Item Modelling, Simulation and Experimental Validation of Half Semi-Truck Suspension System Vibration(Published Faculty of engineering, University of Ilorin, 2025) Olalekan Tajudeen POPOOLA; Ibrahim, Hassan Kobe; Akinola, E.A.; Osatuyi, F.W.; Tijani, Z.O.; Abdulazeez, K.O; Mustapha, F.O; Kelani, T.M.This paper is aimed at modelling and experimental validation of the vibration models of a semi-truck suspension system. A half-car (4-degree-of-freedom) model was developed for the semi-truck vehicle using the Newton law and simulated using SCILAB-Xcos. The analysis specifically focused on the acceleration response of the vehicle body at different speed levels (10, 20, and 30 km/hr), which was determined with the smartphone-installed accelerometer (Keuwl app). The simulated root mean square accelerations of 0.33, 0.55 and 0.72 m/s2 revealed a favourable comparison with the experimental root mean square accelerations (0.31, 0.54 and 0.69 m/s2) at 10, 20 and 30 km/hr, respectively. This showed that the ride comfort is not an uncomfortable zone at low speeds, and many are considered fairly uncomfortable. The findings provided valuable insights into the dynamic behaviour of semi-truck vehicles, highlighting the role of speed in suspension system performance. This information can be utilised to optimise vehicle performance, enhance ride comfort, and improve overall safety.
