“…However, since the focus of this review is on MRE durability, only MRE review articles were considered. In the same range of publication years and searched databases, review articles on MRE were identified at 16 exclusive informative articles [1], [29], [38]- [51], which four [39]- [43] were specifically reviewed on the MRE applications.…”

Most parts of the failures in structural elements in use were consequences of mechanical durability. Therefore, durability had been one of the critical factors to be considered in designing durable mechanical elements. In magnetorheological elastomer (MRE) materials, the durability process involves different damage mechanisms that result in the degradation of the materials. Increasingly used of outstanding performance of MRE was susceptible to failure under durability performance for various applications. In response to these problems, with limited sources of published articles on MRE durability, an overview of the durability of elastomer based MRE is presented. The study focuses on collecting and analyzing the works including experimental and modeling approaches that have been conducted on MRE durability up to date. Two bibliographic searched databases, Scopus and Web of Science were consulted to collect the final set of articles with the aims to identify current and future trends of MRE durability. Prominence works conducted on MRE durability were also encapsulated in this paper to provide a visual perspective and subsequently motivate researchers to heighten the need for MRE durability investigation.

“…S Gad et al 14 have designed the PID system controller tuned by genetic algorithm (GA) to achieve the desired damping force for the seat suspension and evaluated vibration control performance showing driver head acceleration and seat travelled distance in time and frequency domains. S M. Savaresi, et al 15 have developed an ideal skyhook control system which can easily be implemented in a real-time application, and M Ramalingam et al 16 have investigated several control policies for MR damper based seat suspension system including PID controller and fuzzy logic controller. They also studied 3-DOF seat suspension system installed with MR damper focusing on the minimization of the vibration transfer from the road to the seat cushion and backrest.…”

In this study, the vehicle seat suspension system installed with a semi-active magnetorheological (MR) damper is excited by the power spectral density (PSD) and its vibration control performance is evaluated using finite element analysis (FEA). The control system receives the velocity of the sprung and unsprung mass from the seat mounting locations and calculates the desired controllable damping forces available from MR damper. The effectiveness of the control systems is demonstrated by adopting ride quality evaluation method. To predict a better ride comfort and ride quality, co-simulation methodology is utilized considering the dynamic behavior of the real-world seat system. In this case, the multi-body dynamics and control system are coupled by solving the mechanical equations and the control logic. Then, the computed damping force is exchanged between the dynamics and controller in an iterative manner by passing state variables. The simulation results achieved from co-simulation methodology associated with the controller are analyzed by comparing with ISO 2631-1. The co-simulation results studied using vibration dose value (VDV), crest factor (CF) and seat effective amplitude transmissibility (SEAT) in terms of percentage improvement were found to be 44.33%, 26.66% and 17.65% respectively which were better than that for the passive suspension for a random rough road profile. Modified skyhook controller delivers superior performance for vibration suppression of the vehicle seat suspension as compared to other control policies. The application of co-simulation methodology can reduce time and cost for the development of a semi-active seat suspension system.
