【摘要】 以松花江河冰为研究对象，从河冰细观结构研究入手，结合超声辅助切削验证实验，对超声辅助切割冰块的效果以及提高生产效率的可行性进行分析。仿真结果表明，对于晶体复杂的天然河冰，超声辅助切削能减小约38%的切削力。验证实验表明，超声辅助切削在提高进给速度的同时能保证冰体切削质量，不易发生崩边和裂纹，相较于传统切削，对河冰生产质量和效率的提高效果显著，超声辅助切削用于大规模制备标准冰块是可行的。更多还原

【Abstract】 Taking the Songhua River ices as the research objects, starting with the study of the mesostructure 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.更多还原
