A Portable device to illustrate two methods for vibration reduction namely tuned dynamic absorber and isolation mounting

Abstract

Mechanical vibrations can be harmful to structures as well as to humans. It is important to understand the principles of design that are used in developing various methods for reducing vibration. There are several tools at our disposal to reduce the vibrations transmitted from a vibration machine to the building structure. Two commonly available methods of vibration control are using passive vibration isolation mountings and tuned mass absorbers. This paper presents the design and working of a portable device to illustrate both methods of vibration reduction. We can examine the performance of both mounting and absorber using this physical device. The analytical and experimental work shows that such a device can effectively illustrate the principles involved in the design of mountings and absorbers. Also, the device can be used to show the influence of various physical parameters on performance. The presentation will also include the discussion on the role of such devices in enhancing the understanding of design principles in acoustics, noise, and vibration.
