The article addresses the issue of time delays that occur in dynamic vibration measurements of rail vehicles in accordance with the UIC standard. This problem arises from the standard’s definition of the operator transmittance of a band-pass filter, which limits the vibration frequencies under investigation and does not account for high-speed measurements. The assumptions of the UIC 518 standard are presented, along with the causes of measurement errors, with particular emphasis on errors caused by the defined filter.One of the types of tests conducted to confirm the safety of vehicle operation and vibration parameters determining their suitability for specific transport applications are vibration tests of rail vehicles.
