In order to adapt to the environment of random vibration and high shock

for the leveling equipment based on 2-axis quartz accelerometer

a design method of the support structure and inherent frequency of the accelerometer which has the structure of three beam single isle and double beam single isle is introduced

and the design result is analyzed by finite element method and proved by vibration and shock examination.The results show that the accelerometer structure designed by this method can adapt the environment of random vibration and high shock well and the measurement accuracy is 0.02°after the random vibration 0～2 kHz and（1 10 g

n

） shock for（3 ms）.
