Experimentally Study of the Cushion Materials for Micro Accelerometer under Shock Load
This work studied the cushion efficiencies of aluminum foam and metal rubber as the cushion materials for microaccelerometers under shock load. A series of shock experiments were carried out to test the performance of these two materials. Preliminary results indicated that aluminum foam and metal rubber have different energy absorption mechanisms, and both of them have excellent energy absorption capability, which can effectively cushion the effect of shocking pulse peak and suppress the high-frequency vibration noise. Aluminum foam and metal rubber are believed to be promising cushion materials for microaccelerometer.
