N2 - In the vibration environment, the pendulum displacement of the pendulous accelerometer causes loss of precision. In order to compensate for this loss, the basic network of the accelerometer system was analyzed and constructed. By analyzing the model of the accelerometer control system, a pendulum displacement model was extracted as an important factor in the design of the accelerometer system. The characteristics of the third-order correction network, the fourth-order correction network, and the fifth-order correction network were respectively simulated and analyzed. The results show that the fourth-order correction network can supply sufficient stability margin, and at the same time, the maximum pendulum displacement can be reduced to 0.563 μm in 1 g vibration, the frequency point is controlled to 151.13 Hz. The sinusoidal vibration sweep experiment of 6 g amplitude and 20 to 2000 Hz frequency was performed with the accelerometer with different correction networks. Compared with the accelerometer with third-order correction network, the maximum error of the accelerometer with fourth-order correction network was reduced from –1.71 × 10−3 to –2.87 × 10−4 g. The maximum point was increased from 105 to 166.2 Hz.
