摘　　要：针对双桥电起爆器钝感要求,使用桥带升温数学模型和三维建模编程的方法,进行了相关结构设计及性能试验验证。研究表明:采用防静电板和接线板的结构设计,防静电性能稳定,能够承受16 A直流电流的冲击而不失效;当桥带厚度为0.02 mm、桥带宽度为0.32 mm时,能够满足桥路熔断时间不大于60 ms的要求;锆/高氯酸钾和D8型硼/硝酸钾点火药配合使用,能够满足安全电流1A、1 W、5 min的要求,且发火可靠。In response to the insensitivity requirements of the double-bridge electric detonator,the structural design and performance testing verification were carried out using the bridge belt heating mathematical model and 3D modeling programming method.The results show that the electric detonator with a structure of anti-static board and terminal blocks has stable anti-static performance and can withstand the impact of 16 A direct current without failure.When the thickness of the bridge belt is 0.02 mm and the width of the bridge belt is 0.32 mm,it can meet the requirement of bridge circuit melting time not exceeding 60 ms.The combination of zirconium potassium perchlorate and D8 boron/potassium nitrate ignition can meet the safety current requirement of 1 A,1 W,5 min,and the ignition is reliable.
