Abstract

A common situation on the railways is that numerous vehicle data are experimentally defined. But for numerical and computational calculations it is necessary to present this data in functional forms. This paper defines methods for the determination of basic traction characteristics of railway traction vehicles: basic resistance and tractive effort produced on the wheel tread, provided we have experimental data. The well-known method of least squares is used for determining coefficients of function and correlation coefficients which best represent experimental measurements and are applied to experimental data. All calculations are conducted on the basis of the data received during test runs of
