Use of Smartphone Applications in Vibration Analysis : Critical Review

Abstract

Introduction: The use of vibration analysis in the industry has become more and more frequent and has become a powerful tool to guarantee the reliability of machines and equipment. Something that has been noticed, however, is that this technique is restricted to a minority of companies due to the high cost of equipment and specialized labour. Objective: to gather and define a systematic, objective and practical way as main characteristics of the analysis of vibrations by means of smartphones and to propose the possibility of new applications both in the industry and in the mandatory education to popularize it. Methods: A bibliographic search was performed with the search for the term "vibration analysis smartphone apps". Studies with titles not directly related to the research topic, older studies and studies that relate repeated strategies were excluded. Results: It is possible to identify resonance problems, vibration limit violations. Very easy to use and low cost. Conclusion: The use in the academic environment from basic education to higher education is possible due to the simplicity of handling which would make the practice more popular. For application in the industry it is possible to use external sensors and the results from the smartphone. The results found open up several interesting questions for future research. First, it is possible to improve applications as new technologies are developed on smartphones. Second, it is possible to make the technique popular by including its teaching in basic education.
