Abstract
This research aims to investigate the stress and deformation behavior of banana fiber extraction machine blades using the Finite Element Method (FEM). Three blade configurations—5-blade, 13-blade, and 32-blade designs—were analyzed and compared in terms of Von Mises stress, deformation, safety factors, and fatigue life. The results indicate that the 5-blade configuration exhibited the lowest stress value of 6.4 MPa and the highest safety factors (Goodman = 12.87, Soderberg = 12.42, and general FoS = 4.69), along with an exceptionally long fatigue life estimated at 2.80 × 10²¹ cycles. While the 13-blade and 32-blade configurations experienced higher stress levels, they demonstrated better load distribution and less deformation. All blade designs operated within the elastic range of the material. The findings provide valuable insights for optimizing blade design to enhance structural integrity, safety, and operational performance of banana fiber extraction machines.
