Abstract

Peningkatan kebutuhan akan transportasi di Indonesia berbanding lurus dengan perkembangan transportasi di Indonesia. Salah satu langkah pemerintah dalam menghadapi hal ini adalah dengan meningkatkan (TKDN) pada komponen kereta Perkembangan mengenai kereta ringan telah dilakukan di beberapa komponen penyusun kereta ringan itu sendiri dimana salah satunya adalah perkembangan mengenai peralatan perangkai yang selanjutnya disebut sebagai Coupler. Pada penelitian sebelumnya yang dilakukan oleh A.David dan Izzan, telah menghasilkan sebuah prototipe Automatic Coupler untuk kereta ringan dan rentang kecepatan yang diperlukan saat proses coupling. Agar nantinya Automatic Coupler ini dapat melakukan proses coupling secara sempurna perlu dilakukan analisis kinematika secara menyeluruh di setiap komponen.
Dalam melakukan tugas akhir model yang digunakan adalah Automatic Coupler kereta ringan yang telah didesain oleh A.David dan dimodifikasi oleh Izzan yang mengacu pada standar EN 16019:2014 dengan pembebanan kereta ringan mengacu pada ASME RT-1-2010. Dengan menggunakan pembebanan ini, dilakukan perhitungan secara manual tentang gaya longitudinal yang terjadi pada model kereta ringan tersebut dimana gaya longitudinal ini akan menjadi input gaya bagi Automatic Coupler untuk melakukan proses coupling. Setelah dilakukan perhitungan pembebanan dilakukan Analisis Lintasan untuk mengetahui apakah Coupler dapat melakukan proses coupling. Dimensional Synthesis digunakan untuk mendapatkkan perubahan posisi pada link dan joint Coupler ketika melakukan proses coupling. Simulasi numerik dilakukan untuk mengetahui kekuatan ikatan.
Dari hasil penelitian yang telah dilakukan, didapatkan bahwa ikatan kuat Coupler terjadi ketika posisi Coupled hooked plate dan coupling link membentuk formasi jajaran genjang. Dimesional Synthesis menghasilkan geometri dan batas batas posisi gerakan dari komponen Coupler. Dari hasil simulasi statis menggunakan material AISI 1045 menghasilkan peningkatan kekuatan ikatan dengan gaya resultan ∑▒〖F=0〗 dan peningkatan resultan sebesar 6,9 N. Terjadi penurunan tegangan akibat beban tarik pada hooked plate dari 1183 Mpa menjadi 810 Mpa. Terdapat peningkatan tegangan pada pembebanan tekan dari 480 Mpa menjadi 577 Mpa dengan tegangan maksimum pada hooked plate.

The increasing need for transportation in Indonesia is directly proportional to the development of transportation in Indonesia. One of the government's steps in dealing with this is to increase (TKDN) on the train component. Developments regarding the Light train have been carried out in several components of the Light train itself, one of which is the development of the coupling equipment hereinafter referred to as the Coupler. In previous research conducted by A.David and Izzan, has produced a prototype Automatic Coupler for Light trains and the required speed range during the coupling process. So that later this Automatic Coupler can carry out the coupling process perfectly, it is necessary to do a thorough kinematics analysis of each component.
In carrying out the final project, the model used is the Light rail Automatic Coupler which has been designed by A.David and modified by Izzan which refers to the EN 16019:2014 standard with Light rail loading referring to ASME RT-1-2010. By using this loading, a manual calculation of the longitudinal Force that occurs in the Light rail model is carried out where this longitudinal Force will be the input Force for the Automatic Coupler to carry out the coupling process. After calculating the load, trajectory analysis is carried out to determine whether the Coupler can carry out the coupling process. Dimensional Synthesis is used to obtain changes in the position of the link and joint Coupler when carrying out the coupling process. Numerical simulations were carried out to determine the bond strength.
From the results of research that has been done, it was found that the strong bond of the Coupler occurs when the Coupled hooked plate and coupling link Positions form a parallelogram formation. Dimensional Synthesis generates the geometry and positional boundaries of the movement of the Coupler components. The results of the Static simulation using AISI 1045 material, it increases the strength with the resultant force ∑▒〖F=0〗 and increases resultan 6,9 N. There was a decrease in stress due to the tensile load on the hooked plate from 1183 Mpa to 810 Mpa. There is an increase in stress in compression loading from 480 Mpa to 577 Mpa with the maximum stress on the hooked plate.
