摘　　要：通过测试某直列式起爆装置的瞬发度、解保时序安全性、冲击片雷管输出能力,研究该型起爆装置是否满足武器装备的要求。设计了一种用于模拟平台的解保指令及起爆指令的测试工装,以及一种可重复使用的雷管替代品。通过测试工装模拟平台的起爆编码,使用稳压源模拟平台为起爆装置提供工作电压,利用示波器查看从起爆指令给出到雷管起爆过程的时间差,测量起爆装置的瞬发度。当工作电压在20~32.6 V时,起爆装置瞬发度的分布范围在31.7~40.6μs,平均瞬发度为34.50μs,测得的瞬发度远小于系统所要求的250μs;该直列式起爆装置在接收到5种共50次异常解保信号下均不会起爆;根据钢块凹痕法(GJB 736.3—1989),利用钢块测定冲击片雷管的输出能力,凹痕深度在1.32~1.52 mm,满足指标要求。研究表明,该直列式起爆装置在较宽的工作电压范围下具有较好的一致性,在调试和使用中具有良好的安全性,并且在起爆冲击片雷管时具有良好的可靠性。基于直列式起爆技术的新型起爆系统满足武器装备的要求。同时所设计的电子安全解保测试工装能准确模拟具有不同判别时间窗的各通道的解保功能,并能安全可靠地按照平台的要求输出点火电流。This paper studies whether the in-line detonation device can meet the requirements of weapons and equipment by testing some properties such as the instantaneity, the safety of the arming sequence, and the detonation capability of the slapper detonator. We designed a test fixture with the function of simulating the safety ignition current and a detonator substitute to test the instantaneity. We inputted the initiating code through the test tool which simulated the platform, used a UVS(Universal Voltage Source) to simulate the working voltage of the platform, and used the oscilloscope to view the voltage waveform from the test tool outputting initiation command to the detonator being ignited, to measure the time interval of the process, which is the instantaneity of the detonation device. When power supply voltages were 20-32.6 V and instantaneities of the detonation device were 31.7-40.6 μs, the average transient was 34.50 μs which is far lower than the 250 μs required by the system. The detonation device didn’t output ignition circuits after receiving 5 kinds of abnormal arming signals 50 times. According to the Method of Steel Dent(GJB 736.3—1989), the output capacity of the slapper detonator was determined by using the steel target. The depths of steel dents were 1.32-1.52 mm, which meets the expected standard. The results show the in-line detonation device has a good consistency under a wide range of working voltages, has good safety in the process of commissioning and using, and has good reliability when igniting a slapper detonator. Besides, the results show the designed test fixture can accurately simulate every arming channel with a different discriminant time window and can output an ignition current according to the demands of platform safety and reliability. The test research indicates that the new system based on in-line detonation technology meets the requirements of weapon equipment, and contributes to the further promotion of in-line technology in China.
