Ítem Design and construction of a transducer for bite force registration.(ELSEVIER SCI LTD, 2009-05-29) Isaza JF; Throckmorton GS; Roldán SI; Universidad EAFIT. Departamento de Ingeniería Mecánica; Bioingeniería GIB (CES – EAFIT)This study describes the development of a system for quantification of human biting forces by (1) determining the mechanical properties of an epoxy resin reinforced with carbon fiber, (2) establishing the transducer's optimal dimensions to accommodate teeth of various widths while minimizing transducer thickness, and (3) determining the optimal location of strain gages using a series of mechanical resistance and finite element (FE) analyses. The optimal strain gage location was defined as the position that produced the least difference in strain pattern when the load was applied by teeth with two different surface areas. The result is a 7.3-mm-thick transducer with a maximum load capacity beyond any expected maximum bite force (1500N). This system includes a graphic interface that easily allows acquisition and registration of bite force by any health-sciences or engineering professional.Ítem Design and construction of a transducer for bite force registration.(ELSEVIER SCI LTD, 2009-05-29) Isaza JF; Throckmorton GS; Roldán SI; Universidad EAFIT.

Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)This article describes a measurement method whit strain gages, which allows measure the vertical force independently of the lateral force in the wheel - Track interface of a railway. It also shows the obtained results from the implementation of this method to measure the forces in a commercial railway of the railway system. © JVE International Ltd.Ítem Manual de utilización de transductores y sistemas de adquisición de datos del laboratorio de mecánica experimental(Universidad EAFIT, 2009) Sánchez Pulgarín, Javier Hernán; Pineda Botero, Fabio Antonio
