摘要：
Parameter repeatability is a serious problem for manufactured quartz flexible accelerometer, which greatly determines the precision of measurement results. This paper presents a testing method for quartz flexible accelerometer under closed-loop condition, which helps protect pendulum. Testing results are processed by cross correlation algorithm which significantly improves the signal-to-noise ratio. Based on this, the least squares modeling method in frequency domain is given. The experiment and identification results indicate that the modeling method has advantages of high precision and practical engineering value.
