Abstract
In this work, the experimental and finite element simulation solutions of vibration characteristics of the Mg-Al/Mg2Si composite has been carried out. The influence of the geometrical structures, percentage of bismuth and material properties on the natural frequency and the material damping of the Mg-Al/Mg2Si composites has been studied. The fast fourier transform (FFT) analyzer has been utilized to find the first three natural frequencies and the modal damping experimentally of the said composite. Finite element simulation method also has been adopted to find the natural frequencies and their mode shapes for the Mg-Al/Mg2Si composites specimens. From the results of the experimental and analytical method it is identified that the composite material exhibits the set of natural frequencies and the modal damping. It is also observed that the modal damping increases with increase in the addition of bismuth.
