Vibration Response of Tubular Joints Using a Simplified Mass-Spring Model

Abstract

Using adhesives for joining tubular structures has been widely used to replace the traditional joining methods of welding, brazing, soldering, etc. The unique features associated with adhesives include low manufacturing cost, long components’ life, and lightweight. The goal of this study is to investigate the vibration response of the tubular joints when they are subjected to a harmonic axial load considering that the shear stress is linear through the thickness. A simplified mass-spring model is applied to study the response of the problem analytically. Finite element method (FEM) using ANSYS is then availed to validate and compare results obtained in the analytical approach. Additionally, some parameters such as overlap length and adherent material will be changed to examine their influence on the frequency response. Results and findings achieved analytically and numerically showed that the natural frequencies increase as the adherent wave velocity increases, whereas they decrease as the overlap length increases.
