Abstract


Authors develop the high speed snow compressor (HSSC) to assist the snow disposal at aging and depopulation marginal society by reducing the disposal volume. The snow consolidation density by using square cross section pressure vessel and mechanical press machine was investigated for obtaining newly fundamental data. And a back pressure on inner lateral wall of the pressure vessel was investigated to confirm an occurrence of ununiform deformation of the snow or not. Some tests for different geometry conditions of H/W = 0.5, 1.1 and 1.7 were performed to investigate the geometry effects on the snow consolidation properties, respectively. Here parameter H and W show height and width of the pressure vessel, respectively. By the result, it was found that the snow was easy consolidated by lower axial formation pressure compared with cases by using hydraulic press machine. And the snow consolidation properties by using mechanical press machine were almost same for H/W = 0.5, 1.1 and 1.7. And occurrence of large impulsive force at bottom dead center was observed, but the excessive large force is not related to increase the snow compaction density was found quantitatively.
