“…They used mild steel, titanium, stainless steel, and aluminum as a material for their horns and found a horn made of titanium material that shows higher amplification and can be utilized in UW without failure due to dynamic loads. The performance of the stepped horn to be used in ultrasonic-assisted welding was analyzed by wang et al [14]. Raj et al [15] used FEM for designing and optimization of quadratic and cubic Bezier ultrasonic horns for rotary ultrasonic machining system.…”

The composite materials Si/AlC, crystal quartz, and ceramic glass are becoming an important part of the present society in many engineering and non-engineering fields. Conventional methods available for machining these materials have many flaws due to which their application on large scale is restricted. A non-conventional process known as ultrasonic machining (USM), can be implemented for machining of these materials effectively. Anyhow machining efficiency of USM greatly depends upon its horn design and therefore in the present study a horn based on a catenoidal profile with aluminum and titanium material for USM was designed and developed by using solid works and ANSYS. Modal and harmonic analysis was done on the horn for computation of various parameters of interest such as resonant frequency, amplitude vibration and equivalent stresses. After the computation of the results, they were analyzed and compared with those available in the literature in terms of stresses and magnification factor for their validation comparison with literature, it was found that an aluminum catenoidal horn shows higher magnification with the least stress magnitude as compared to horns avail-able in the literature and hence can be used in USM as a replacement for existing horns.

“…In this figure, the value of the axial stress increases with the increase in the frequency and the variation of stresses over the horn also increases, but the value of stress is much lower at the resonance frequency (23.6 kHz) as compared to other frequencies. Figures 18,19, and 20 show the variation of the components of the circumferential, radial, and shear stresses and the axis of horn for the various frequencies. Also in Figs.…”

“…Then, the numerical modal analysis of an ultrasonic-assisted surface rolling has been performed both assembled and individually in a complete ultrasonic-assisted surface rolling system. Wang et al [19] have suggested that from the ultrasonic radiator configuration point of view a new design method is present in this study, which applies a stepped-plate to the horn end. For designing a stepped-plate radiator, the combination of mapping the acoustic field with arc-acoustic interaction using welding experimental measurements provides directive evidence.…”

Rotary ultrasonic machine (RUSM) has a lot of applications in industries, with the recent uses of stronger and harder materials. Machining performance of RUSM depends on the design of the horn. A horn also known as a tool holder or concentrator is a waveguide focusing device, which has a decreasing area of the cross section from the upper to lower end. In RUSM, the high amplification factor of the horn is required to increase tooltip vibration for getting a high material removal rate. In this study, the design of the horn using an optimization procedure and finite element analysis (FEA) has been done. FEA-based MATLAB code has been developed for finding all the stress components, axial amplitude, and resonance frequency. Results are validated from the experimental data available in the literature, and it has been found that it is in good agreement with the literature. The amplifications of the horns with cubic and quadratic profiles 23.8% and 19%, respectively, are higher than the traditional horn with the same length and diameters of the ends. Stresses at different locations have been found within the allowable endurance limit. The effect of frequency on the stress distribution has also been studied and found that the variation of stresses over the domain of horn increases with an increase in frequency, but the value of stress is much lower at the resonance frequency.
