Abstract

Komponen mesin pesawat yang sering mengalami kerusakan adalah turbin yang berbahan dasar nikel. Salah satu solusi untuk mengatasi masalah tersebut adalah mengganti dengan turbin yang baru dengan cara pengelasan. Masalah yang timbul dalam pengelasan ini adalah tidak adanya filler rod pasaran yang cocok untuk bahan dasar superalloy nikel sehingga perlu dilakukan rekayasa filler rod. Pengelasan dengan menggunakan rekayasa filler rod memerlukan pengujian kuat arus agar diketahui kuat arus yang tepat dalam menghasilkan panas untuk mencairkan logam dasar. Penelitian ini bertujuan untuk mengetahui pengaruh kuat arus terhadap kekerasan material superalloy berbasis nikel yang dilakukan pengelasan TIG menggunakan rekayasa filler rod. Kuat arus pada saat pengelasan divariasi sebesar 70 A, 80 A dan 100 A sehingga didapatkan 3 spesimen uji. Masing-masing spesimen diuji kekerasan micro Vickers. Dari hasil pengujian didapatkan bahwa pada daerah las mempunyai nilai kekerasan yang paling tinggi di bandingkan daerah HAZ, daerah logam induk dan daerah logam induk bagian ujung.

Abstract

The standard box car design has a large drag and wake area which results in high fuel consumption. One way to reduce drag and wake area is to modify the box car design. Modifications were made by adding an aerokit spoiler and deflector to a standard box car which is expected to reduce drag and wake areas. The next step is to design a simulation using CFD-based CAD. The analysis was carried out with three variations of speed, namely 60 km/hour, 80 km/hour and 100 km/hour. The simulation results show that the design of the box car with the modification of the addition of aerokit spoilers and deflectors can reduce the drag and wake areas.

Abstract

The problem faced by the PT Ganding Toolsindo company is that it still takes a long time to set the dies on the Seyi SN2-300 Press Machine, this is due to the long process of tightening and releasing the bolts, so it requires a proposed work aid design to shorten the process time for tightening and releasing the bolts. bolt on the die. This research aims to design work aids in the form of a hydraulic system to support die clamping in tightening the dies. The method used in this research is designing tools for the hydraulic system when setting up dies on a press machine. The results obtained by this research are in the form of a hydraulic system design that supports dies clamping during internal press machine setup where this tool can eliminate the operator's work in tightening and releasing bolts during the dies setup process on the Seyi SN2-300 Press Machine at PT Ganding Toolsindo. The design of this hydraulic system is described using CAD software which is based on calculations and dimensions of the dies used in the press machine.
