Research on simulation analysis method of RAIKO P15 ice-roller tool vibration crushing compacted ice-snow

The ground-excited ice-roller has been able to effectively solve the problem of ice-snow on the roads, but its ice breaking mechanism, operating parameters and efficiency still need to be studied and improved. This paper, taking effect of RAIKO P15 ground-excited ice-roller tool vibration crushing ice-snow as the research content, established a finite element model of tool and compacted ice-snow by using ANSYS/LS-DYNA, realized the simulation analysis of the process of ice-roller tool crushing compacted ice-snow, obtained the crushing effect of 10mm thick compacted ice-snow and the stress distribution of tool under different vibration frequencies, and determined that the optimized vibration frequency of ice-roller is 25 kHz. The simulation method and analysis result in this paper provide the method and basis for the design and manufacture of ice-snow removal equipment tool.
