A novel velocity self-sensing magnetorheological damper: Design, fabricate, and experimental analysis

Abstract

This article presents the development of a novel magnetorheological damper with velocity self-sensing capability. The velocity self-sensing mechanism, based on the optical tracking technology and numerical circuit technology, was adopted. The configuration and work principle of the velocity self-sensing magnetorheological damper were presented. The self-sensing circuits, built with optical mouse sensor and microcontrollers, were integrated into the hollow upper lid. The hollow upper lid provides a suitable place for the self-sensing circuits, can be installed and disassembled easily, and can be maintained efficiently. The velocity self-sensing magnetorheological damper prototype with 10 kN capacity was theoretically analyzed, fabricated, and investigated. Finally, the damping performance, self-sensing performance, and self-sensing control capability were tested and analyzed. The results indicated that self-sensing velocity unit has high accurate monitoring capability over a wide range of working conditions. The velocity self-sensing magnetorheological damper–based control system has sufficient ability to control the magnetorheological damper.

A multi-pole magnetorheological clutch powered by permanent magnets and excitation coils

“…Xuan PD et al (2018) designed a new inside multi-coils clutch with an approach to produce more uniform magnetic field using the Helmholtz coil setup and placing the other coils inside of the braking disks. Guan et al (2019) proposed a novel MR damper with velocity self-sensing capability. Choi et al (2015) developed a novel haptic master using MR fluid which integrated the haptic master with a vision device with image processing for robot-assisted minimally invasive surgery.…”

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).…”

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

“…Xinchun et al [22] presented the MR damper equipped with a vibration energy harvesting mechanism based on a DC generator, ball-screw and rotary of a permanent magnet indicated the self-powered capability of this configuration. Guan et al [23] demonstrated high accuracy monitoring capability of the MR damper with a novel velocity self-sensing mechanism.…”
