Vibration control of a vehicle using region reduction division criteria

In this paper, we propose a new hybrid method based on region reduction division criteria (RRDC) and advanced real coded genetic algorithm (ARCGA) for solving the suspension design problem. The problem is concerned with determining the passive suspension parameters of the vehicle for comfortable ride. The two dimensional model of the vehicle with non-linear suspension springs and linear dampers has been considered and the vibration experienced by the vehicle due to induced excitation has been minimised by the proposed method. The suspension parameters have been found by minimising the bouncing transmissibility of the sprung mass subjected to technological constraints, in time domain. In order to solve the problem, the constrained optimisation problem is first converted into an unconstrained one by penalty function technique. Then to the transformed problem the proposed hybrid method is applied. To verify the validity of the obtained parameters model simulation has been done over the three roads and the re...
