Abstract

Pertumbuhan sektor perkeretaapian menjadi fokus utama dalam pengembangan infrastruktur transportasi di berbagai negara, termasuk Indonesia. Salah satu upaya penting dalam menjaga kualitas jalur kereta api adalah pengukuran secara berkala menggunakan Railway Measuring Equipment 2.0. Penelitian ini bertujuan untuk menganalisis struktur frame dari Railway Measuring Equipment 2.0 guna mengurangi massa alat tanpa mengorbankan kekuatan struktural, dengan pendekatan metode Finite Element Analysis. Frame lama yang terbuat dari besi kanal C memiliki bobot 24 kg dan dianggap terlalu berat untuk operasional lapangan. Desain baru dimodelkan menggunakan Autodesk Inventor dan dianalisis dalam ANSYS dengan tiga variasi material: ASTM A500, Aluminium 6063, dan Stainless Steel 304. Metode FEA digunakan untuk menganalisis tegangan Von Mises, deformasi, safety factor. Setelah dilakukan penelitian, frame lama memiliki nilai tegangan Von Mises maksimum 2,956 MPa (pembebanan statis) dan 3,9331 MPa (akselerasi), sedangkan frame baru menghasilkan nilai tegangan Von Mises: untuk ASTM A500 sebesar 4,8935 MPa (statis) dan 7,1855 MPa (akselerasi), Al 6063 sebesar 6,3643 MPa (statis) dan 7,9358 Mpa (akselerasi), serta SS 304 sebesar 4,8923 MPa (statis) dan 7,2105 MPa (Akselerasi). Semua nilai tersebut jauh di bawah tegangan luluh material yang digunakan. Deformasi total frame lama adalah 0,00617 mm (statis) dan 0,0100 mm (akselerasi) dan pada frame baru A500 (0,10074 mm statis, 0,048757 mm akselerasi), Al6063 (0,10942 mm statis, 0,12627 mm akselerasi), dan SS304 (0,04278 mm statis, 0,0502 mm akselerasi). Nilai bending stiffnes frame lama sebesar 694,88 kN/mm, sementara desain baru memiliki nilai kekakuan 452,38 kN/mm (ASTM A500), 351,59 kN/mm (Al 6063), dan 445,26 kN/mm (SS 304). Dari segi pengurangan massa, frame baru memberikan pengurangan yang signifikan, yaitu 68,99% untuk ASTM A500, 84,53% untuk Al 6063, dan 68,56% untuk SS 304.

The growth of the railway sector has become a key focus in the development of transportation infrastructure in various countries, including Indonesia. One important effort to ensure railway track quality is periodic measurement using Railway Measuring Equipment 2.0. This study aims to analyze the frame structure of the Railway Measuring Equipment 2.0 in order to reduce the overall mass of the device without compromising structural strength, using the Finite Element Analysis (FEA) method. The old frame, made from C-channel steel, weighed 24 kg and was deemed too heavy for field operations. A new frame design was modeled using Autodesk Inventor and analyzed in ANSYS with three material variations: ASTM A500, Aluminum 6063, and Stainless Steel 304. The FEA method was used to evaluate Von Mises stress, deformation, and safety factor. The old frame showed a maximum Von Mises stress of 2.956 MPa under static loading and 3.9331 MPa under acceleration. In contrast, the new frame generated higher stresses: 4.8935 MPa (static) and 7.1855 MPa (acceleration) for ASTM A500; 6.3643 MPa and 7.9358 MPa for Aluminum 6063; and 4.8923 MPa and 7.2105 MPa for SS 304. These values were all far below the yield strength of each material. Total deformation in the old frame was 0.00617 mm (static) and 0.0100 mm (acceleration), while in the new frame: ASTM A500 showed 0.10074 mm (static) and 0.048757 mm (acceleration); Aluminum 6063 showed 0.10942 mm (static) and 0.12627 mm (acceleration); and SS 304 showed 0.04278 mm (static) and 0.0502 mm (acceleration). The bending stiffness of the old frame was 694.88 kN/mm, while the new designs achieved 452.38 kN/mm (ASTM A500), 351.59 kN/mm (Al 6063), and 445.26 kN/mm (SS 304). In terms of weight reduction, the new frames showed significant decreases: 68.99% for ASTM A500, 84.53% for Al 6063, and 68.56% for SS 304.
