Experimentally validated dynamic results of a relaxation-type quarter car suspension with an adjustable damper

Fuzzy Control of a Quarter-Car Suspension System

An active suspension system has been proposed to improve the ride comfort. A quarter-car 2 degree-of-freedom (DOF) system is designed and constructed on the basis of the concept of a four-wheel independent suspension to simulate the actions of an active vehicle suspension system. The purpose of a suspension system is to support the vehicle body and increase ride comfort. The aim of the work des...

Dynamic Response of 2 Dof Quarter Car Passive Suspension System (qc-pss) and 2 Dof Quarter Car Electrohydraulic Active Suspension System (qc-eh-ass)

Optimization of nonlinear quarter car suspension–seat–driver model

In this paper a nonlinear quarter car suspension-seat-driver model was implemented for optimum design. A nonlinear quarter car model comprising of quadratic tyre stiffness and cubic stiffness in suspension spring, frame, and seat cushion with 4 degrees of freedom (DoF) driver model was presented for optimization and analysis. Suspension system was aimed to optimize the comfort and health criter...

Semi-active vibration isolation of a quarter car model under random road excitations using Magnetorheological damper

Semi active control systems are becoming increasingly popular because they offer reliability of passive systems combined with high performance and versatility of active control systems but with low power consumptions. As Magnetorheological (MR) fluids can produce good controllable damping force under application of magnetic field, MR damper can be used as effective element in semiactive vibrati...

Development of a Semi-active Car Suspension Control System Using Magneto-rheological Damper Model

In this paper, the development of a semiactive suspension control of quarter car model using fuzzy-based controller has been done. The quarter car model to be used here can be described as a nonlinear two degrees of freedom system which is subject to excitation from different road profile. The semi-active control is designed as the fuzzy control inferred by using two single input rule fuzzy mod...
