Abstract
The lack of the necessary amount of equipment for winter maintenance, significant precipitation leads to a decrease in the efficiency of roads. Inside, courtyards and sidewalks are also covered with a layer of compacted snow due to untimely snow removal. The mechanical method of breaking compacted snow is currently insufficiently studied and so far there is no effective equipment to combat snow and ice formations. A peculiarity of the process of compacted snow destruction in the mode of “vibration cutting” is intermittent contact of the blade with the destroyed medium. Condition of steady mode of vibration cutting is criterion of vibration scraper blade release from contact with medium to be destroyed. The purpose of the study is to establish the time at which the contact of the blade with compacted snow is interrupted. Obtained results of calculations make it possible to set values at which vibration cutting mode is possible and to select parameters of hydraulic accumulator, which provides movement of the vibrocleaver blade of compacted snow.
