Abstract:
An analytical model for the performance of two-stage rotary snowplows is developed to consider both high-velocity operations and the effect of snow properties on machine performance. The analysis determines the power required to cut and disaggregate the snow, the snow removal rate, and the total power required by the system. The purpose of the model is to perform parametric assessments of the rotary snowplow's performance and efficiency. The model results show that the strength of the snow has considerable effect on the power required by the auger to disaggregate the snow and on the total power required for removing the snow. Unfortunately, the available data from field tests of full-scale rotary snowplows are limited and no quantitative verification of the model can be made; however, the model does allow qualitative assessment of the effects of changing the rotary snowplow configuration or the properties of the snow.
