| Abstract | ||
| This study investigates the enhancement of vehicle ride comfort through the implementation of a tuned mass damper (TMD) system, specifically in a 2-degree-of-freedom (DOF) quarter-car model. The research evaluates the TMD’s effectiveness in mitigating vehicle vibrations induced by two distinct road input types: random road input, simulating unpredictable surface irregularities, and sinusoidal road input, representing periodic road undulations, and focuses on optimizing TMD parameters to attenuate vibrations and improve passenger comfort according to vehicle dynamics criteria (Body acceleration, Suspension working space (SWS), and Dynamic tire load (DTL)). A comprehensive mathematical model of vehicle dynamics, incorporating the TMD, is developed and simulated by using MATLAB/Simulink program. The novelty in the research is to examine and discuss the impact of spring stiffness values on the TMD’s spring stiffness and its subsequent influence on the performance of the quarter-car model. The simulations analyze the system's performance in reducing vibration amplitudes and improving ride comfort indices compared to conventional suspension systems. Results indicate significant potential for the TMD system to enhance ride comfort across different vehicle speeds and road profiles. This study provides insights into the effectiveness of TMD systems in vehicle dynamics and contributes to the development of advanced suspension technologies aimed at optimizing passenger comfort. | ||
