Anti-Overload of a High-G Acceleration Sensor
High-g acceleration sensors are used in high-impact environment, the ability of resisting high-overload is demand higher requirements.In order to determine the Shock-resistibility of the sensors, tests were performed using Hopkinson bar. Analysis of the failure mechanism of the sensor.The results show that the critical load resulting in sensor failure is about 200000g. Main failure mode of the sensor chip is broken.
