ANALISIS DESAIN KEKUATAN RANGKA ALAT PENGUKUR KEKAKUAN SPRING VALVE MOTOR BEBEK 4-TAK MENGGUNAKAN METODE FEA

The Spring Valve Stiffness Measuring Tool for 4-Stroke Motorcycles is a device designed by Argy Shalom Ramadhan to enhance workshop operational efficiency. Although the design process has been completed, structural strength analysis was not included in the development phase. This study aims to analyze the frame strength using the Finite Element Analysis (FEA) method with Autodesk Inventor 2023 software. The analysis encompasses evaluations of von Mises stress, strain, deformation, and safety factors to assess the structure's performance under various loading conditions. Simulation results reveal that under a load of 3,000 N, the maximum von Mises stress reached 2,094 MPa, the maximum strain was 0.008503 µl, maximum deformation was 18.01 mm, and the minimum safety factor was 0.1. In contrast, under a 40 N load, the maximum von Mises stress was 27.92 MPa, maximum strain was 0.0001134 ul, maximum deformation was 0.2402 mm, and the minimum safety factor was 7.41 ul. This study highlights that the FEA method provides critical insights into stress distribution, strain, deformation, and safety factors within the structure. These results enable tool optimization to ensure safety and reliable performance.
