Abstract: 

The handling quality of a passenger car is noticeably influenced by the structural and functional characteristics of the individual components of the vehicles various mechanisms, including the steering, suspension and braking systems. This implies that in designing each of these mechanisms, its contribution to the dynamic behavior of the vehicle should be taken into account. In this paper the sensitivity of the vehicles handling quality to the geometry of a rack-and-pinion steering mechanism, specially to the coordinates of its joints, is analytically studied and a new Genetic-based approach the determination of the joint coordinates is proposed. In the proposed approach, the dynamic equations and kinematics constraints of the steering mechanism are derived and incorporated in a dynamic model of the vehicle. The model is then solved for a step-input to the steering wheel, using MATLAB, and the values of the handling parameters are calculated. An Elitist Genetic Algorithm is used to search the hyper-space of the joint coordinates and to find the ones resulting in the best handling quality. The advantages of the proposed method over the classical solution methods are also discussed.
