Determination of the vehicle's carrying capacity taking into account the bearing capacity of the roads

Abstract

Increasing the efficiency of using the technical parameters of trucks, in order to save resources, remains an urgent task in the operation of vehicles. Maximum vehicle performance is achieved when the vehicle's rated payload capacity is used to its full potential. As practice shows, due to the regulation of weight parameters, the actual carrying capacity, and, consequently, the performance of the vehicle is reduced. The increased load leads to the destruction of the road surface, therefore, for exceeding the standard values of the weight parameters of the car, carriers are subject to administrative punishment in the form of a fine. The actual task is to determine the actual load capacity of the vehicle when the limit value of the axle load according to the regulatory document is ensured. This paper proposes a method for determining the carrying capacity of road trains consisting of a truck tractor and a semi-trailer, taking into account the bearing capacity of highways. When determining the actual mass of the transported cargo, the maximum permissible values of the total mass and axle load of the vehicle were taken into account, which depend on the category of the road, as well as on the design features of the vehicle (type of suspension, wheels, center distance).
