Study on the Pressure Test System of Blast Wave Based on Fiber Pressure Sensor

摘要

In order to solve the failure problem of traditional piezoelectric type pressure sensor due to the rapid fatigue and overload of high frequency and intense pressure impulse, a pressure test system of blast wave based on fiber pressure sensor is designed. The response mechanism of fiber pressure sensor, system constitution and action mechanism are given out. The test system has been applied with repeated pressure test, the result prove that it is reliable.
