  • Method and apparatus for measuring dynamic response characteristics of shock accelerometer
    Patent number: 5000030
    Abstract: A method for measuring the dynamic response characteristics of a shock accelerometer comprises the steps of attaching an accelerometer to be tested and a strain gage to one end of a rod supported to be axially slidable, imparting an impact to the other end of the rod, inputting the acceleration arising when the elastic wave reflect from the end surface of the rod to the accelerometer and the strain gage, subjecting the outputs of the accelerometer and the strain gage to data processing and error compensation to obtain the gain and phase characteristics of the accelerometer.
