Study of Road Variability and Its Effects on Vehicle Dynamics Simulation

As the technology is burgeoning with the passage of time the numbers of methods have been developed in the field of automobiles. Vehicle dynamics and ride comfort is the major part which is to be considered a lot these days. These are improved to comfort the passenger and the driver of the vehicle. Less vibration will result in more ride comfort and hence less discomfort for the driver. Hence this is more necessary for the health of the driver and the passenger. In this paper, the study was done regarding the vehicle dynamics with different road profiles. Dynamics of the vehicle was considered experimentally and there results were simulated in MATLAB/SIMULINK software. The half car model and there equations are investigated in the MATLAB/SIMULINK software to determine the vibration in the investigated vehicle. Also investigation regarding the ride comfort and road holding had been considered by using different formulas and then this ride comfort was optimized using the DOE software. The optimized result gives the combination of the stiffness and damping coefficient which was then used for the better ride comfort. This combination was again put in the form of parameters in the MATLAB/SIMULINK model to get the optimal and best solution.
