The Transformation of Vibrations of the High-Tension Pillars by Homogenization in the Vibrations of the Finite String
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 1
Abstract
In this article we study the waves equation on an high-tension pillars with alveolar form. Geometric, high-tension pillars are represented by a thin, tall structure where the edge base is denoted by e, the thickness of the material - distributed along the layers is denoted by and the alveoli is distributed with the period . The parameters e, ε, δ are considered small, e « ε. This article consists in passing to the limit after e → 0, ε → 0, δ → 0 in this order, in the problem of the free vibration, the result is a mixed problem for the one-dimensional wave equation, in which the homogenized coefficient that appears is a combination between the constants that characterized the material. The result of our paper is identically with the result from [3].
