Application of gravitational method by determination of rail vehicles constant resistance

Abstract

Methods for the determination of rail vehicle motion resistance are briefly described, with special consideration given to the gravitational method of movement down an incline. After a theoretical discussion, an example of the application of the gravitational motion method by sqaled-down model of a T 155 - EAM'SD 35 rail vehicle in HO standard 1:87 is presented in idetail. Experimental imaging is accomplished by means of a digital camera. Temporal measurements are obtained by snapshot reading. Rail vehicle constant resistance in relation to velocity is determined by the gravitational method. The application of this method on a scaled-down model is proved and it can be easily used on real models.
