Caracterización de las propiedades físicas y modales de los raquis de racimos de mbocayá para recolección mecanizada

Abstract

The Mbocaya palm (Acrocomia aculeata) is an alternative for the production of biodiesel due to the characteristics of the plant such as the great adaptability to different climates and high production of oil. However, its exploitation remains an obstacle. Since the development of efficient machines for harvesting and post-harvesting of the macaw palm requires the study of the dynamic behavior of the plant, the finite element method can be used in machine design to study the dynamic behavior of the plant. As input parameters for using the finite element method, they should be informed about the geometrical, physical and mechanical system under study. The aim of this study was to determine and evaluate the geometric and physical properties of the rachis of Mbocaya palm, in addition to investigating the transmissibility and frequency sweep by means of mechanical vibrations, at different stages of maturation. It was concluded that the physical and geometric properties were fundamental for the construction of the model and understanding of the dynamic behavior of Mbocaya palm rachis. In the evolution of the maturation stage from immature to mature, the first natural frequency changes in magnitude from 22.66 to 15.90Hz.
