Modal Analysis of Horns Used in Rotary Ultrasonic Machining

Praveen Kumar Rai and Rabindra Kumar Patel


The horn is an important element in transferring the ultrasonic vibrations received at its input end from the transducer to the end of the horn in ultrasonic machine. So, the design of the horn has a huge impact on the amplitude of ultrasonic vibrations being imparted to the end of the horn. The most important aspect of the horn design is the determination of the resonant frequency, the resonant length, and the magnification factor of the horn. Hence, different sonotrode shapes have been studied and analysis is performed to identify the desired shape of the concentrator. Modal analysis was performed to calculate the mode shapes, natural frequencies, as well as the resonant length of different shapes of the horns. Here the modal analysis is performed for the horn used in rotary ultrasonic machining. Therefore, the required analysis is performed using ANSYS 15.0 workbench interface and the dimensions of the sonotrode resonant frequency within the range of 15 – 30 kHz is selected
