Ultrasonic Assisted Cutting Simulation and Validation Experimental Research Based on River Ice Mesostructure

Taking the Songhua River ices as the research objects, starting with the study of the meso⁃structure of river ices and combined with ultrasonic assisted cutting validation experiments, the effectiveness of ultrasonic-assisted ice cutting and the feasibility of improving production efficiency were analyzed. The simulation results indicate that ultrasonic assisted cutting may reduce the cutting force by approximately 38% when applied to the complex crystalline structure of natural river ices. Validation experiments demonstrates that this method enhances the feed rate and maintains the cutting quality of the ices, effectively preventing edge collapse and crack formation. In comparison to traditional cutting techniques, there is a significant improvement in both production quality and efficiency for river ices, thereby confirming the feasibility of employing ultrasonic assisted cutting for large-scale preparation of standard ice blocks.
