冲击波存储测试系统的时基统一性研究

Research on Time Base Unification of Shock Wave Storage and Test System

针对冲击波存储测试系统时基统一性差,不能有效统一冲击波传播时间基准问题,研究一种基于光纤和卫星授时的冲击波超压存储测试系统。该测试系统采用光纤断线触发方式为多台测试系统提供统一触发信号,通过卫星授时模块实现对各个测试节点精确授时,实现多台冲击波超压测试系统的时基统一。试验表明该测试系统响应时间快,时间精度高,可以完成在统一时基下爆点时刻和冲击波来临时刻的准确测取。

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.
