Abstract

Kereta api merupakan transportasi massal, seperti yang banyak dijumpai yaitu kereta penumpang tidak hanya mengangkut penumpang saja kini transportasi kereta juga bisa mengangkut barang. Kereta pengangkut barang atau yang biasa disebut dengan flat wagon memiliki jenis khusus dalam pengangkutan barang. Pada proyek akhir ini akan dibahas tentang bogie, bogie sub-sistem penting dalam desain kereta api yang berperan dalam menopang dan mengatur roda kereta. Proyek akhir ini hanya meneliti bogie frame yang terdiri dari rangkaian 2 side frame dan transom yang dihubungkan dalam 1 kesatuan menjadi bogie frame pada kereta flat wagon. Standar yang digunakan dalam desain dan konstruksi bogie kereta api bervariasi tergantung pada negara, produsen, dan jenis kereta api. Analsis struktur statis ini dilakukan dengan merujuk pada standar EN-13749 untuk mengetahui tingkat keamanan dari bogie frame kereta flat wagon. Perangkat lunak yang digunakan kali ini yaitu Inventor Student Version 2020 yang digunakan dalam pembuatan desain dari model solid, dan menggunakan Ansys Workbench sebagai analisis simulasi. Setelah dilakukan simulasi didapatkan beberapa poin yaitu principal stress dan directional deformation dari 6 kasus pembebanan yang dilakukan. Didapatkan nilai tegangan maksimal dan deformasi maksimal yang berbeda-beda tiap load case. Tegangan maksimal dan nilai deformasi tertinggi terjadi pada load case 1 dimana kereta menerima full load saja dalam kondisi kereta diam atau bergerak dengan kecepatan tetap atau gaya normal. Tetapi tegangan maksimal yang keluar tidak melebihi batas yield stress sehingga kereta masih dinyatakan aman apabila terkena beban eksepsional, bagian yang terkena critical area bisa dilakukan dengan penggantian ketebalan dari plat tersebut.

Trains are mass transportation, as is often found, passenger trains not only carry passengers, now train transportation can also transport goods. Goods transport trains or what are usually called flat wagons are a special type of goods transporter. In this final project we will discuss bogies, bogies, an important sub-system in train design which plays a role in supporting and adjusting the train wheels. This final project only examines the bogie frame which consists of a series of 2 side frames and a transom which are connected in one unit to form a bogie frame on a flat wagon train. The standards used in the design and construction of railroad bogies vary depending on the country, manufacturer, and type of train. This static structural analysis was carried out by referring to the EN-13749 standard to determine the safety level of the flat wagon bogie frame. The software used this time is Inventor Student Version 2020 which is used to create designs from solid models, and uses Ansys Workbench as simulation analysis. After carrying out the simulation, several points were obtained, namely principal stress and directional deformation from the 6 loading cases carried out. The maximum stress and maximum deformation values obtained are different for each load case. The maximum stress and highest deformation value occur in load case 1 where the train receives full load only when the train is stationary or moving at a constant speed or normal force. However, the maximum stress that comes out does not exceed the yield stress limit so that the train is still declared safe if it is exposed to exceptional loads. The parts affected by critical areas can be replaced by changing the thickness of the plate.
