[Avesta Goodarzi; Amir Khajepour] -- The purpose of this book is to cover essential aspects of vehicle suspension systems and provide an easy approach for their analysis and design. The vehicle suspension system is located in the structure-borne transmission path between the road–tyre interaction and the vehicle body, so the design of this system must be done carefully taking into account its behaviour in vibration transmission. This is done via a 2D suspension model on a scale paper or with computer-aided engineering (CAE) . suspension system, which transmits the force between the vehicle and the ground. However, in commercial vehicles like trucks and buses, the . It reduces the vibrational energy of the vehicle body caused by the excitation of the road while keeping the stability of the vehicle within an acceptable limit. 2.1.3. Simulation results confirm that the case of a semi-active MR suspension system incorporating the preview case MPC controller can offer significant prosperity for both ride comfort and vehicle stability compared with other proposed cases of vibration control. Ease for the driver at 1) It must have Shock Absorbers. Those were the golden days for a mechanical engineer. Using results published by the IMechE for the best cars in the competition, the estimated acceleration, braking and cornering loads were applied to 28 design iterations. In addition, vehicle vibration is reviewed in detail and models are developed to study vehicle ride comfort. Using OPTIMUM KINEMATICS the analysis of the suspension system is done. And to be precise, it works as well as the current suspension system such as the wishbone suspension system and trailing link suspension system. Active Suspension System : An active suspension system acquire the ability to reduce acceleration of sprung mass continuously as well as to minimize suspension deflection, which results in progression of tire grip with the road surface, thus, brake, grip control and vehicle maneuverability can be Considerably improved.
