Abstract

The title of this project is “ UTeM FV Malaysia racing car suspension optimization using geometrical optimization ”. A suspension system for UTeM FV Malaysia racing car will be model by MotionView software using multibody dynamic method. In the vehicle suspension design the optimal suspension should fulfil the following basic requirements: the ride comfort, reduction of dynamic road-tyre forces, and reduction of relative motions between the vehicle bodies. In this project, push rod double wishbone suspension system is used and then analyse the suspension system using kinematic and compliance method. This analysis is done to study the movement of each components in UTeM FV Malaysia racing car suspension and optimize the suspension geometry (kinematic) and shock absorber characteristic (compliance) using geometrical optimization. MotionView analyze data for vehicle dynamics of resulting design and provide the information about the comparison of analyzing data for vehicle dynamics and suspension performance. The optimization method helps to find the optimum locations of the hard points efficiently. For each iteration in the process of optimization, prediction uncertainty is considered and the multi objective optimization method is applied to optimize all the performance indexes simultaneously. It is shown that the proposed optimization method is effective while being applied in the kinematic performance optimization of a push rod double wishbone suspension system. Several optimization techniques were made to optimize the parameters .The study will cover on both front and rear suspension system. As known Suspension system give our car stability, steering control and improve comfort. The suspension allows the wheels to move up and down independently from the rest of the car. That will keep the wheels on the road when hit bumps.
