Abstract

This paper presents a study of a composite car body using finite element method. The body is made of surface model and the study is conducted to simulate the possible deformation of the body under certain load. The objective is to find tha ideal thickness of the composite body as to minimize the vehicle weight. In this research, the strength analysis using finite elements will be explained and the deformation of the body is investigated for finding a possibility to improve this research.

Abstract

Additive manufacturing (AM) or commonly called 3D printing (3DP) and rapid prototyping (RP) is a  technique of blending materials by either fusion, binding, or solidifying materials. Despite many advantages of AM, there is a drawback  of AM such as the surface quality may not be as good as subtractive machining  (SM) process, therefore it will be better to have the initial shape forming process with AM and then finishing the required surface with SM process within a single setup. This paper presents the preliminary design of hybrid AM-SM machine to process a resin based material. The design includes structural design and control design of the machine using the material and firmware widely available in the market. Keyword: Additive, Subtractive,  Manufacturing,  Hybrid  Machine

Abstract

Excitation system is a system that conducts electric current in the same direction as a generator in a power plant, so that it produces electricity and a large voltage on the increase in the excitation current. In modern regulatory systems, excitation plays an important role in controlling the stability of a development because it involves load fluctuations, so excitation as a controller will require control of the generator output such as voltage, current and power factors in a necessary manner. If the excitation current rises, the reactive power supplied by the system generator will increase otherwise if the reactive power supplied will decrease. If the given excitation current is too small, the reactive power flow will move from the system to the generator so that the generator absorbs the reactive power from the system. This situation is very dangerous because it will cause excessive savings on the stator.Keywords: Generator, excitation system, transformer, rectifier.

Abstract

Valve (valve) as one of the industrial products, is needed by companies engaged in controlling fluid flow for efficiency. This need is widely used by power companies and the oil and gas industry. The purpose of using valves is to limit and control liquids under high pressure conditions. One valve that is often used is the gate valve, which is a valve with a type of motion fully open and fully close. The demand for this gate valve requires a product with certain specifications to have a design with a good level of strength. In other words, a good valve product (valve), must have a good strength, safe and in accordance with the needs to be tested. This study aims to analyze the gate valve 2 9/16 WP 3,000 psi to ensure the valve produced is according to specifications, strong and resistant to fluid pressure. The method used is Finite Element Analysis (FEA) with the 2018 Solidworks software. The analysis is performed on the gate valve with a full open, full closed state and with gradual loading starting at 1,000 psi, 2,000 psi and 3,000 psi resulting from Computational Fluid Dynamics (CFD). The analysis was carried out at 300C, Based on the results of the analysis with FEA, it was stated that the gate valve 2 9/16 WP 3,000 psi was strong and safe to use. The safety factor value is significantly higher than the minimum permissible safety factor value.

Abstract

Screw conveyor is a material transfer equipment that is often used in various types of industries. However, the screw conveyor also has some disadvantages if it used in the blasting room serves to transport the steel grit which is the main material in the blasting process. This screw conveyor often suffers damage to the pillow block due to the inclusion of steel grit. Based on field conditions, the screw conveyor transport capacity is considered inefficient because some of the steel grit left in the gap between the screw and the curved steel plate and not get transported by screw conveyor. In order to overcome the problems, a belt conveyor is chosen to replace the screw conveyor. The method used in this final project firstly is identifying the problem of the existing screw conveyor and observing the screw conveyor data. Secondly, by using the screw conveyor data, the author makes a design of a belt conveyor as the replacement of the existing screw conveyor. As a result, the belt conveyor design has been created with a calculated capacity of 236.81 tons/hour, which is greater than the existing screw conveyor. and is designed not to be easily damaged due to the inclusion of steel grit as it happened in the screw conveyor. Keywords: Screw Conveyor, Belt Conveyor, Steel Grit, Blasting Room, Pillow Block, Capacity, Design

Abstract

This paper presents the analysis of mini excavator excava 50 with a focus on the boom component. The boom component is a component that has a heavy workload. The material used in the existing design is SM490A. The results of the analysis are still not safe because allowable stress is less than working stress. The material in the existing design was replaced with Hardox 400. The design is declared safe. However, the costs of the product have increased because Hardox 400 materials are more expensive than SM490A. To reduce the costs of the product, design improvement is needed to optimize the use of material. The design improvement method that uses in this study is according the optimization method, that is sizing and shape optimization. After improvement the design, to predict how long the boom component can be used, fatigue life prediction is calculated using Goodman’s theory
