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

The purpose of this study was to obtain the results of modeling and simulation for H-Darrieus wind turbine with straight blades. There are two approaches used in this study, namely hand calculation and software analysis. The calculation and analysis employed wind speed data of Manado City. Before applying software analysis, the data is processed to obtain the lift & drag forces that occur in turbine blades and other forces acting on wind turbines. Furthermore, the results of hand calculations and software analysis are compared so that the results of modeling and simulation are validated.The average counted-power of turbine is 181,81 watts, the wind turbine diameter is 2260 mm, and the wind turbine height is 2350 mm. The lift force is 143,257 N & the drag force is 3,978 N which is based on the attack angle 8,95, and the maximum Von Mises stress in the wind turbine is 184,96 MPa. Therefore, the wind turbine would not fail because the maximum stress that occurs in the structure is smaller than allowable stress of the material.Finally, the results of the modeling and simulation for the H-Darrieus wind turbine with straight blades are successfully obtained. The output of this research is turbine design drawings.Keywords: Darrieus Wind Turbine, Modelling, Simulation, Lift & Drag Force

Abstract

When the car moves forward, the air flowing through it will be left behind. By placing a wind turbine on a car, the air flow can be used to rotate the turbine. The addition of tunnels and turbines on the car will change the aerodynamic force, so that it will change the amount of power the car needs. To analyze this, modeling and simulation were carried out. The modeling software used is SolidWorks 2013 Premium and the simulation software is Ansys Workbench 18.1. This study uses three car models, namely: conventional car models, cars with front tunnels and cars with rear tunnels. Making tunnels and installing turbines affect the aerodynamic forces. The aerodynamic force of the car after the turbine installed is smaller than the aerodynamic force of the car before the turbine installed for the car mode of rear turbine modification, while for the car model of front turbine modification, the aerodynamic force of the car after the turbine installed is greater than the aerodynamic force of the car after the turbine installed. The dimensions of the Darrieus helical wind turbine are 0.3 m in height, 0.2 mm in diameter, the blade profile uses NACA 0021, and the blade length is 0.03 m with a helical angle of 50º. At a car speed of 100 km/h, it is obtained Cp of 0.55 with a power of 60.2 Watt for the wind turbine installed in the rear tunnel car, while for the wind turbine mounted on the front tunnel car, it obtained Cp of 0.26 with a power of 3.903 Watt.
