“…The Electromagnetic Balanced Accelerometer, though not comparable to the electrostatic accelerometer, improves a lot in the accuracy and measurement range as the processing technology develops. One example is the Quartzose Flexible Accelerometer (QFA), which has a high accuracy and anti-interference ability in low-frequency and low-g environments [ 14 ]. On the other hand, the miniaturization of electromagnetic accelerometer allows it to possess smaller sizes and lower costs [ 10 ].…”

Force producer is one of the core components of a Wire Suspended Micro-Pendulum Accelerometer; and the stability of permanent magnet in the force producer determines the consistency of the acceleration sensor’s scale factor. For an assembled accelerometer; direct measurement of magnetic field strength is not a feasible option; as the magnetometer probe cannot be laid inside the micro-space of the sensor. This paper proposed an indirect measurement method of the remnant magnetization of Micro-Pendulum Accelerometer. The measurement is based on the working principle of the accelerometer; using the current output at several different scenarios to resolve the remnant magnetization of the permanent magnet. Iterative Least Squares algorithm was used for the adjustment of the data due to nonlinearity of this problem. The calculated remnant magnetization was 1.035 T. Compared to the true value; the error was less than 0.001 T. The proposed method provides an effective theoretical guidance for measuring the magnetic field of the Wire Suspended Micro-Pendulum Accelerometer; correcting the scale factor and temperature influence coefficients; etc.

Aiming at the fuzzy cognition of the key process parameters that affect the accelerometer hysteresis performance in the assembly and manufacturing process, a sensitivity analysis method for the influencing factors of accelerometer hysteresis based on Morris screening method was proposed in this paper. Firstly, the assembly and manufacturing process parameters and their range of values of core structure pendulum components are analyzed statistically. Secondly, the mean value and variance of the basic factors of each parameter are obtained based on finite element numerical simulation method. The results show that the bonding Angle between the pad I and the pendulum plate and the bonding Angle between the counterweight and the pendulum plate have the greatest influence on the hysteresis performance of the accelerometer. The interaction between the counterweight and the bonding Angle and other parameters is the most nonlinear.
