Abstract

The research evaluates the durability of the ESAF frame using finite element analysis (FEA). The simulation examines von Mises stress, displacement, and safety factor under load variations of 300 kg, 350 kg, and 400 kg. Results show von Mises stress values of 305.5 MPa, 356.3 MPa, and 406.8 MPa, which are within the tensile strength range of high-strength low alloy steels (HSLA) at 750–1500 MPa, indicating structural safety. Displacement values are 0.03131 mm, 0.03652 mm, and 0.04174 mm, with minimal deformation demonstrating stability. Safety factor values are 5.0, 4.2, and 3.75, exceeding the safe limits of 3.0 for dynamic and 2.0 for static loads based on journal references. These findings confirm that the ESAF frame is theoretically safe for the given load conditions.

Abstract

Failure of slip yoke components in palm oil transport vehicle transmission systems is generally caused by complex and cyclic dynamic loading. This study aims to analyze stress distribution and predict failure locations using a Metode Elemen Hingga (FEM)-based approach. A three-dimensional model was developed from actual geometry with controlled simplification using AISI 4140 material. Mesh convergence and quality evaluation were conducted to ensure numerical reliability. The results show that maximum stress increases with load, reaching 196.14 MPa, 294.38 MPa, 392,40 MPa, and 490.52 MPa for loads of 4, 6, 8, and 10 tons, respectively. At 10 tons, the stress exceeds the material yield strength (415 MPa), indicating plastic deformation. Stress concentration occurs at the critical section (C–C) due to geometric discontinuities and combined loading, consistent with observed failure locations. Comparison with analytical results shows less than 1% deviation, confirming model accuracy. This study demonstrates that FEM effectively predicts stress distribution and failure mechanisms, providing a basis for design optimization and maintenance strategies.
