Features of normalization and evaluation of vibration from rail transport in premises of residential and public buildings
The analysis of the normative and technical documentation establishing the requirements for the regulation of non-constant vibration is given. The existing contradictions are noted and recommendations for their elimination are offered. It is shown that in accordance with the current sanitary regulations, the equivalent value of the frequency corrected vibration velocity or vibration acceleration or their levels should be taken as the standardized parameter of the rail transport vibration. For workplaces acceleration is used as this parameter The arguments are presented in favor of the adoption of the corresponding values of vibration velocity as a standard parameter in the premises of residential and public buildings. It is shown that it is necessary to include in the composition of the parameters to be regulated the maximum value of these quantities and the expediency of simultaneous evaluation of both values. The corresponding normative values are given. The limiting values of the normalized parameters in octave bands of the frequency range typical for the rail transport are given, which can be used to select the means of vibration protection.
