The paper suggests application of an experimental method for the assessment of the dynamic effect of a locomotive underframe on the railway track.The assessment is to be based on the spectral analysis of the response of structural elements of the railway track undergoing a shock pulse.Application of digital measuring systems for monitoring of motion of the train is also proposed.Shock absorbers are intended for developing forces providing the elimination or reduction of the amplitude of cars or their parts fluctuations.On the CIS railroads, the wedge-type shock absorber became the most wide-spread in trucks of freight cars.In friction shock absorbers, the friction force arises in vertical and horizontal movements of the absorber wedges rubbing on friction plates fixed on the columns of the truck sidewalls.Given the above, to increase the level of safety of railway operation, it is necessary to apply progressive methods of diagnostics and monitoring aimed at the assessment of the vibration level occurring during operation and of the current status of all elements of the railway track.The need and urgency of implementing innovative systems and means of diagnostics and monitoring of the railway facility are reflected in programs for the development of railway system until 2020 in the Republic of Kazakhstan.
