Abstract

Coupler adalah peralatan perangkai yang menghubungkan antar sarana yg konstruksinya dapat terpisah atau dalam satu kesatuan. Komponen kereta api seperti sistem bogie termasuk coupler, dan konstruksi gerbong yang terlalu berat berdampak pada penurunan performa kereta api. Penilitian ini bertujuan untuk mengurangi berat coupler tanpa mengurangi kekuatan strukturnya. Pendekatan yang digunakan pada desain dan analisa coupler ini yaitu dengan megkombinasikan teknik Generative Design, Conventional Design dan Finite Element Analysis. Objektif yang digunakan adalah meminimalkan berat dengan safety factor minimum yang di tentukan. Variasi luaran CAD model dari gerative design yang dipilih kemudian di evalusai menggunakan Finite Element Analysis untuk melihat failure regions dan less critical regions. Teknik Conventional Design digunakan untuk memodifikasi desain coupler berdasarkan hasil analisa kemudian di evaluasi lagi menggunakan Finite Element Analysis hingga memenuhi objektif yang ingin dicapai. Dari hasil penelitian didapatkan desain coupler dengan berat 85.5% dari berat desain awal, tanpa mengurangi kekutan strukturnya yang di tunjukan dari hasil Finite Element Analysis yaitu tegangan maksimal pada beban tarik sebesar 511 Mpa dan 474 Mpa pada beban tekan.

Abstract

The wrapping up and portray fabricating handle may be a organize of venture work at PT. Lintech Duta Pratama. Disgraceful portray forms result in absconds. Items that have absconds require repair so they can at that point be sent to clients. Rehashed repair forms cause expanded handle costs and obstruct item conveyance. In this manner, to get great item quality and diminish handle costs, inquire about to obtain ideal parameter settings is required. The method parameters considered are surface harshness, substrate temperature, and sort of abrasive fabric. The experimental design used is the taguchi method in the form of an orthogonal matrix . From the exploratory comes about, the ideal combination of handle parameters for prepare costs was gotten, to be specific surface harshness at level 1 with a esteem of 50 μm, temperature at level 2 with a esteem of 34 ° C, and rough fabric sort at level 2 with steel coarseness.

Abstract

This research aims to obtain optimal value for the surface roughness of the material AISI P20 on the Electrical Discharge Machining (EDM) Sinking process. In the present research, the Taguchi method is used to investigate the significant influence of process variables on the machining performance and determine the combination of process variables on the EDM process. Orthogonal array L18 (21 × 33) based on the Taguchi method is chosen for the design of experiment. The experiment is replicated twice to finding out the influence of four process variables such as type of electrode, voltage gap, on-time, and off-time on the response performance. Machining performance is evaluated by surface roughness as a response variable that had quality characteristics, smaller is better. These experimental data were analyzed using the Signal-to-noise ratio and Analysis of Variance. The analysis results show that the surface roughness is influenced by the type of electrode and on time. Combination of process variables to obtain optimal surface roughness are using graphite electrodes, and setting values of gap voltage 40 volt, on-time 250 μs, and off-time 20 μs. This combination of process variables can be applied to the manufacturing process using EDM sinking in order to produce a good quality product that determined based on the surface roughness value.
