- PublicaciónAcceso abiertoDiseño de sólido resonador para partes del cuerpo (muslos) por medio de pruebas experimentales y elementos finitos(2019) Mora Saldarriaga, María Camila; Franco Bedoya, Ramiro EstebanIn the present work, experimental tests were carried out on adults of different body types and gender, both male and female, to obtain the frequencies of less attenuation for the thighs; having as a result for the high part 83Hz, middle part 91 Hz and low part 106 Hz. Subsequently, the design of solid resonators was made for the frequencies obtained for each part of the thighs. To obtain the resonant solids, we studied the solution of the acoustic wave equation in a beam embedded in both ends by initial conditions and the boundary conditions of the system. To validate the results, the numerical simulation was carried out using the finite element method (FEM). According to the results obtained, the design of the resonant solids is useful for the amplification of the vibrations at the frequencies to which they were tuned
- PublicaciónAcceso abiertoDiseño de sólidos resonadores para el desarrollo de una experiencia interactiva vibrotáctil por medio de pruebas experimentales y elementos finitos(2019) Otálvaro Hoyos, Juan Esteban; Figueroa Cuellar, Daniel Stiven; Franco Bedoya, Ramiro EstebanIn the present paper, experimental tests were carried out on adults of different contextures and gender, both male and female, to obtain the frequencies of less attenuation for the hands, feet and back; Resulting in hands, a frequency of 112 Hz for the palm and 184 Hz for the fingers. For the feet, a frequency of 182 Hz was obtained for the fingers, 75 Hz and 80 Hz for the heel, for the instep 80 Hz, 81 Hz and 93 Hz. Finally, for the back part there are frequencies of 54 Hz for the central part, 65 Hz for the right part and 75 Hz for the left part. Subsequently, the design of solid resonators for the different frequencies was carried out. To obtain the resonant solids, we have studied the solution of the acoustic wave equation in a beam embedded in both ends by the initial conditions and the boundary conditions of the system. To validate the results, the numerical simulation was carried out using the finite element method (FEM), according to the results obtained, the design of the resonant solids is useful for the amplification of the vibrations at the frequencies to which they were tuned
