Design, Analysis, and Experimental Validation of a Variable‐Gap Magnetorheological Damper for Seat Suspension

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT To address the dual challenges of routine driving vibration and impact loads in vehicle seat suspensions, a novel variable‐gap magnetorheological damper (VGMRD) is proposed. By combining a tapered piston with a conformal variable‐diameter cylinder, stroke‐dependent, dual‐mode damping characteristics are achieved without the need for complex ...

A Three‐Phase Electrostatic Clutch with Variable Mechanical Impedance Control for Soft Robotic Systems

Advanced Science, Volume 12, Issue 45, December 4, 2025.
The research introduces a three‐phase electrostatic (ES) clutch with variable mechanical impedance control, specifically designed to enable continuous and precise friction modulation, thereby reducing both force degradation and oscillatory motion. This method effectively resolves conventional ES clutch issues, such as residual charge accumulation and ...

Control of Semiactive Suspension Systems Using Preview Information and Convolutional Neural Networks

Shock and Vibration, Volume 2025, Issue 1, 2025.
Due to the complexity and variability of road conditions during vehicle operation, the ability of suspension systems to effectively suppress vehicle vibrations is often limited. To enhance ride comfort of the vehicle across varying road surfaces, a preview control strategy is designed based on the convolutional neural network (CNN) and skyhook control ...

Influence of temperature and internal leakage on magnetorheological damper

International Journal of Mechanical System Dynamics, Volume 4, Issue 4, Page 487-496, December 2024.
Abstract To study the influence of temperature and internal leakage on the performance of magnetorheological (MR) damper, a single‐rod straight‐cylinder MR damper with an inside temperature sensor is designed in this study. A unified model for MR damper is given, and a new two‐step parameters identification method is proposed to determine model ...

A Robust Vibration Control of a Magnetorheological Damper Based Railway Suspension Using a Novel Adaptive Type 2 Fuzzy Sliding Mode Controller

Shock and Vibration, Volume 2017, Issue 1, 2017., 2017
This work proposes a novel adaptive type 2 fuzzy sliding controller (AT2FC) for vibration control of magnetorheological damper‐ (MRD‐) based railway suspensions subjected to uncertainty and disturbance (UAD). The AT2FC is constituted of four main parts.
