Abstract:
T he paper describes the w orking principle of magnetic-electric sensor in safety airbag of automobile. Structure and elect ric circuit of this sensor is designed and impact ex per-i ment for this sensor is simulated. In the paper the sensor has a w ide range of measurement . The accelerat ion peak value is from 0 to 588 m/ s2, w idth of time pulse is from 0 ms to 20 ms. Ident ificable elect rical circuit has dual discriminat ion characteristics of peak value and t ime. It is a new kind of sensor used in safety airbag of automobile.
