摘要
主要探讨了弹药引信系统在勤务处理、发射过程、弹道飞行以及硬目标侵彻中所遇到的各种振动与冲击问题。首先,阐述了振动问题,包括有引信在运输、弹道飞行过程中所受到的振动载荷及为解决全弹道供电问题,将飞行过程中的气流振动能量转化为电能三个方面;其次,介绍了冲击问题,涵盖勤务处理过程中的意外跌落、发射过程中的后坐力、侵彻过程中的惯性过载及将冲击过载转换为引信用电能这四个方面;然后,介绍了为保证引信在振动与冲击环境中的可靠性所采取的措施,既保证引信系统在恶劣的强冲击环境中不会产生结构损伤,又保证系统不会产生误动作,提前解除保险造成危害;最后,详细阐述了为满足引信控制起爆电路和全弹道供电的需求,对引信使用过程中遇到的振动与冲击的能量的收集措施,并对引信振动与冲击问题的发展进行了展望。
This paper explores different vibration and shock problems existing in ammunition fuze system during service processing,launching,ballistic flight and target penetration.The vibration problems cover the vibration load resulted from transportation and ballistic flight,and the energy conversion of airflow vibration into the electric energy to solve the problem of full ballistic power supply.The shock problems cover the accidental fall during the service process,the recoil during the launch,the inertia overload during the penetration process,and the conversion of the impact overload into the electric energy.A series of measures that must be taken to ensure the reliability of fuze in shock and vibration environment were discussed.Neither structural damage nor premature releasing malfunction should be caused by the harsh impact environment.Also,the measures for converting the energy of vibration and shock energy to electric energy to meet the requirements for the fuze control detonating circuit and full ballistic power supply are discussed.Finally,the development of fuze vibration and shock problems is prospected.
