摘　　要：根据二氧化硅气凝胶材料特点,设计并研制了一种新型二氧化硅气凝胶材料超声车削声学系统。采用四端网络法对声学系统的变幅杆及加工工具进行理论尺寸计算,并通过有限元法对整个声学系统进行模态分析。研究了二氧化硅气凝胶材料车削时在无超声辅助及施加超声条件下的切削力大小,对比实验结果证明,经过超声车削的二氧化硅气凝胶材料具有切削力小、加工表面质量好等优势。In accordance with the characteristic of silica aerogel, a new acoustics system of the ultrasonic cutting on the aerogel materials was developed. The amplitude amplifier pole and tool have been designed by four-terminal network, and acoustic system was optimized through the finite element analysis. Research on the cutting force of aerogel materials turning without ultrasound assisted and under ultrasonic condition, and the contrastive experimental results show that the ultrasonic turning the aerogel materials have an advantage of lower force and surface quality.
