In view of the fact that the specific time of arming can not be obtained when testing the arming of fuze safety system at home and abroad at present, and there are some problems such as cost and repeatability, a testing system based on the dynamic arming time of fuze safety system is proposed. In this system, the mechanical signal is transformed into electrical signal by micro switch, laser and photodiode, and the millisecond level accurate timing of dynamic arming time of fuze safety system is realized. Through the design of start, timing, stop modules and display modules, the calculation and display functions of the actual arming time of fuse components after dynamic simulation are completed. The test and data analysis show that the measurement accuracy of the test system is high and the error is small, which meets the accuracy requirements.
