ABSTRACT                Today, Society needs a vehicle a simple , inexpensive and environmentally friendly. One alternative option is an electric gokart. In the electric gokart are a rear axle which serves to move the power and spin that comes from the electric motor to the rear wheels so as to allow an electric go-karts can run. The aim of this study as follows : First, create a simulation of the finite element method with SolidWorks software to get the voltage and the maximum deflection caused by the load . Second, making calculations manually finite element method to validate the simulation results with SolidWorks software. Third , get the dimensions of the shaft for electric gokart designed by the Department of Mechanical Engineering University of Samratulangi Manado.                Finite element method simulations with SolidWorks software has gained maximum voltage results 120,212x106 Pa., and the maximum deflection of 0.00051 mm. While the manual calculation values ​​obtained displacement / maximum displacement is 0.00045 mm. Besides the results also indicate that the maximum displacement occurs at the same location or point. Thus , the simulation results have been validated by using the results of manual calculations. The dimensions of the design is the diameter of the shaft 20 mm and a length of 1000 mm.   Key word: Gokart, Finite Element Method, Simulation.

Abstract

The aim of this study is to analyze the strength of the shaft of the landing gear aircraft N-219 against the variation of cargo’s weight. The examined object in this study is the landing gear of N-219 aircraft produced by PT Dirgantara Indonesia. The static strength analysis was conducted on the stress and maximum deflection to the shaft of the landing gear N-219 aircraft. The results of this study showed that the variation of cargo’s weight affects the strength of the landing gear shaft where the increase of the cargo’s weight will result in a linear increase of deflection and stress. Finally, the allowed maximum weight of the N-219 aircraft cargo is 2500 kg with the landing gear shaft deflection of 0,00164 meter and the stress of 298 MPa. Simulation in this study was conducted by using ANSYS 2014, where this software provides load, deflection and stress analysis. It is found that the analysis of manual calculation and software-based calculation shows only little difference.   Keywords : Aircraft N-219, Landing Gear, Shaft, Strenght analyze

Abstract

ABSTRACT A pressure vessel is a container for a pressurized fluid, both liquid or gas. The stress on the shell of pressure vessel must have serious attention because the stress is the basic in determining the dimension and the type of material used, and also the treatment for the pressure vessel. This research intended to obtain the maximum stress in the pressure vessel 13ZL100040291 of the working pressure. The object of this research was a vertical type cryogenic pressure vessel at PT. Aneka Gas Industri, sagrat, Bitung. The analysis was conducted by applying the finite element method aided by softwares. Research results showed that the maximum stress at the inner vessel based on the software simulation is 203,79 MPa, with nominal stress of 33.965 MPa. The nominal stress based on the calculation using mechanical theory is 37,24 MPa. The stress calculation in simulation using software had considered the stress concentration. Afterwards, based on the simulation results, it was found that the stress concentration at the inner vessel and outer vessel is 6. The maximum stress calculated by the simulation software at inner vessel and outer vessel is stell in the safe limit, because the Von Mises stress is smaller than the allowed stress of each material used.

Abstract

A gear is one of the important elements for transferring motion (especially rotation) and power or energy in a transmission system between the driver and the object to be driven. Gear manufacturing is quite complicated and complex with a variety of size and accuracy depends on the role of the gear itself in a machine. The use of speadsheet application provides advantages for designers where the design process becomes easier. Spreadsheet is an interactive computer application program to organize and analize data in tables. This paper presents an application of spreaddsheet that has been made for designing a spur gear.

Abstract

Nowdays, the industry plays a vital role in the economy; therefore design of an efficient plant industry is very important. There is a component for handling a pressurized fluid, such as a pressure vessel. The purpose of this study was to determine the maximum deflection occurs at a vertical pressure vessel due to wind loads, and obtains maximum height of pressure vessels based on the allowable deflection. The object of this research is in Bitung. Bitung is one of the industrial cities located in the Province of North Sulawesi. Wind velocity was obtained from BMKG Bitung Maritime Station. Analysis of deflection applied to pressure vessel which has height of 25 ft to 150 ft. The results showed that the higher the pressure vessel, the higher the deflection. The maximum deflections for height of 25 ft to 150 ft have been determined. Furthermore, based on allowable deflection, the allowable height of the pressure vessel in Sagerat Village-Bitung City is 147.44 ft. Keywords         : Wind Load, Pressure Vessel, Deflection, Bitung

Abstract

Axle Shaft or wheel driver shaft is a component of a vehicle that intended to continue the rotation of the differential to the wheels. The purpose of this research is to get the distribution of life, damage, and safety factor on the axle shaft due to fatigue load using Ansys 14 software, and to know the location at the axle shaft that potentially damaged due to fatigue load.            At first, literature study was undertaken, then did data colecction. After that, developed model of Axle Shaft using SolidWorks 2013. Finally, did fatigue analysis with software Ansys Workbench 2014. Based on the analysis, obtained life time, damage, and safety factor at Axle Shaft. In addition, also did macroscopic observations at surface of a broken Axle Shaft.            Distribution value of life time, safety factor, and damage due to fatigue loads have been obtained. On the other hand, the location at axle shaft that most potentially damaged is about 3.3 cm from the left end. Based on the macroscopic observation, the damaged at Axle Shaft cause by torsion occurring at the shaft. Keyword: Fatigue, Axle Shaft, Simulation
