摘　　要：传统航天器发射前会进行大型专项发火试验,验证火工品起爆线路设计的正确性,由于采用真实火工品,存在危险系数大、试验经费高、起爆参数测试难度大等问题。为有效减少上述问题,设计研发了一种发火线路电子等效测试装置,不仅能够模拟真实火工品完成发火试验基本测试内容,还可以实现起爆后火工品线路故障的在线注入。同时,该装置可以重复使用,降低了试验成本,对其他航天型号火工品及发火线路测试工作具有借鉴意义。Special fire test is implemented before the launch of the spacecraft to verify the correctness of the design. Due to the usage of a real initiating explosive device, there are many problems, such as the high risk factor, the high test cost and the difficulty of the initiating parameter test. Aiming at avoiding these problems, a firing line electronic equivalent test device is designed and developed, which can not only simu- late the explosive high reliability of the complete firing test basic test content and also can realize online after initiation explosive line fault injection. At the same time, the device can be used repeatedly and the test cost is reduced. The utility model can be serve as reference for testing work of other aerospace types of initiating explosive devices and ignition lines.
