Negative effects of the oscillatory motions of vehicles upon the ride comfort and controllability are reduced by optimizing the characteristics of the elasto-damping elements in the vehicle. The optimization reported in this work has been carried out by using a nonlinear vehicle model, nonlinear characteristics of the elasto-damping elements, and modified Nelder-Mead method. The modifications were made in order to enable the problem of optimization of the characteristics of elasto-damping elements to be solved in the presence of constraints on the values of the optimizing parameters of the vehicle (within the appropriate defining ranges)
The objective function adopted in this work provided for simultaneous minimization of vertical oscillations, of the roll and pitch motions of the suspended mass, of the vertical oscillations of the wheels, and of the normal dynamic road reactions. Possibilities for application of the developed optimization method are illustrated by means of a case study involving a middle class passenger car.
