Stress and Fatigue Simulation of Structural Blades in Mechanical Clearing Operations

Abstract

This study presents a numerical investigation into the structural performance of the cutting blades used in vegetation-clearing operations, particularly within mechanical systems designed for demining or land maintenance. Using finite element analysis (FEA), the research evaluates stress distribution, fatigue behavior, and failure risk under cyclic loading conditions. Multiple simulation models were developed to replicate realistic operational forces and identify critical stress concentration zones. The fatigue simulations provided insights into lifetime predictions and cumulative damage evolution, expressed through percentage-based degradation maps. Von Mises stress analyses further validated the structural response of the blades under high-load scenarios. The results indicate that proper geometric configuration and material selection are essential for improving fatigue life and ensuring operational safety in harsh environments. The proposed methodology supports optimization efforts in blade design for enhanced durability and reliability.
