Abstract

Penelitian kali ini menjelaskan tentang proses carburizing pada baja. Perumusan masalah tentang carburizing dengan variasi waktu tahan 15 menit, 30 menit, 45 menit, 60 menit terhadap kekerasan dan struktur mikro pada baja karbon ST60. Proses pack carburizing banyak digunakan untuk meningkatkan kekerasan permukaan pada baja. Pada penelitian ini ukuran butir karbon yang digunakan adalah mesh 140 (105 µm) dengan temperatur 900°C. Hasil penelitian ini menunjukkan bahwa pada variasi waktu tahan 15 menit nilai kekerasan rata-rata 56,7 HRA. Pada waktu tahan 30 menit rata-rata nilai kekerasannya adalah 57,1 HRA. Lalu pada waktu tahan 45 menit rata-rata nilai kekerasannya adalah 57,4 HRA dan pada waktu tahan 60 menit adalah 57,5. Untuk raw material memiliki rata-rata nilai kekerasan 66,7 HRB. Jadi raw material setelah di carburizing mengalami peningkatan kekerasan sebesar 167-173%. Dengan demikian waktu tahan pada proses pack carburizing mempengaruhi kekerasan material

Abstract

Rubber force is a simple but important thing for vehicles. This component is located in the rear wheel drum which is directly connected to the gear. Many factors influence the damage to this component. This research aims to determine how much influence stearic acid has on the hardness and tensile strength values of the lifting rubber compound. The materials used to make the compound are rubber smoked sheet (RSS) and synthetic rubber mixed with the chemicals stearic acid, black carbon white oil, ZnO, paraffin wax, MBTS, comaron resin and sulfur. These ingredients are mixed using two roll mixing until they combine and form a compound sheet. To determine the maturation time of rubber, a rheometer process is carried out. The next process is vulcanization of rubber using a mold that is pressed at a temperature of 1600C and a pressure of 150 psi. Tensile testing uses rubber testing equipment with SNI ISO 37: 2015 (IDT–2011) standards. Hardness testing uses a tool with a Shore A hardness tester scale with ISO 7619–1:2010 standards. Based on the results of the tests carried out, the addition of sulfur has a very significant effect on the hardness value and tensile strength value. For the hardness value of compound 3 with a sulfur composition of 6 phr, it has the highest hardness, namely 77 Shore A and the lowest value is composition 1 with a hardness value of 65.6 Shore A. The highest tensile strength value is 15,394 N/mm2 in composition 1 and the lowest value is in composition 3 with a value of 11.44 N/mm2

Abstract

A single friction plate clutch is one part of the components in a vehicle that is used to transmit power and rotation from the driveshaft to the driven shaft without slippage. This study aims to compare the results of mathematical calculations with analysis based on finite element methods in the design of a single friction plate clutch such as shaft, spline, friction plate, and spring. The analysis was carried out on the shaft made of S30C, spline made of S30C, friction plates made of steel alloy, and springs made of carbon steel. The component was drawn by Solidworks-17 software and analysed by Abaqus 6.14-5 software based on finite element methods. The study was performed by comparing the sizes of the various elements. A comparison of simulation processes using the stress concept of von-misses was conducted. The results of mathematical calculations with the simulation process were compared, and the maximum deviation was 2.881%. The deviation was considered acceptable. Based on von-misses’ maximum stress, the material was safe to use due to below the yield strength.

Abstract

This research aims to determine the effect of adding a one-tube and two-tube Torque Expansion Chamber (TEC) to the exhaust manifold on motorbike performance. Torque Expansion Chamber includes one tube with one channel and two channels, two tubes with one channel and two channels. Motorbike performance testing includes torque, power and specific fuel consumption (kbbs) using the Dyno Test. Research shows that by adding TEC, variations in the number of tubes and number of channels have an effect on better performance than standard exhaust manifolds. The best torque with the addition of one two-channel tube and two two-channel TEC. Best power with the addition of one two-channel tube and two two-channel TEC. Best fuel consumption with the addition of one tube two channel TEC.

Abstract

The purpose of this study is to develop the piston ring damage detection technique using vibration analysis. Vibration analysis was performed by measuring vibration in four stroke engine which were worn and scratched on its piston ring, then compare it with the vibrations generated by engine which had a good conditions. Tests carried out on engine rotations of 750, 1500, and 2250 rpm, where the sensor were placed on the cylinder head and cylinder block. Vibration measurement produced a signal in the time domain, which then be analysed their signal energy by manual calculation which based on trapezoidal rule. Result of the research showed that the vibration signal energy decrease in all of the strokes of the defect piston ring. It was caused by the pressure of the defect piston ring smaller than the good piston ring. The decrease of vibration signal energy in suction and compression stroke were greater than the power and exhaust stroke. Indication of piston ring defect could be shown from the decrease in the vibration signal energy in all of the strokes.
