Method of obtaining and using the distribution of the second derivative of the current strength of the traction generator of a shunting locomotive

On the basis of a previously proposed General method of using a database of measurements onboard system parameters diesel generator set of shunting locomotives a technique of determining the distribution law of the values characterizing the intensity of change of current of the traction generator, evaluation parameters, determining a model function of the parameter changes on the overhaul period. The technique and criteria for assessing the technical condition of the diesel generator set of the observed locomotive using the model function are given
