Analysis of Ultrasonic Horn with Finite Element Method

Abstract

In this study, the mode shapes and natural frequencies of the horns with different geometries are to reveal an important aspect of the design by using FEM based ANSYS software. Modal analysis of flat horn, conical horn, Bezier type horn and sonotrode type horn profile for four different horn materials was performed using finite element based ANSYS software. Plain carbon steel, stainless steel, aluminum and titanium were selected as horn material in the analysis. It has been observed that different frequencies are observed in different mode shapes and our desired frequencies are the mode in which we have a resonance longitudinal vibration mode. For industrial application, it can find suitable material selection for ultrasonic machine in a certain frequency range. When the obtained results are examined, one can select the appropriate material, suitable size and suitable shape for a particular industrial ultrasonic machine application.

Ultrasonik Makinede Boynuzların Sonlu Elemanlar İle Analizi

Abstract

Bu çalışma ile farklı geometrilere sahip boynuzların mod şekilleri ve doğal frekansları FEM tabanlı ANSYS yazılımı kullanılarak analiz edilmiştir. Dört farklı boynuz malzemesi için düz boynuz, konik boynuz, bezier tipi boynuz ve sonotrot tipi boynuz profilinin modal analizi, sonlu eleman tabanlı ANSYS yazılımı kullanılarak gerçekleştirilmiştir. Analizlerde boynuz malzemesi olarak sade karbonlu çelik, paslanmaz çelik, alüminyum ve titanyum seçilmiştir. Farklı mod şekillerinde farklı frekansların gözlemlendiği ve istenen frekanslarımızın rezonans boylamsal titreşim moduna sahip olduğumuz mod olduğu gözlemlenmiştir. Analizle elde edilen frekans aralığı gibi bulgular endüstriyel uygulamada ultrasonik makine için en uygun malzeme, boyut ve şeklin seçimine katkı sağladığı elde edilen sonuçlarla doğrulanmıştır.
