Abstract

The utilization of vibration analysis on the tapered beam significantly enhances the engineering investigation and design process. It is notable that the width of the tapered beam exhibits variation along its length, while the height remains constant. Experimental modal testing aims to determine modal factors such as natural frequency, damping, and mode shapes. A comparative study is presented in this paper, examining the vibrational characteristics of tapered beams composed of copper, stainless steel, and Copper-Aluminium composite under different boundary conditions. Both experimental and numerical approaches are employed for this purpose. The excitation of the beam is achieved using an impact hammer, while a laser vibrometer captures the ensuing response. Signal conversion from the time domain to the frequency domain is carried out using the Fast Fourier Transform in MATLAB software. A comparison is made between the experimental findings and the numerical results generated by COMSOL 5.6v, a finite element modeling software. Investigation and analysis of the modal properties of the tapered beams, particularly its natural frequency and mode shape, are essential for enhancing design robustness.

Keywords: Tapered beam, Modal analysis, Laser Vibrometer, Composite, Impact hammer.
