FINITE ELEMENT MODELING OF ULTRASONIC ENERGY CONCENTRATORS USED IN MECHANICAL PROCESSING

Constantin RADU, Paulina SPÂNU, Ana Maria BOGATU

Abstract


The paper presents the importance of finite element design and modeling of ultrasonic energy concentrators used in mechanical processing. The use of the finite element method allows costs reducing research and reducing the time required to find the optimal variant of the geometric elements of the concentrator.

The correct choice of the geometric shape of the concentrator allows obtaining an amplitude corresponding to the contact between the surface to be processed and the concentrator. A small amplitude is not enough and an amplitude that is too high can lead to premature damage of the concentrator.

This paper presents a comparison of the different geometric shapes used to create ultrasonic energy concentrators. Finite element modeling helps us to easily identify the nodal planes and the optimal operating frequency of the concentrator.
