Abstract

The objective of this research is to analyze the results of the topology optimization model Hip Stem Prosthesis in heel strike and flat foot conditions. The simulation is done using software based on finite element method ANSYS Release 18.0. Analysis of heel strike and flat foot conditions was carried out on the design of the artificial pelvic bone AML (Anatomical Modullary Locking) model. The ball head diameter used in this research was 38 mm and stem length was 140 mm. The analysis is done by optimizing the hip stem prosthesis step by step according to the condition when walking. Loading is given to the hip stem prosthesis during heel strike and flat foot with a time history of 0,01 seconds and 0,2 seconds starting from the initial position of heel strike and ending with the flat foot position. The simulation results show that the stress distribution is evenly distributed and the size of the volume of the design region varies.

Abstract

Wind energy is one of the energy that is starting to be used to produce electricity or convert it to mechanical energy for other purposes. One of the tools used to harness wind energy is a wind turbine. Indonesia, especially Aceh, is one of the countries that has not used wind energy as a power plant because of the characteristics of wind in Indonesia which tends to be low-speed. Archimedes spiral wind turbine is a new type of wind turbine that can operate at low wind speeds, consisting of two to three Circular blades form an axis, then wrapped around each other and one side is extended, the design of this turbine essentially mimics the shell of the Nautilus snail (Biomimicry). The basic principle of this wind turbine is designed using the legal principle of Archimedes. This scientific work will analyze the effect of variations in the number of blades on rotation and the influence of blade rotation on wind speed using the experimental method, therefore turbines are made with variations of 2 blades and 3 blades, and the outer diameter is 80 cm and overall length is 90 cm. From the results of the study it was found that the 3 blade wind turbine has a better percentage of shaft rotation compared to the 2 blade wind turbine that is equal to 16.67%. Maximum wind power occurs on the 4th floor with a value of 164.3 watts

Abstract

This paper discusses the stress analysis of marine boil off gas pipe elbow. The piping system receives several loading conditions such as expansion load, occasional load, operation load, and sustain load, which are referred to as static loading conditions. As a result of the load conditions can be known stress distribution and examine the strength of the weld connection on the pipe elbow. The purpose of this research is to know the distribution of stress at the elbow of the pipe due to static loading conditions. The method used in this study using finite element analysis. The result of stress simulation in pipe elbow is 771 Pa and the result of calculation of stress in pipe elbow is 3,94 Pa. The result of piping system simulation shows the value of the pipe elbow e due to the load operation of 23151,34 kPa, the sustain load is 24918,91 kPa, the occasional load is 59110,83 and the expansion load does not produce the stress value. From the results of the analysis, the stress due to operating, sustain, and expansion loads are categorized as safe because they do not exceed the allowable stress values of each loading condition.

Abstract

The function of solar collector is to increase the air that consist of absorber, air duct and glass cover. One of the factors that affect the collector output temperature increased is depend on high temperature absorber. An absorber serves to absorb heat from the sun, and heats flowing air in the air duct above the absorber. The heating of the air pass/route is greatly influenced by the flow patterns inside the collector. In this study the authors examined the use of variations absorber on solar collector. There were four variations of The absorber; iron sand, gram iron sand, asphalt hotmix, and iron sand asphalt. The research method is intended to determine the value of heat transfer by radiation, conduction and convection. Dimension of solar collector was used 300 cm x 80 cm. The best variation of absorber was gram iron sand type at the most optimum intensity of sun at 12 a.m-2 p.m.

Abstract

Composite material is a combination of two or more different materials between resin and fiber. The characteristic of this material is that it has a high level of corrosion resistance. This study aims to analyze the strength and durability of jaloe kayoh made from Jute fiber polyster composite materials. Dynamic analysis on jaloe kayoh is done through simulation or modeling using CAE-based software with the Finite Element Method (FEM), using dynamic-implicit conditions. The parameters examined include stress, strain and displacement values for uniform loading on the entire boat body with a minimum load of 600 N and a maximum load of 3000 N accompanied by amplitude. Variations in material applied to the jaloe kayoh include jute, jute glass, jute glass jute, and fiberglass. From the simulation results on the loading of 3000 N the largest maximum stress obtained by jute glass jute material with a value of 1,707×106 Pa, the largest maximum strain by jute material with a value of 2,721×10-5, and the largest maximum displacement by jute material with a value of 1,400×10-5 m. Then the results of the study showed that the four composite materials were categorized as good to be applied as the main materials for the body of the jaloe kayoh.
