摘要

针对深水炸弹水下爆炸威力毁伤测试试验时现有全备引信不能满足试验使用需求的问题,在原全备引信的基础上开展了一种安全型的起爆试验用引信设计研究。该引信结构主要由密封保险、水压保险和辅助保险机构等组成。通过采用非线性有限元软件AUTODYN进行数值仿真分析和水下解除保险试验验证相结合的方法,对密封保险机构中电雷管炸通密封结构进水口过程进行了数值模拟分析和试验验证,数值模拟与试验验证结果基本一致。试验引信通过跌落、运输、振动和水下起爆试验验证,结果表明:该试验引信能够满足勤务处理安全性要求,能够较好地解决深水炸弹水下爆炸试验中操作安全和工作可靠问题,具有一定的工程应用价值,可向其他类似水下爆炸试验推广应用。

Abstract

Aiming at the problem that the assembled fuze in active duty can not meet the test requirements during the underwater explosion damage test of a depth bomb, an safe fuze for detonation experiment is designed based on the original assembled fuze. The structure is composed of sealing arming device, limit water pressure arming device and auxiliary arming device etc. By using the nonlinear finite element software AUTODYN for numerical simulation analysis and underwater arming test verification, the process of the electric detonator exploding through the water inlet of the sealing structure in the sealing arming device is used to simulate and test, the results of experiment and numerical simulation are basically consistent. The fuze has been verified by drop, transportation and underwater explosion tests, it shows that the improved fuze can meet the requirements of fuze safety for handing of fuze, it can better solve the problems of safe operation and reliable operation in the underwater explosion test of deep-water mine bomb, and it has certain engineering application value and can be applied to other similar underwater explosion tests.
