Experimental Vibration Analysis and Modal Analysis of Sheet Metal Structure Reinforced With Elastic Material

Gokul V. Mahajan

Abstract :

Sheet metal structures are subjected to various static and dynamic loads during their operation due to this they encounter resonant condition at various operating frequencies. Resonance leads to harmonic excitation which induces deformation and stress loading which leads to fatigue failure. Reinforcement of sheet metal structure with elastic material such as rubber, foam helps in achieving structural stiffness. Stiffness alteration loads to change in dynamic characteristics, natural frequencies, harmonic resonance etc. Modal and Harmonic analysis will be simulated using FEA analysis (ansys workbench). Impact hammer and FFT analyzer will be used for validating natural frequencies for structure with and without reinforcement. Result and conclusion will be drawn. Suitable future scope will be suggested
