Abstract

Mobilitas manusia modern dan meningkatnya perekonomian menuntut perkembangan sarana transportasi yang cepat, murah dan aman. Kebutuhan transportasi publik di Indonesia dijawab dengan pengadaan kereta ringan yaitu Light Rail Transit (LRT), sebagai salah satu moda transportasi pilihan yang beroperasi dalam kota. LRT diproduksi oleh PT. INKA untuk digunakan di Palembang dan Jakarta demi menyukseskan penyelenggaraan Asian Games 2018. Namun, tingkat kandungan dalam negeri (TKDN) LRT ini masih tergolong rendah, disebabkan bogie system yang digunakan masih merupakan produksi Bombardier, Inggris. Disisi lain, kemampuan PT. INKA untuk memproduksi rangka bogie kereta api perlu dikembangkan, sehingga juga dapat memproduksi rangka bogie untuk LRT. Oleh karena itu, diperlukan studi pengembangan bogie system dengan muara pemanfaatan produksi bogie system dalam negeri dan peningkatan TKDN. Penelitian ini merupakan tahapan awal pengembangan bogie system, yang mana dimulai dari analisis struktur rangka (frame) bogie. Pada penelitian ini, perangkat lunak Inventor Professional 2015 digunakan untuk membangun model solid dan Ansys Workbench R18 digunakan sebagai media studi numerik. Tipe analisis yang dilakukan disini berupa analisis struktur statis. Analisis struktur statis dilakukan untuk mengetahui tingkat keamanan rangka bogie. Merujuk kepada standar EN 13749, ada 2 variasi pembebanan yang digunakan yaitu switches dan running through curves. Setelah dilakukan simulasi, didapatkan beberapa poin yaitu tegangan von-mises dan faktor keamanan dari kasus pembebanan switches memiliki pengaruh yang lebih besar terhadap struktur bogie. Setelah dilakukan simulasi maka didapatkan nilai tegangan von-mises dan faktor keamanan yang berbeda. Pada kondisi pembebanan switches didapatkan tegangan von-mises maksimum sebesar 319.66 MPa dan faktor keamanan terkecil sebesar 1.0167. Pada kondisi pembebanan running through curves didapatkan tegangan von-mises maksimum sebesar 311.09 MPa dan faktor keamanan terkecil sebesar 1.0447. ==============================================================Modern human mobility and increasing economy matters demanding development of transportation which fast, cheap and safe. The demand of public transportation in Indonesia answered by creating light train which is Light Rail Transit (LRT), for one of the prefered modes of transportation operating within the city. LRT produced by PT.INKA used in Palembang and Jakarta to succeed of Asian Games 2018. However, specific level of domestic component (TKDN) classified as very low, because bogie system produced by Bombardier, England. On the other hand, capability of PT.INKA in produce bogie frame need to be improved, so PT.INKA can also produce LRT bogie frame. Therefore, is required bogie system devepolment study for production of domestic bogie and increase specific of domestic component (TKDN). This research is an early stage of development bogie system, which starts with bogie frame structural analysis. In this research, Inventor Professional 2015 software used for make solid model dan Ansys Workbench R18 used as finite element method software for numerical study media. Type of analysis that used in this research is static structural. Static structural analysis used to know the safety of bogie frame. Referring to EN 13749 standart, there are 3 load cases that used that is switches, running through curves and running through curves based on track radius. There are points obtained after simulation done, von-mises stress dan safety factor from switches load case have more influence to bogie structure. After simulation done the result of von-mises stress dan safety factor that obtained is different. On switches load case obtained maximum von-mises stress of 319.66 Mpa dan minimum safety factor of 1.0167. On running through curves load case obtained maximum von-mises stress of 311.09 Mpa dan minimum safety factor of 1.0447.
