中文摘要：

随着制造业的不断发展，对产品的加工精度要求愈来愈高，然而微小毛刺的去除仍然是十分困难的。毛刺虽小但危害巨大。因此，有效去除毛刺已成为加工中不可或缺的工序。而超声波去毛刺法可以有效快速的去除复杂零件的微小毛刺，具有很高的实用价值。尽管超声波的相关理论日趋完善，但是超声去毛刺机理以及空化产生的高压对毛刺的影响缺乏一些理论参考。此文阐述了超声波去毛刺的基本原理，利用有限元软件ABAQUS对单个空化泡在毛刺上的溃灭过程进行数值仿真，证明了超声波去毛刺的可行性，通过实验验证，超声波能够有效的去除毛刺。其研究结果为进一步研究超声波去毛刺的理论提供了参考。

英文摘要：

With the continuous development of manufacturing industry, the requirement Ior ~Hv pIu~ s precision of the product becomes higher and higher, but some tiny burrs are still very difficult to be deburred. Although the burrs are small, they are very harmful to the parts. Therefore, effective deburring has become an indispensable processing procedure. Ultrasonic deburring can effectively deburr the complicated parts, and therefore it is of great value for practical purposes. Although the theory of ultrasonic deburring has been established, deburring mechanism and the effect of high pressure from the cavitation lacks of theoretical reference. This paper describes the basic principle of ultrasonic deburring, and numerical simulation was carried out on collapse process of single bubble by using ABAQUS software. It demonstrates the feasibility of the ultrasonic deburring, and verifies it through experiment. For the further research of ultrasonic deburring theory, this paper provides a reference.
