GOMES, Ely Queiroz; SANTOS, Fábio Lúcio; NASCIMENTO, Moysés y ZANELLA, Marco Antonio. Transmissibility of coffee fruit-peduncle-branch systems submitted to vibration induced by impact. Dyna rev.fac.nac.minas [online]. 2020, vol.87, n.214, pp.61-65. Epub 30-Oct-2020. ISSN 0012-7353. https://doi.org/10.15446/dyna.v87n214.85186.
The development of efficient machines for coffee harvesting requires solid knowledge about the dynamic behavior of the plant. Vibration transmissibility is a parameter on dynamic behavior that may help understand this process. The aim of this study was to evaluate the average vibration transmissibility in coffee fruit-peduncle-branch samples containing unripe and ripe fruits. The experiments were performed using Arabica coffee plants of the cultivar Catuaí Vermelho. The samples were submitted to three vibration frequency levels, 20, 30 and 40 Hz, induced to the branch with impact of rigid fiberglass rods moving at a constant amplitude 2 mm. Data on acceleration were collected using an accelerometer fixed to the branch. The frequency of 20 Hz presented the highest transmissibility. Samples containing ripe fruits also presented high transmissibility when compared to those containing unripe fruits.
