In the near-field blast zone experiment, strong instantaneous vibration often cause severe interference and even damage to transducers measuring shock pressure. To avoid the phenomenon, a better flexibility of isolator structure was designed. The data from the field blast test was compared and analyzed to transducers with vibration isolation and transducers without vibration isolation, and the isolator structure was verified by an inter-level segment explosive separation test. The results show that the obvious effect of the vibration isolation measures can partially inhibit or completely eliminate vibration interference.
