Strength research working equipment of rotary snow blower

Abstract

The article presents the results of theoretical studies aimed at studying the issue of increasing the efficiency of a rotary snowplow. A list of possible indicators used as performance criteria is presented, characterizing both individual subsystems and a separate system as a whole, in the field of road, construction and municipal vehicles. As a criterion for the efficiency of the working equipment of a rotary snowplow, from the presented list, in this case, the power expended on transporting the snow mass was selected. Graphical dependences are presented that reflect the values of the forces of normal reaction of the side surface of the cutter of the feeder and graphical dependences of the maximum value of the normal reaction force of the supporting surface of the feeder on the size of the transported particles. Cartograms of the average values of the forces of normal reactions of the supporting surface and the side surface for particles with a characteristic size of 0.03 m are shown, built on the basis of the results of spatial averaging of the calculation results. The influence of the characteristic dimensions of transported particles on the performance indicators of the working equipment of a rotary snowplow is considered. The regularities established as a result of a comparative analysis of the averaged values over space and the average total values over time for both the supporting and side surfaces of the working equipment of a rotary snowplow are presented.
