In ultrasonic machining (USM), higher amplitude is required for higher material removal rate (MRR). The objective of this research is to develop a new horn design for high displacement amplitude for getting maximum MRR within a working condition. The profile of the horn has been optimized and designed. In this analysis, optimization procedure and finite-element method have been used for the design of horn of USM. In this, the variation of stress components along the length of the horn has been studied. In the middle, maximum stress is found due to a change in cross-section but it is within the endurance limit of the horn material. The cubic Bezier horn as compared with traditional horn is up to 19% more amplified. Finally, an optimized cubic Bezier profile for the horn has been designed, which has maximum displacement amplitude for higher MRR and safe working stresses for the horn material.

超声加工立方贝塞尔角的设计优化

在超声加工(USM)中,需要更高的振幅才能获得更高的材料去除率(MRR)。这项研究的目的是开发一种用于高位移幅度的新型喇叭设计,以在工作条件下获得最大的MRR。喇叭的轮廓已经过优化和设计。在此分析中,优化程序和有限元方法已用于USM喇叭的设计。在这种情况下,已研究了应力成分沿焊头长度的变化。在中间,由于横截面的变化而发现最大应力,但它在喇叭材料的承受极限之内。与传统的号角相比,立方贝塞尔曲线号角放大了多达19%。最后,针对号角设计了优化的三次贝塞尔曲线轮廓,
