Comparative analysis of Russian and foreign regulatory requirements for vibration protection of a tractor operator

The paper discusses the main requirements of Russian and foreign regulatory documents on vibration protection of the operator's workplace of wheeled and tracked vehicles. Their comparative analysis was performed. The normalization of the parameters of general vibration at the workplaces of operators of tractors and self-propelled agricultural vehicles in our country occurs in accordance with the requirements of SN 2.2.4 / 2.1.8.566-96, GOST 12.1.012-2004 and GOST 12.2.019-2015. The root-mean-square values of vibration accelerations for a certain period of exposure in each octave (one-third octave) frequency band are allocated as the evaluation criteria. They are compared for compliance with the regulated values from a specific standard. At the international level, the object of compliance is the ISO 2631-1: 1997 standard, which establishes the requirements for vertical and horizontal vibration with a certain exposure time on a person from 1 minute to 24 hours in the frequency range from 1 to 80 Hz. The article shows that the most stringent requirements for the level of local vibration are established in the Russian Federation. They provide clear regulation of the type of work performed, duration, magnitude, direction of existing loads, etc. Relatively soft requirements are in most European countries, except Poland, where the MPL is regulated taking into account the age, gender and condition of a person. In addition, in the regulatory documents of most foreign countries there are two and sometimes three indicators: threshold (upper and lower) values and MPL. When the threshold is reached, primary measures are usually initiated to counter harmful factors.
