Abstract
The objective of the study was to achieve the better ride comfort for the passengers in the conventional vehicle, by limiting the speed while crossing the sinusoidal bump. For this study, quarter car model with 2-DoF and multi-body dynamics with 4-DoF is considered. Multibody dynamics was generated using the lumped mass parameter. The governing equation of the system was developed by using Newton’s second law of motion. Developed a sinusoidal single bump road profile based on the parameters. MATLAB/SIMULINK software was used to incorporate the system. Simulation test was carried out by varying the vehicle speed and suspension damping coefficient. In this paper head acceleration of the passenger and tire deflection is considered for to quantify the ride comfort and road holding property of the vehicle. The results were carried out for men and women by varying the vehicle speed and suspension damping coefficient. Finally, suitable speed and damping coefficient to achieve better ride comfort for male, female and good road holding characteristic while crossing the sinusoidal bump were mentioned.
