Development of locomotive skid prevention devices based on object modeling of technical solutions

Techniques of prevention of locomotive wheelsets skidding were analyzed. The relevance of using object modeling techniques to automate the design of devices to prevent skidding is shown. The main task the solution of which is devoted to the article is the synthesis of the object model of technical solutions of such devices, the calculation and compilation of matrices of measures for inclusion, intersection and similarity. As a result of object modeling, the closest technical solution (prototype) was chosen, its characteristic features and disadvantages were identified. Novelty of results obtained in the present article consists in proposed device for prevention of skidding, application of which makes it possible to reduce power losses caused by eddy currents created by magnetic field in wheels and rail, to reduce energy consumption for creation of magnetic field, due to the fact that magnetic field is created only at possibility of wheels skidding and current values are maintained at minimum required level. The methodology and results of the scientific investigation can be used in the synthesis of new technical solutions aimed at improving the components of the crew of locomotives
