Experimental Analysis on Fracture Characteristics and Material Properties of Compacted Ice and Snow

Abstract:

It is benefit to improve the snow clearing effect, reduce energy consumption, conserve resources and enhance the performance of the machine was pointed. Using the depth into show, concave disc spacing and the angle between marching directions as factors, snow pack volume flaking, fracture width and snow clearing resistance as objective the three factors five levels orthogonal rotation test was conducted. The interaction between effect spacing of tools ,the fractures great influence on clearing efficiency and energy consumption when clearing the compacted ice and snow by using multi-blade cutting mode was found through the concave disc cutting test. The relation response surface graph was obtained through the analysis of test data by using the Design-Expert 6.0 software. The optimal parameters are: the angle between marching directions is 13°, depth into snow is 38mm~44mm, concave disc spacing is 14mm~17mm, which made the snow pack volume flaking is 124cm3~130cm3, the fracture width is 79mm~80mm, the snow clearing resistance is 0.6KN~0.65KN.
