Abstract

Roda kereta merupakan komponen vital dalam sistem perkeretaapian yang harus mampu menahan beban operasi secara aman dengan deformasi dan konsentrasi tegangan yang terkendali. Penelitian ini bertujuan untuk mengevaluasi dan membandingkan performa struktural dua desain roda kereta melalui pendekatan Finite Element Analysis (FEA). Analisis dilakukan menggunakan ANSYS Workbench 17.2 dengan memodelkan kontak roda dengan rel menggunakan tipe kontak frictionless agar kondisi batas lebih merepresentasikan kondisi operasi nyata. Material yang digunakan adalah baja karbon ASTM A36 sebagai pendekatan baseline, dengan pembebanan vertikal sebesar 110.362,5 N yang merepresentasikan setengah beban gandar jalur rel kelas I. Parameter evaluasi meliputi tegangan ekuivalen Von Mises, total deformasi, dan safety factor. Hasil simulasi menunjukkan bahwa Model B memiliki performa struktural yang lebih baik dibandingkan Model A, ditunjukkan oleh tegangan maksimum yang lebih rendah (160,82 MPa dibandingkan 195,19 MPa), deformasi maksimum yang lebih kecil (0,029245 mm dibandingkan 0,045356 mm), serta nilai safety factor minimum yang lebih tinggi (1,3742 dibandingkan 1,1322). Perbedaan kinerja ini dipengaruhi oleh variasi geometri, khususnya pada web plate, radius transisi, dan distribusi massa roda. Penelitian ini memberikan kontribusi berupa pemahaman pengaruh geometri terhadap respons struktural roda kereta dan dapat digunakan sebagai dasar evaluasi awal desain roda kereta menggunakan pendekatan FEA.

Abstract

This study presents a comparative analysis of the structural strength of two railway axle models using the Finite element analysis (FEA) method. The objective is to determine the effect of geometric variations on stress distribution, total deformation, and safety factor of the railway axle. Three-dimensional models of both axle designs were developed using CAD software and analyzed through the Static Structural module in ANSYS Workbench 17.2. The material used is ASTM A36 carbon steel with a static load of 196,133 N, representing the axle load of a railway system. Simulation results show that Model A exhibits better structural performance, with a maximum Von Mises stress of 136.72 MPa, maximum deformation of 0.10697 mm, and a minimum safety factor of 1.6164. In contrast, Model B produces a higher maximum stress of 163.64 MPa and a total deformation of 0.15741 mm, with a lower minimum safety factor of 1.3505. These differences indicate that geometry significantly affects the load distribution and structural stability of the axle. Overall, Model A is considered more optimal due to its higher stiffness and greater safety margin, making it more suitable for railway axle design applications that require high vertical load resistance and low fatigue risk.

Abstract

The dismantling process of industrial chimneys requires a safe and reliable lifting system, in which the lifting lug serves as a critical component for transferring loads to the lifting equipment. Improper lifting lug design may lead to significant safety risks during the lifting of segmented structures. This study aimed to evaluate the structural strength of a lifting lug design used in a staged chimney dismantling process using Finite Element Analysis (FEA). The chimney was divided into three loading conditions representing different segment masses, namely segments 1–5, 6–14, and 15–23. The analysis was conducted using SolidWorks Simulation with ASTM A36 structural steel and static loading assumptions. The evaluated output parameters included Von Mises stress, Von Mises strain, and total deformation. The simulation results indicated maximum Von Mises stresses of 76.85 MPa, 101.8 MPa, and 81.62 MPa for each segment group, all of which were below the material yield strength of 250 MPa. The maximum Von Mises strain remained within the elastic range, with the highest value of 77.97 MPa. The total deformation was relatively small, with maximum displacement values below 0.6 mm for all loading cases. These results demonstrate that the analyzed lifting lug design is structurally safe and suitable for application in staged chimney dismantling operations.
