Abstract

The invention relates to a multidirectional measuring device and method for three-dimensional explosive explosion pressure, and belongs to the field of explosive detonation impact wave overpressure signal measurement. The measuring device comprises a three-dimensional sensor assembling frame, a sleeve device, a pressure sensor, a data collection measuring device and an igniter; the three-dimensional sensor assembling frame is composed of a square frame, a U-shaped combination frame, an outer sleeve and a lifting hook. The pressure sensor installed inside a sensor auxiliary sleeve is fixed intothe outer sleeve through an internal rotation screw. The three-dimensional sensor assembling frame is placed into a water pool, water is adopted as a pressure transfer medium to obtain multi-directional explosion pressure signals of an explosive. The measuring device can perform multi-directional, multi-distance underwater explosion testing of various explosives, the time-space distribution condition of explosive waves of explosives is researched, and a new thought is supplied to explosive explosion pressure signal collection and measurement.

Description

technical field [0001] The invention relates to a three-dimensional explosion pressure multi-directional measuring device and method, belonging to the field of explosive detonation shock wave overpressure signal measurement, in particular to a three-dimensional explosive explosion pressure multi-directional measuring device and method. Background technique [0002] In cases involving explosive devices, especially anti-terrorism and anti-explosion cases, the possible explosion damage and explosion consequences of explosive devices are underestimated, and the awareness of safety prevention and control is not in place, which will cause casualties and economic losses. The size and orientation of the shock wave pressure generated by the explosion of different charge structures in the rock-soil medium directly affect the fracture effect of the solid medium, the damage of the surrounding rock of the excavation roadway, the shaping effect of the excavation profile surface, and the se...
