gathered in turn. Lots of fragments can generate some sequence of six-times. The algorithm that can distinguish the sequence from a group of sequences of time is put forward in this paper. According to the coordinates of fragment position on a position indicator as well as all the sequences of the fragments, the real time sequence can be distinguished and recognized. Then the real velocity and accurate location of the fragment can be calculated with the algorithm designed, and the kinetic energy of fragments can be measured. The algorithm is proved accurate and effective by the simulation.
