The purpose of designing the active suspension systems is providing comfort riding and good handling in different road disturbances. In this paper a novel control method based on adaptive neuro fuzzy system in active suspension system is proposed. Choosing the proper data base to train the ANFIS has an important role in increasing the suspension system’s performance. The data base which is used...
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...
this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...
This paper investigates the GENSIS air spring suspension system equivalence to a passive suspension system. The SIMULINK simulation together with the OptiY optimization is used to obtain the air spring suspension model equivalent to passive suspension system, where the car body response difference from both systems with the same road profile inputs is used as the objective function for optimiza...
This paper is primarily studying the behaver of the twin-accumulator suspension over the conventional passive system focusing on ride quality behavior and road holding. Therefore, a dynamic modeling of passive and twin-accumulator suspension for a quarter model is constructed. MATLAB Simulink environment is used to develop the suspension models. The simulation is applied with two different road...
This paper introduces a novel passive suspension system for ground vehicles. This system is based on a flexible Electromagnetic Shock Absorber (EMSA). In the proposed system, efforts are made to a) select a high damping coefficient usable in a car b) determine Physical dimensions and geometry not much different from those of the mechanical shock absorbers and c) seletct EMSA weight and volume l...
Vibration suppression is considered as a key research field in civil engineering to ensure the safety and comfort of their occupants and users of mechanical structures. To reduce the system vibration, an effective vibration control with isolation is necessary. Vibration control techniques have classically been categorized into two areas, passive and active controls. For a long time, efforts wer...
This paper illustrates the mathematical modeling of passive suspension system and the control strategies for semi active suspension system. The Simulink software developed by Matlab is used to evaluate the control characteristics [1], for the same a 2 DOF quarter car model is used. The comparison and evaluation of control result are made using software-in-the-loop simulation (SILS) method. From...
1. Graduate student; 2Professor, Dept. of Mech. Eng., The University of Michigan, Ann Arbor, MI 48109-2125. 3. Principal Research Engineer, Ford Research Laboratory, Ford Motor Company, Dearborn, MI 48121. Abstract This paper addresses the coupling between the plant and control optimization problems for a suspension comprising both passive and active components. Suspension dynamics are modeled ...
The purpose of suspension system in automobiles is to improve the ride comfort and road handling. In this research the ride and handling performance of a specific automobile with passive suspension system is compared to a proposed fuzzy logic semi active suspension system designed for that automobile. The bodysuspension-wheel system is modeled as a two degree of freedom quarter car model. MATLA...
