Abstract

The structural design and manufacture of the horn will directly affect the performance of the horn. Although many scholars have carried out research and Analysis on the horn, but there has been a long blank research on the long horn. Super long horn is mainly used for machining deep hole parts. It plays an important role in ultrasonic vibration aided machining system. In this paper, a longitudinal wave horn with 1/2 wavelengths is taken as an example. The design and calculation of conical transition composite horn and exponential transition composite horn are carried out by using the four terminal network method. The design results are analyzed by finite element simulation. Some problems in the design and application of the two kinds of horn are pointed out.
