Design analysis of force balance accelerometer

LI Cai-hua~(1, 2)(1.Inst of Engin Mechanics,China Seismological Bureau,Harbin 150080,China;2.Harbin Beiao Vibration Technology Co.Ltd.,Harbin 150080,China)  
Principle of force balance accelerometer based on differential capacitance is introduced.Movement function of accelerometer is calculated,and three key specifications of accelerometer,natural frequency,damp and amplitude response,lie on three components.The three components are mass m,proportional resistance R,differential capacitance C.Natural frequency,bandwidth,output sensitivity of accelerometer are determined by the three components.
