Abstract

A novel vibration sensor based on a bio-inspired nonlinear structure with quasi-zero stiffness (QZS) characteristic is developed for the real-time measurement of absolute vibration motion. With this bio-inspired vibration sensor, the problems of error accumulation and real-time performance induced by traditional measurement method using accelerometer can be effectively eliminated. Through taking full advantage of the bio-inspired vibration sensor in real-time measurement of absolute vibration motion, a model-based fault detection algorithm is proposed to cope with the on-line detection problem of weak fault with fast time-varying characteristic, which can not be solved by existing frequency-based and wavelet-based fault detection methods. Some results demonstrate that the fault detection algorithm based on this bio-inspired vibration sensor is effective.
