Design and Analysis of Slotted Block Horn Used For Ultrasonic Power Applications

Abstract

This research aims to contribute a study of design and simulate the ultrasonic block horn configuration containing two slots in order to satisfy these criteria. The simulation and vibration mode shape characterization for the selected horn profiles are discussed and the analysis is accomplished using ABAQUS commercial software package, whilst the vibration modes are classified using experimental data from 3D Laser Doppler Vibrometer measurements. Modal and harmonic analysis are completed successfully to examine the natural frequency for the tuned horn. It is shown in the block horn design that an optimization of slot position will lead to high enough value of longitudinal mode with large uniformity displacement amplitude and low stress across the face of the horn; this is required in many applications and processes to ensure an adequate power transmit to the working parts sufficiently and effectively.
