The lack of the necessary amount of equipment for winter maintenance, significant precipitation in the form of snow, lead 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. Mekhanic 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 knife with the destroyed medium. Condition of the set mode of vibrocutting is the criterion of an exit of a blade of a vibrocleaver from contact with the destroyed environment. The aim of the study is to establish the time at which the knife comes into contact with compacted snow. The obtained results of the calculations make it possible to set the values at which the mode of «vibration cutting» is set and to select parameters of the hydraulic accumulator, which ensures the movement of the blade of the vibrocleaver of the compacted snow.
