Design and development of MR damper for two wheeler application and Kwok model parameters tuning for designed damper

Abstract

Magnetorheological dampers have been the interest of many researchers for a few decades for the reason of being an effective and rapidly progressing technology in the field of semi-active controlled suspension. The dynamic behaviour of these devices with nonlinear hysteresis is quite a complicated phenomenon. Hence, this paper aims at the design, modelling and simulation of a custom-made MR damper for a two-wheeler vehicle. The Kwok model has been chosen to mathematically model the MR damper. The model parameters have been optimised by minimizing the error difference between experimental and model-generated force results. A PID control is designed to control the damper effectively depending on the deflection of the damper. The two-wheeler vehicle modelled with four degrees of freedom is coupled with a mathematical model of MR damper in front and rear suspension. Further, the dynamic analysis has been performed in MATLAB/Simulink considering random road input for different velocities and current input conditions. The improved performance of MR damper was observed in suppressing road irregularities using a PID controller. As an implementation part of the work, the developed damper has been implemented in a two wheeler vehicle for performance evaluation at on-road testing conditions. The results showed significant improvement in damper performance with increment of constant current controlling MR dampers.

Experimental Investigation and Numerical Prediction of Magnetorheological Damper Behaviour

“…Magnetorheological fluid (MRF) is a class of intelligent materials that may modify their rheological behavior in response to the application of an external magnetic field and has been widely used in numerous complex systems across numerous technical disciplines [2]. Today, magnetorheological dampers are used in a variety of vibration control applications in real-world settings, and MR dampers are being used in multiple projects [3][4][5][6]. The usage of MR Dampers reduces the dynamic vibration forces that arise in the structural elements and increases their life efficiency [7][8][9].…”

“…Thus, MR fluid is increasingly investigated in semi-active application systems to take its great intrinsic advantage of continuous controllability in a wide dynamic range. MR fluid-based devices can be found in various industrial fields such as structural protectors (Abdeddaim et al, 2022; Bagherkhani and Baghlani, 2021; Rayegani and Nouri, 2022; Weber, 2014), actuators (Diep et al, 2021; Kaluvan et al, 2016; Kikuchi et al, 2021), vehicle suspensions (Bai et al, 2013; Devikiran et al, 2022; Du et al, 2020; Oh et al, 2021), and trains (Bhardawaj et al, 2020; Guo et al, 2015; Hua et al, 2022). For washing machines, several scholars have performed researches on semi-active suspension systems using MR dampers (Bui et al, 2018; Carlson, 1999; Nguyen et al, 2014; Spelta et al, 2009; Ulasyar and Lazoglu, 2018).…”
