Abstract

Bogie Machine Test merupakan alat penting dalam industri perkeretaapian yang digunakan untuk menguji integritas mekanis bogie, yaitu komponen vital yang menghubungkan badan kereta dengan sistem roda. Seiring meningkatnya kebutuhan transportasi kereta api yang efisien dan aman di Indonesia, dibutuhkan perangkat pengujian bogie yang andal dan memiliki struktur rangka yang kuat. Proyek akhir ini bertujuan untuk merancang dan menganalisis struktur rangka baru pada Bogie Machine Test agar mampu menahan beban hidrolik statis maksimum hingga 100 ton.
Penelitian ini menggunakan metode elemen hingga (Finite Element Method) untuk mengevaluasi tegangan von Mises, deformasi total, faktor keamanan (safety factor), dan kekakuan lentur (bending stiffness) pada dua model frame: desain lama dan desain baru. Metodologi meliputi pemodelan CAD, perhitungan pembebanan struktural, proses meshing, dan validasi boundary condition. Hasil analisis menunjukkan bahwa desain frame baru memberikan peningkatan performa struktural yang signifikan. Tegangan maksimum pada frame baru hanya 145,53 MPa, deformasi total sebesar 0,536 mm, dan safety factor mencapai 1,718—berbanding terbalik dengan desain lama yang mengalami tegangan hingga 396,2 MPa, deformasi 2,326 mm, dan safety factor kurang dari 1,0.
Selain itu, desain frame baru menunjukkan peningkatan kekakuan lentur, pergeseran lokasi tegangan kritis ke area yang lebih aman, serta peningkatan kinerja mekanik secara keseluruhan. Hasil ini membuktikan bahwa desain yang telah dioptimasi lebih aman, lebih kaku dalam menahan beban lentur, dan mampu memenuhi kebutuhan pembebanan maksimum untuk pengujian bogie.

The Bogie Machine Test is a crucial tool in the railway industry, used to evaluate the mechanical integrity of bogies, which are vital components that connect the train body to the wheel system. With the increasing demand for efficient and safe rail transportation in Indonesia, a reliable and structurally sound bogie testing device has become essential. This final project aims to design and analyze a new frame structure for the Bogie Machine Test to ensure its capability to withstand a maximum static hydraulic load of 100 tons.
The research applies Finite Element Method (FEM) simulations to assess the von Mises stress, total deformation, safety factor, and bending stiffness on two frame models: an existing frame design and a newly proposed one. The methodology includes CAD modeling, structural loading calculations, meshing, and boundary condition validation. Comparative analysis reveals that the new frame design offers significant structural improvements. It produces lower maximum stress (145,53 MPa), minimal deformation (0.536 mm), and a high safety factor (1.718), compared to the old design which exceeds material yield strength (396.2 MPa) and shows greater deformation (2.326 mm) with a safety factor below 1.0.
Furthermore, the new frame design demonstrates higher bending stiffness, redistributed critical stress locations to safer areas, and improved mechanical performance overall. The results confirm that the optimized design is safer, more durable, and capable of supporting the maximum load requirements for bogie testing applications.
