Abstract

Two kinds of stresses in the gear teeth are root bending stress and tooth contact stress. These two stresses results in the failure of gear  teeth.  The root bending stress results in fatigue failure and contact stress results in pitting failure at the contact surface. The stress analysis used to minimize gear  failure in the  design of helical gear.  It is also optimize the  design of helical gear  on the transmission system of the truck motor vehicle, where the power transmission is required at heavy loads  with  smoother  and  noiseless operation.  In this  paper  bending  stress  and  contact  stress estimated  using analytical method while modeling of gears used the numerical solution. Method of beam strength  based on modified Lewis calculation used to predict the bending strength  of helical gears. Contact stress was estimated  using related method of AGMA contact stress. Stress modeling of helical gears is done by ANSYS 14.5, which is a finite element analysis package. The results are then compared with both AGMA and ANSYS procedures. The values of bending strength and contact stress determined using AGMA method found to be compatible with ANSYS simulation.

Abstract

Pelton turbine have been used for harvesting renewable energy by extracting kineticenergy of water into mechanical energy for more than 100 years. This characteristic makes thissystem remains potential to achieve Goals #12 SDGs. During the operation, the performance ofPelton Turbine is affected by several parameters: hydraulic power, water flow rate, bucketdesign, and nozzle. Among others, nozzle design is the most challenging since this part isresponsible to drive the water direction strike the buckets, converting impulse. The performanceof existing 1 kW Pelton Turbine equipped with 15mm Spear Nozzle is believed can be improvedby varying the nozzle diameter by using low-cost CFD simulation procedure. Ansys Fluent fromAnsys Student 2021 R1 is used in this research. Represented by two-buckets facing spear nozzle,three dimensional CFD simulation is conducted. The nozzle diameter is varied to 15 mm, 14 mm,and 13 mm from two configurations. The first and second configuration is done with water flowrate 3,3 kg/s and 1,3 kg/s respectively. The results show that 15 mm nozzle diameter can producehigher power as high as 594,08 Watt with the first configuration. Even though at the secondconfiguration this 15mm nozzle diameter did not produce the highest power, other parameterssuch as splashing water and erosion effect still show that the 15mm nozzle diameter performedbetter than others. This simulation results also consistent with experimental results whichperformed by using first configuration and 15mm nozzle diameter. The results also show that thesistem performance is much higher at higher water flow rates. Therefore, the development of thesystem can be continued to by using spear nozzle with diameter higher than 15mm.

Abstract

Biodiesel has become an important source as a subtitution fuel for diesel engines. As an alternative fuel for diesel engines, it is becoming increasingly important due to diminishing fossil fuel reserves and the environment consequeness of exhaust gases from petroleum fuelled engines therefore, it needs to be further investigated how biodiesel blend percentage could affect the performance and emission of diesel engine. Waste cooking oil (WCO) is one of the raw material for Biodiesel. WCO that has been converted into biodiesel is made using esterification and transesterification methods. Then, biodiesel is mixed until it has the composition of B20, B30 and B50. The mixture is then tested for performance and emissions. In testing, B30 did not have a significant decrease in performance but the emission test results (opacity) were higher than B20. B50 has a significant decrease in performance when compared to B20, but has the lowest opacity test results.

Abstract

Friction stir welding (FSW) is a solid-state welding method that is very simple, cheap, and in principle only requires equipment to rotate the tool and move the workpiece translationally. In this research, it was demonstrated that the FSW process of aluminum alloy 6061 and high-density polyethylene (HDPE) polymer is possible using a vertical milling machine, however, modifications need to be made to make it possible to regulate the pressure applied by the milling machine through the tool shoulder to the surface of the workpiece. Apart from that, it was also known that for each material undergoing the FSW process, it is necessary to determine the right parameter set which is a combination of rotational speed and tool feed speed to obtain optimal welding results. Too high a tool rotation speed can cause high lifting forces which can produce large porosity in the workpiece. For the HDPE FSW process, too high a tool rotation speed, which is not balanced with the increase in feed speed will provide excessive heat, causing depressions on the surface of the nugget zone.

Abstract

This research aims to provide a detailed guideline for the replacement process of superheater tubes in the Takuma Boiler N-900 R. The superheater tube is a critical component in a boiler that increases the temperature of the steam exiting the boiler to achieve higher temperatures. Superheaters have been utilized since the early 20th century, coinciding with the initial use of steam engines. The research employed direct observation to analyze the causes of failure in the superheater tubes. The primary objective is to present the necessary processes and steps for replacing superheater tubes. The findings indicate that the primary cause of failure in the superheater tubes is overheating, necessitating their replacement. The replacement process involves several stages, including disassembling old superheater tubes, installing new ones, and testing hydrostatic and steam. The results of this replacement process show improved efficiency in the superheater and prevention of further failures in the superheater tubes.

Abstract

The research is motivated by the issue faced by motorcycle users, namely the wear and tear of brake shoes, which can reduce braking effectiveness and increase the risk of accidents. The main objective of this study is to analyze the structural properties of motorcycle brake shoes with three different materials (aluminum alloy, cast iron, and magnesium alloy) and brake linings made of different carbon variants (alumina-carbon composite, carbon ceramics, and carbon fiber) under static pressures. Additional design aspects including weight and production cost are also evaluated during the material selection process for the motorcycle’s brake shoe and brake lining. The 3D modeling of the brake shoe and lining was done in Solidworks using measurement data from a Coordinate Measuring Machine (CMM). The finite element analysis was performed using ABAQUS software. Considering the results from the finite element analysis, weight, and economic aspects, the study found that aluminum alloy (Al alloy) and carbon composite can be suitable materials for brake shoes and brake lining. The Al alloy brake shoe provides 62.7% weight saving while exhibiting good structural properties under static load and a moderate increase in production cost compared to cast iron. Similarly, brake lining with alumina-carbon composite showed the least deformation under static load while maintaining modest production costs compared to the other carbon variants.

Abstract

The simulation analysis approach aims to conduct CFD (Computational Fluid Dynamics) simulation analysis on bushings with different groove shapes in an effort to improve lubrication efficiency. This study is basically a 3D modeling approach and then uses Computational Fluid Dynamics simulation which is a method used to model, analyze, and related phenomena in a system with a numerical approach. The addition of grooves to the bushing surface can affect the flow of lubricant around it. Through CFD simulation, the author will compare the performance of various groove designs to identify models that provide better lubrication. The results of this study are expected to provide valuable insights into the development of more lubricating efficient bushings.
