Investigation of Two Ferromagnetic Damping Materials in Conjunction with Initial Development of a Signal Analyzer Interface Program.
Abstract
A promising method for the attenuation of shipboard vibration and noise utilizes constituent materials whose composition and microstructure combine to absorb energy internally and dissipate it. However, the alloy design of damping materials which possess both significant energy-absorption capacities and alos necessary strength levels is difficult. Presently, there are several problems associated with designing a material with high damping characteristics. On of these involves the development of efficient, reliable and reproducible methods for measurement of material damping capacities. In this study, the primary area of interest concerned the development of microcomputer analysis techniques to study the vibration damping response of twi iron-chromium (Fe-Cr)-based alloys. The present research utilized a Zenith Corporation Z-150 microcomputer to compose programming that captures, stores, and analyzes the damping data produced by various Fe-Cr-based alloy specimens. The computer programming developed in the present research enables an interface of the Zenith Z-150 computer with a Scientific Atlanta SD380Z Signal Analyzer.
