The author described the methods for statistical processing of experimental information of various considered techniques for measuring lateral forces, which enabled to justify the choice of the reference measurement technique.

Based on a set of known experimental techniques, the author proposed to take statistical estimates of the measurement error established by the current interstate regulations as criteria for the validity of the choice of a reference measurement technique.

Determination of the reference measurement technique involves conducting purposeful experiments with similar conditions, including the types of rolling stock under test, the parameters of the device and structure of the permanent way of the measured section, meteorological parameters, etc. The author has applied the procedures that include the choice and justification of the reference value of the measured indicator, comparison of statistical estimates of the measurement error of lateral forces along with the requirements imposed on the conditions for conducting experiments in accordance with the requirements of regulatory documents of Rosstandart.

The presented method for determining the reference method for measuring the lateral forces of the impact of the wheel on the rail head according to the deformations of the rail considers the requirements of the regulatory documents of Rosstandart and can be used in the experimental evaluation of interaction indicators in the mechanical wheel — rail system.
