摘　　要：结合航天发射场实际,介绍了整流罩横向分离的关键技术。阐述了爆炸螺栓的工作原理,以及电起爆器的工作过程。建立了整流罩横向分离系统工作的数理模型并进行了仿真,获得了详细的数据,得出了多路电起爆器工作的时间差;对整流罩横向分离的同时性进行了分析,给出了相关结论。结果表明:整流罩横向分离的时间差在毫秒级,并且通过适当增大电压或调整电缆连接长度与方式,可以进一步减小分离时间差,提高分离同时性水平。Combining with working practice of space launch site,this paper introduces the key technology of fairing＇s transverse separation,describes the operating principle of explosive bolt and the working process of electric initiator.This paper establishes the numerical model of fairing＇s transverse separation system and gets detailed simulation data,obtains operating time difference of multiple electric initiator,also analyzes the simultaneity of fairing＇s transverse separation.The results show that the time difference of fairing＇s transverse is in milliseconds,it can be reduced by increasing the voltage appropriately and changing wire length and its connection.
