Real-Time Sensing Action of the Electromagnetic Vibration-Based Energy Harvester for a Magnetorheological Damper Control

Abstract

This study investigated the self-sensing mechanism in the electromagnetic vibration-based energy harvester (EV-EH) prototype specially engineered for a commercial magnetorheological (MR) damper. The objective of the work is to demonstrate that the EV-EH unit with a specific self-powered feature can also be employed as a relative velocity sensor in the system. To do this, the self-sensing action of the unit was experimentally studied over the assumed range of working conditions. The analysis of the test results and the determined self-sensing function indicated that the EV-EH has a highly accurate monitoring capability. The EV-EH self-sensing and self-powered features confirm the potentials and applicability of the unit for MR damper control in a vibration reduction system with energy regeneration.

Focus Estimation Methods for Use in Industrial SFF Imaging Systems

“…The method based on the maximum function proves sufficient for most cases considered. The absence of floating-point calculations results in less computing power and the possibility of using hardware acceleration methods [33][34][35]. The CoG method allows for the increased resolution in the z-axis.…”

Adaptive optimal fault-tolerant vibration control and sensitivity analysis of semi-active suspension based on a self-powered magneto-rheological damper

“…Sapiniski and Orkisz [8] investigated the self-sensing mechanism of a self-powered MR damper. Via theoretical analysis and experiment validation, the mechanism exhibited highly accurate monitoring capability, which can be regarded as a velocity sensor.…”

Research on energy-regenerative suspension based on WOA-PID algorithm

“…To address the problems of magnetorheological dampers (MRDs), which requires the constant supply of electricity, the study on MRDs with multiple functions has become the a major trend in this field, leading to the emergence of MRDs with the function of relative displacement self-sensing (IRDSMRD) (Guan et al, 2019), self-powered MRDs (Sapin´ski and Orkisz, 2021), and the abilities of harvesting energy (Hu et al, 2020). The piston rods of MRDs always reciprocate, up and down, such that mechanical energy can be transferred into the thermal energy dissipated into the air (Liao et al, 2019).…”
