INVESTIGATION OF DYNAMIC RESPONSE OF A SINGLE LAP ADHESIVE BONDED JOINT

Mechanical Engineering, Vibration

The aim of this paper is to study the modal analysis to analyze the dynamic behavior of single lap adhesive joint subjected to impact or shock loads using Finite Element Analysis (FEA) and experimental analysis. In this paper modal analysis of bonded beams with a single lap adhesive joint is investigated. The various factors that affect the response of adhesive joint structures are studied, such as natural frequencies, mode shapes, damping ratio etc.. The finite element analysis software ANSYS 13.0 is used for modal analysis of a specimen. The material used for the specimen is aluminum and adhesive used for lap joint is araldite epoxy adhesive. The initial case study is focused on software modal analysis of cantilever beam subjected to impact load. The main objective of this paper is to determine the natural frequency and mode shape of a single lap adhesive joint at cantilever beam condition and to compare the results obtained by finite element analysis with experimental results and to find the error between them. NI Lab-View 13.0 software is used for experimental modal analysis along with data acquisition hardware. The results obtained by both the methods are found to be satisfactory.
