STUDY OF THE DYNAMICS OF TRUCK MOVEMENT ACROSS A BRIDGE CROSSING

This paper is the first comprehensive study of the dynamics of truck movement across a bridge crossing with defects on a road surface. A mathematical model of the dynamics of the truck movement across the bridge crossing is obtained. To confirm the adequacy of the proposed mathematical model, a comparative analysis of the results of theoretical and experimental studies was carried out. This approach makes it possible to determine the nature of the distribution of dynamic loads in areas where truck wheels contact with the road surface of the bridge crossing. This research was carried out within the framework of the project “Development of a load model based on the actual parameters of heavy rolling stock to determine the carrying capacity of road bridges during their restoration and operation in the war and post-war periods” under the competition “Science for the Reconstruction of Ukraine in the War and Post-War Periods” at the expense of grant support from the National Research Foundation of Ukraine.
