In order to meet requirements on high structural sensitivity and output sensitivity of HEMT micro-accelerometer
elastic structure of micro-accelerometer is optimized and get a new micro-accelerometer structure of fold beam.Use ANSYS finite element analysis software to simulate original structure and new structure of accelerometer.Through calculation and analysis comparison
the result shows that optimized structure of accelerometer is reasonable and meet design goal
sensitivity is an order of magnitude more than the original and output sensitivity is three times more than the original.
