Đánh giá ảnh hưởng độ cứng lốp xe đến tải trọng động Xe tải 3 cầu

Abstract

During the movement, dynamic loads generated by these means of transport significantly affect the bridge/road and the dynamic safety of the vehicle. Load effects include structural damage to transport infrastructure and seriously degrade the road and bridge system. In addition, it also affects the safety of vehicle drivers and the durability of vehicle components. One of the load-related factors is tire stiffness. To have a basis for analyzing the influence of tire stiffness on dynamic loads acting on three-axle trucks, the author has built a dynamic model of the vehicle, set up a system of differential equations, and used Matlab software to determine the dynamic load acting on the vehicle when the tire stiffness changes. The evaluation results show that the dynamic load increases proportionally to the tire stiffness, at travel speeds and on roads of poorer quality.
