Impact Hammer Calibration System

It consists of a standard impact accelerometer, a pendulum, a pendulum clamping and releasing mechanism, a standard mass block, a mass block suspension mechanism, a dynamic data collector and a testing software. Through the collision between the pendulum and the standard mass block, the outputs of the reference accelerometer and force sensor are tested, and the conversion of acceleration and force is realised through F=MA to calibrate the dynamic force sensor sensitivity, linearity and other indexes. By adjusting the fall height of the pendulum, different ranges of calibration and linearity testing can be achieved.
Pulse width: 0.1ms-50ms (adjustable); Mass block: about 1kg; Impact acceleration: ≥1000g; Impact force: ≥10kN.
