System Optimization Algorithm for 3DOF Quarter Car Active Suspension

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...

Comparative Analysis of Passive and Semi-Active Suspension System for Quarter Car Model using PID Controller

In this paper the importance of self tuning adaptive PID control scheme for automotive suspension system is explained. The objective of this study is to obtain a mathematical model for the passive and semi-active suspension system for quarter car model. Current automobile suspension system employs springs and damper with fixed coefficient. Vehicle suspension systems are typically rated by their...

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...
