SIMULATION STUDY OF VIBRATION OF 5-SEAT SEDAN

Abstract

This paper presents the simulation and evaluation process of the vibration of a 5-seat sedan using a seven-degree-of-freedom model, built and simulated using MATLAB/Simulink software. The model focuses on key components of the vehicle's suspension system, analyzing their impact on the vehicle's vibration behavior during motion. Simulations are conducted at various speed ranges to investigate how the vehicle's vibrations change with speed and operating conditions. After the simulations, the obtained results are used to assess the vibration levels of the 5-seat sedan under different driving conditions. Conducting simulations at different speeds provides a detailed and accurate understanding of the vehicle’s response in diverse traffic situations, enhancing the reliability of the research outcomes. The simulation results will then be compared with experimental data collected from realworld tests to verify and adjust the model’s input parameters, providing a solid foundation for future studies on vehicle vibration.
