Sensor impact pressure calibration system and method in supergravity centrifugal environment

The invention discloses a sensor impact pressure calibration system and method under a supergravity centrifugal environment, the calibration system comprises a double-outlet-rod hydraulic cylinder, two inner fixing plates, two outer fixing plates, two movable pressing plates, two groups of guide rods and two groups of sensor pressure bearing platform assemblies, the double-outlet-rod hydraulic cylinder is fixed between the two inner fixing plates; a set of guide rods are fixedly connected between each inner fixing plate and the corresponding outer fixing plate, a reinforcing hoop is connected between the outer end of one set of guide rods and the inner surface of the corresponding outer fixing plate, and each movable pressing plate is slidably connected to the corresponding set of guide rods. Two piston rods of the double-outlet-rod hydraulic cylinder penetrate through the two inner fixing plates respectively and then are fixedly connected with the two movable pressing plates, and the two sets of sensor press
