This study analyzes effects of vibrations on comfort and road holding capability of vehicles as observed in variations of suspension springs, road roughness etc. Also, design of non-linear experimental car suspension system for ride qualities using neural networks is presented. Proposed active suspension system has been found more effective in vibration isolation of car body than linear active ...

and damper do not provide energy to the suspension system and control only the motion of the car body and wheel by limiting the suspension velocity according to the rate determined by the designer, T~ the above problem, active suspension systems have been proposed by various [3,4,51. Active suspension systems dynamically respond to changes in the road profile because of their ability to supply ...

In this paper design of active suspension in a half car model is presented. The idea of suspension has to improve the ride quality while maintaining good handling characteristics of three road distrubancences bump and hole, sine and random .it input have been applied to disturb the suspension system. Then PID controller for active suspension system of half car model has been simulated by using ...

In the last few years, different linear and non-linear control techniques have been applied by many researchers on the vehicle suspension system. The basic purpose of suspension system is to improve the ride comfort and better road handling capability. Therefore, a comfortable and fully controlled ride can not be guaranteed without a good suspension system. The suspension system can be categori...

In this study, Fuzzy PID Control scheme is designed for an active suspension system. The main goal of an active suspension system for using in a vehicle model is reducing body deflections and handling high comfort for a passenger car. The present system was modelled as a two-degree-of-freedom (2-DOF) nonlinear vehicle model. Keywords—Active suspension system, Fuzzy PID controller, a nonlinear q...

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...
