“…The straight red line is the ideal case between the amplitude of self-induced voltage and damper displacement; it indicates that the experimental dots in the same damper displacement under different dc inputs were scattered close to the trend line. This means the amplitude of self-induced voltage was proportional to the damper displacement and has a good repeatability, while in our previous works [38,39], the repeatability of the selfinduced voltage under different dc inputs was not good due to a bias at the zero damper piston displacement; the bias is 0.016 V at 0.25 A and 0.047 V at 0.5 A, respectively.…”

“…Our group also developed a self-sensing MR damper based on electromagnetic induction whose performance was evaluated with simulation analysis [37], but since only one self-sensing coil was wound onto the winding cylinder, the accuracy of the self-sensing ability must be increased. Later on, our group developed and fabricated a novel displacement differential self-induced MR damper [38,39], where two differential self-induced coils were wound onto a winding cylinder in order to obtain a more accurate output of selfinduced voltage that would be proportional to the damper's relative displacement. Furthermore, some works were conducted to investigate the effects of flux leakage, the winding cylinder with different but basic values of structure parameters and materials on the self-induced performance of the MR damper.…”

This work is an extension of our previous study on the development of a linear variable differential sensor (LVDS)-based magnetorheological (MR) damper with self-sensing capability, where a new MR damper integrated with LVDS technology was developed and prototyped, then its self-induced performance under static and dynamic working conditions was experimentally evaluated. The results of the static and dynamic experiments indicated that the self-induced voltage was proportional to the displacement of the damper. Moreover, the damping performance of this new MR damper was also evaluated through an experimental study. Compared with our previous study, the new MR damper performed better in terms of its self-induced sensing ability and damping capacity.

Aiming at the detection of the sucker rod defects, a real-time detection system is designed using the non-destructive testing technology of magnetic flux leakage (MFL). An MFL measurement system consists of many parts, and this study focuses on the signal acquisition and processing system. First of all, this paper introduces the hardware part of the acquisition system in detail, including the selection of the Hall-effect sensor, the design of the signal conditioning circuit, and the working process of the single chip computer (SCM) control serial port. Based on LabVIEW, a graphical programming software, the software part of the acquisition system is written, including serial port parameter configuration, detection signal recognition, original signal filtering, real-time display, data storage and playback. Finally, an experimental platform for the MFL detection is set up, and the MFL measurement is carried out on the transverse and longitudinal defects of the sucker rod surface. The experimental result shows that the designed acquisition and processing system has good detection performance, simple design and high flexibility.

“…The concept of self-sensing refers to the capability of one mechanical system to measure and deliver dynamic information in real time using the self-contained component of the system without the requirement for extra sensors [18][19][20]. For instance, the self-sensing technology for the self-induced velocity, displacement, and forces has been developed and feasible in the magnetorheological (MR) damper [21][22][23][24][25][26]. The practical implementation of the self-sensing feature embellishing the MRE absorber, however, has been rarely investigated according to the best knowledge of the authors.…”

In this paper, self-sensing technology was introduced into an adaptive tuned vibration absorber, incorporating a laminated magnetorheological elastomer (MRE) structure, a hybrid magnetic system and a self-sensing component. The adoption of the laminated MRE structure and the hybrid magnetic system enables the absorber to have higher lateral flexibility and a wider effective frequency range. The integration of the selfsensing capability allows the absorber to operate without sensors and, at the same time, greatly reduces costs, required space and maintenance. A series of experiments were conducted to measure the frequency shift property, to verify the self-sensing capability and to evaluate its effectiveness on vibration reduction. The experimental results show that the natural frequency of the proposed absorber can be changed to 4.8 Hz at -3 A and 11.3 Hz at 3 A from 8.5 Hz at 0 A, the frequency of the self-sensed voltage equals the excitation frequency and, more importantly, the vibration control effectiveness of the self-sensing MRE absorber is experimentally verified and it is more effective on vibration reduction than a passive absorber.

The adoption of the laminated MRE structure and the hybrid magnetic system enables the absorber to have a higher lateral flexibility and wider effective frequency range. The integration of the self-sensing capability makes the absorber leave out the usage of sensors and at the same time is a big relief on the cost, space, and maintenance.A series of experiments were conducted to measure the frequency-shift property, to verify the self-sensing capability, and to evaluate its effectiveness on vibration reduction.
