“…The reported results concern a MR damper [9] system installed on a commercial motorcycle (see Fig.4). Each suspension is composed by a MR damper (3000N maximum force at 500 mm/s), a spring (K=85N/mm), a fork composed by: a cartridge with 1000N of maximum damping force at a 1000 mm/s and two springs with k=90N/mm), two potentiometers and a control unit for the control strategy.…”

Active and semi-active suspension systems allow to obtain the best compromise between ride comfort and road holding. These systems analyze signals describing the vehicle status and react to unwanted vibrations on the basis of the control strategy. The analysis of the signals in the frequency domain can improve the control action, since incoming vibration can be properly detected. In this paper a method for the detection of incoming frequency components in real-time is proposed and is used in analyzing a Magneto-Rheological suspension system.

“…When an external magnetic field is present, the MRF particle will form linear chains parallel to the field due to the dipole moment of particle aligned with the magnetic field. This will solidify the MRF and restrict the movement of the fluid [3]. Few types of model were developed to represent the behavior of MR damper.…”

Magnetorheological fluids (MRF) are considered as smart material since the behavior of the fluid is interrelated with external magnetic field. The rheological behavior of the fluids is changed whenever the strength of magnetic field changed. One of the applications of MRF is Magnetorheological damper (MRD), a damper that can be controlled by magnetic field. Analytical model of the damper is important in order to understand the performance of MRD. Different types of model that depend on defined parameters were introduced by previous researchers, and investigation on those parameters is crucial to acquire a model with least value of error. A technique called nonlinear least squares fitting method is utilized in order to obtain those parameters. This study investigated five different MRD models and presents the result for parameter estimation for each model as a function of input current.

“…It is due to the fact that changes in geometry of the flow paths in real time require rather complex actuation mechanisms to be incorporated in the mount. However, it has been highlighted by several researchers that as a fluid filled mounting components, MRF still open to some drawbacks such as shortcoming of particle sedimentation because of density mismatch between particles and the carrier fluid (Stefan and Kajaste, 2011), achievable yield stress, the stability and durability of the fluid (Acocella et al, 2010), settling due to differences in specific gravities and wear of the magnetic particles (Jerzy, 2012).…”

This paper presents the modelling and validation of three degree of freedom of engine mount system. The engine mounting system successful to isolate the driver and passenger from the noise and vibration, but there is a need to improve the performance of engine mount system due to current modern car design which required lighter car body, higher speed and lar power-intensive engine. The passive rubber has been modelled as spring and damper in parallel. Based on Newton's Second Law, the mathematical equation has been derived out and implemented into MATLAB Simulink for the validation purposes. A real experim from engine mount system has been used as the benchmark in this study. The response of the acceleration from the real system has been compared with the simulation result. Pe difference of 3.9 to 5% has been obtained for the simulated mod experimental result.
