“…To facilitate the understanding of this study, the main strategies used to determine the applications of smart phones in vibration analysis and the criteria for evaluating their effectiveness were divided into three important pillars: I -Teaching (T) and II -Field (F). A free fully functional test / student version of the "iDynamics" application for vibration analysis can be downloaded from the Institute for Structural and Dynamic Analysis at the University of Kaiserslautern [1] which indicates that at a higher-level smartphone are already being used, although on a small scale, in the academic environment. The iDynamics is an app for teaching and learning purposes.…”

“…What is almost unknown in the engineering community are the increased capabilities and possibilities of mobile devices to be used in the field of vibration analysis, systems identification and structural monitoring. In addition to advanced performance and increased storage capacity, different hardware components such as accelerometers and gyroscopes have improved considerably [1]. Another important feature of vibration system is whether the ability to remain accurate over velocity.…”

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.

ResumenEl avance continuo de la tecnología en los teléfonos móviles ha facilitado el desarrollo de aplicaciones más complejas y especializadas. En la actualidad se pueden encontrar aplicaciones móviles sencillas para el cálculo de estructuras. En este trabajo, se da un paso más con una nueva aplicación para análisis dinámico. Más concretamente, se ha desarrollado una aplicación móvil que permite valorar el estado de servicio de vibraciones en estructuras y que puede ser utilizada tanto por profesionales como para la impartición de cursos de master en análisis dinámico. En este artículo se muestran los resultados obtenidos con la aplicación desarrollada, DynApp, en diversas pasarelas peatonales de la ciudad de Madrid. Estas campañas experimentales se han realizado por los alumnos de dos cursos de master de la Escuela de Caminos de la UPM: Análisis Experimental de Estructuras y Análisis Dinámico y Sísmico de Estructuras.AbstractThe continuous advance of smartphone technologies has promoted the development of more complex and specialized mobile apps. Currently, it is possible to find several mobile apps that can be used for simple structural analysis. Here, a further step towards a newly specialized app for dynamic analysis is taken. More precisely, an app for the vibration serviceability assessment of structures has been developed, which is useful for professional practitioners and for imparting master courses on dynamic analysis. This paper presents experimental tests using the developed app, DynApp, on several in-service footbridges sited in Madrid. The tests have been done within two master courses imparted at ETSI Caminos of UPM: Experimental Analysis of Structures and Dynamic and Seismic Analysis of Structures.

Bushing is a part of rubber curing machine that have function as cushion pin joint , generally make from a bronze material. Pin joint have a function to connected with 1 paired linkage arm with rotated crank gear of each via pin joint to get closing force at rubber curing machine when mould closed. When bushing condition at pin joint on rubber curing machine was not good caused by friction. It will make closing force linkage arm left and right ( 1 paired ) on rubber curing machine unbalanced. So it will make closing force to force closed rubber mould undistributed evenly, so it caused mould rubber closed with gap. This condition will make defect rubber product open mould after cured finished. In this case is important to find new methode detection and monitored bushing condition. This research was done by measured vibration around pin joint at linkage arm by taking data of sound and acceleration on the real object research and used 2D software simulator to measured bushing condition good or not. Acceleration measurement was done by measured at axis Y and Z by used accelerometer sensor, and accelero sensor on cell phone via sains journal android application. And collected the data stress value on linkage arm by used nidle dial gauge millimeter scale. By simulation software are measured acceleration at axis X and Y with good bushing condition or vise versa.The actual data that was collected : acceleration, sound vibration and stress value and simulated data by software to be compare the amplitude and choose the biggest amplitude as new methode measurement of vibration to detect and monitor bushing condition.From the result data, detection of vibration around pin joint by acceleration value by used accelerometer sensor measured at axis Y and Z more prefer with the other measurement methode.
