Study on Sensor Vibration Reduction Installation Structure with Damping Material of Ground Reflection Pressure Measurement

In blast field test, strong mechanical shock and vibration affect the output of blast pressure sensors. To avoid this phenomenon, a pressure sensor vibration reduction installation structure was designed for the measurements of ground reflection pressure. The damping material was used in the installation structure. And certain blast field test had been carried out. The data from the field blast test was compared to transducers with vibration reduction and transducers without vibration reduction. The results show that the obvious effect of the vibration reduction can eliminate vibration interference. And it is suitable for the measurements of shock wave over-pressure in blast field test.
