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.
