Abstract

The shaft is one component of a motorcycle that is no less important than other components. These components function to support the load of the vehicle itself as well as external loads such as humans or cargo on a motorcycle. This study aims to determine the working stress and also the safety factor on the shaft. The component that will be discussed is the front axle of the Supra X 125 Helm In motorcycle. The method used is an experimental method with qualitative and quantitative analysis. The results of the analysis show that if a load of 70 kg is given, then the value of the working stress is 230.45 N/mm2, while the safety factor is 1.488

Abstract

Beam splicing using butt joints is one of the most common forms of connection found in the construction of bridges, towers or other structures. The size of the connection used is adjusted to the ability of the base material, the existing external load and the material of the seam and rivet itself. The number of rivets used must also be adjusted to the load to be supported. If the number of rivets used is too much, it will also cause stress on the connection itself. Due to the complicated combination of the two elements, namely the seam and the diameter of the rivet used, everyone can determine the size at will regardless of the stress propagation on the seam or rivet. In this study, the authors analyzed the effect of the combination of hole diameter and the distance between holes on the strength of the connection at stack connection. Based on the results of research that has been carried out on a double blade seam plate with variations in the thickness of the seam and the diameter of the rivet. The maximum stress that occurs on the seam or rivet is smaller than the stress on the main plate. So the possibility of failure is greater on the main plate. For rivets with a diameter of 12 mm and a seam thickness of 6 mm, the maximum stress that occurs is still below the main plate stress. At the rivet diameter of 16 mm, the stress began to increase sharply on the main plate and the seam. The decrease in the cross- sectional area due to the increase in the diameter of the rivet increases the stress generation. For connection and rivet safety factors, the average is above 7 and the condition is very safe. This safety factor is also greatly influenced by the distance between the holes and the thickness of the seam plate used. The greater the decrease in the normal surface area, the lower the safety factor.

Abstract

Welding is commonly used in manufacturing, one of the processes in welding is the cooling process. The cooling process is carried out against the results of welding steel ST 37 using air, water and oil cooling media. This process aims to fixing the tensile strength value of the welding result ST 37, without changing the composition chemistry. This process includes welding and cooling at a certain speed to obtain the desired properties as well as varying tensile strength values With experimental research methods, the purpose of this study is to find out how the influence of variations in cooling media on the tensile strength of ST37 steel. From some of the cooling media used, it can be seen that a good cooling media is an oil cooling medium, because the average tensile strength is 53,415 kg / mm2. As for the cooling media what produces the greatest tensile strength is the air conditioning media with the average tensile test was 49,764 kg/mm2.

Abstract

ASTM A106 pipe is a type of low carbon steel pipe used for high temperature applications (up to a temperature of 750 degrees F). This type of pipe is resistant to corrosion and can withstand high fluid pressure, so it is often used in the industrial world to convey water, oil and other oils. The purpose of this study was to compare the heat input resulting from variations in welding current to the hydotest, microstructure and tensile test. The method used uses Gas Tungsten Arc Welding (GTAW) welding with current variations of 70 A, 90 A and 110 A with a Hydrostatic Test pressure of 450 Psi. The results showed that the greatest heat input occurred at a current variation of 110 A with a heat input of 1,349.05 J/mm and the lowest heat input occurred at a welding current of 70A of 1,229.72 J/mm. The results of the microstructure test with variations in GTAW welding currents formed the Ferrite-Pearlite phase as a constituent of the microstructure. The results of the tensile test on A106 steel pipe with variations in welding currents of 70A, 90A, and 110A, the highest tensile strength occurred at a welding current of 110A with a tensile strength of 46.7 N/mm and the lowest tensile strength at a current of 70A with a tensile strength of 43.85. Whereas for the Hydrostatic test with class # 150, the pressure is 1.5x design, so the maximum pressure reaches 450 Psi is carried out on 3 pipes with GTAW welding variation 3 with welding currents of 70A, 90A and 110A, declared successful because no leaks occurred during the test.

Abstract

The front wheels are used to hold the load and maintain the balance of the vehicle while walking. The front axle must be of sufficient dimensions to support the loads imposed on it. This design aims to make an axle using the appropriate material so that it is safe to use, then the method used is to measure directly on the vehicle taking into account the specifications of the vehicle and also the specifications of the axle. The material used to design the wheel axle with bending load is S45C construction steel with a tensile strength of 490-550 MPa. The shaft that receives the bending load produces a stress that occurs due to the shaft of 105 MPa and a permissible diameter of 57 mm while the safety factor that occurs in the calculation of the front axle is 4.2, an element of the machine will be SAFE, if: Material Strength > Occurring Stress. From the calculation results it is also known that the deflection that occurs on the shaft is 7.7 mm.

Abstract

In this modern era, technology is developing very rapidly, so that higher education programs are developed as maintenance, research and development centers. The task of machine elements is a good exercise for students so they can apply the knowledge they have acquired in the form of an analysis of an equipment. Compressor engines generally use electric motors, gasoline engines, or diesel engines as their driving force. The compressor also transmits power from one shaft to another through pulleys that rotate at the same or different speeds which is transmitted through a V-belt that is wound on the compressor pulley which will move back and forth on the piston/piston. For example, a compressor in a workshop is used to fill air in car or motorcycle tires. Compressors are also used to clean dirty engine parts and other benefits that are often encountered daily.
