Dynamic method of control of weight of cargo transported by vehicle

Abstract

The existing methods of control of the total weight of vehicle are based mainly on strain measurement methods and are implemented in the form of mobile or stationary weighing platforms. The main drawback of such systems is the need to enter the vehicle on the weighing platform. In the context of a developed road network, this approach does not allow to track the weight of all vehicles moving on roads, and thus creates conditions for incomplete identification of vehicle, the total weight of which exceeds the permitted for a particular road. Existing strain gauge weighing systems, placed directly on the vehicle, tend to deteriorate the accuracy of weighing for a certain time of operation. The several works performed in the 90s of the twentieth century describes the method of dynamic control of the weight of vehicle and train. However, the method does not contain a clear theoretical scientific justification and is based on experimental data, so this method has not been further developed. The article presents a theoretical justification of the dynamic method of controlling the weight of vehicle, implemented on the basis of the analysis of the dynamics of angular accelerations of the motor of a vehicle during acceleration on identical surfaces in the empty and loaded state.
