Title

Effect of the Impact Location on the Frequency Response Function (FRF) in Finite Element Modal Analysis.

Abstract

The most important tool for understanding the vibration characteristics of mechanical structures or component is modal analysis. It converts the vibration signals of excitation and responses measured on a complex structure which are difficult to perceive, into a set of modal parameters. Previously, methods used for studying vibration of plates are essentially based on either theoretical solutions or experimental works. However, due to the inherent difficulties and mathematical complications, to provide approximate solutions, numerical methods along with experimental and analytical methods are widely preferable. The Finite Element Method is a numerical tool to find the field variable in complex situation. Effect of the impact location on the resulting Frequency Response Function (FRF) is discussed in this research work. For this analysis, Aluminum (Al 6061T6) is used as the parent material and Butyl Rubber is used as Viscoelastic Damping Material (VDM) for preparing the composite material specimen. This structure/specimen is with butyl rubber plate which is sandwiched between two aluminum plates. The dimensions of the specimen are with length 350mm (with 50mm constrained at one end) and width 50mm.The thickness of the specimen may be vary and depends upon the thickness of Viscoelastic Damping Material (VDM) i.e. Butyl Rubber. The Main objective of the finite element modal analysis here is to study the effect of impact location on natural frequency and Frequency Response Function (FRF) especially in terms of acceleration magnitude for composite structure/specimen.
