Abstract

In order to solve the problem that the shock wave storage and testing system has poor time base unity and cannot effectively capture the burst point time and the shock wave propagation time, a shock wave overpressure storage and testing system based on optical fiber and satellite timing is studied. The test system provides a unified trigger signal for a plurality of test systems by adopting an optical fiber disconnection trigger mode, realizes accurate time service for each test node through a satellite time service module, and realizes time base unification for a plurality of shock wave overpressure test systems. The test results show that the test system has fast response time and high time precision, and has completed the accurate measurement of the explosion point time and the shock wave arrival time under the unified time base.

Key words： shock wave test; uniform time base; optical fiber technology; satellite clock
