Abstract

Dynamic load is one of the factors that have a significant impact on the stability and durability of car components. In addition, dynamic loads also affect the destruction of traffic infrastructure. In this paper, the survey results are presented on the influence of the speed of movement on the dynamic load of the three-axles vehicles. The simulation process is hypothesized when the vehicle is moving at a speed v (km/h) =[30;40;...;80;90] and when passing through the pavement contours with random elevations. different according to ISO 8608:2016. The purpose of this study is to build a dynamic model of three-axle vehicles to investigate the dynamic load acting on the vehicle. Application of Matlab-Simulink software to simulate dynamic loads generated by excitation from random pavement bumps with different speed ranges.
