Research of testing technology for gun's initial disturbance based on embedded PC104 and PSD optical lever

Gun's initial disturbance influences firing accuracy of the whole weapon system directly, and it is very important to test parameters of initial disturbance exactly. At present, PSD optical lever is adopted to test the motion status of projectile in bore, but the testing system can't collect multi-parameter of initial disturbance in time. In order to satisfy require of test, software and hardware of testing system for the shell's motion status are generally relocated according to characteristic of initial disturbance. The testing system for gun's initial disturbance based on embedded PC104 bus module is designed. The exam result indicates that the testing system has high-reliability and rapid response, which can collect multi-parameter of initial disturbance and then analyze the signal.
