Abstract

The Savonius Wind Turbine is a drag type vertical axis wind turbine, and it operates by cupping and dragging the wind, causing the rotor to turn and generate electricity. The Savonius Wind Turbine usually has about two or three scoops or cups to catch the wind. The design allows the turbine to rotate relatively slowly, however, there is a high torque yielded from the rotation.On this research, the wind turbine Savonius type-U is designed using Matlab 7.0 with the design process starts from the needs of electrical power 100 watts and 12 volt electrical voltage and wind speed 8 m/s so obtained what is the magnitude and width of the radius of the wind turbineKeywords: wind, turbine, electrical power.

Abstract

In general, kinematics analysis is done using graphics methods. But this method requires a substantial time in analyzing the kinematics of a mechanical system. With the development of technology, especially in the field of computers and informatics can facilitate the engineer in analyzing the kinematics. One method used with the aid of a computer program is the method of complex numbers. This study aims to analyze and compare the position, velocity, and acceleration results of the calculation method of complex numbers and methods of polygon graphics. The study was conducted on a robotic mechanical system, i.e. electric tandem bicycle partner named Robot Joules. Necessary data were analyzed using the method of complex numbers with the help of MATLAB program. Results of analysis using the method of complex numbers were compared with the results of analysis using the method of polygon graphics. For comparison, data input were made equal to the angular velocity rod 2 (ω2) of 10 rad/s and angular acceleration of rod 2 (α2) at 0 rad/s2 when bar 2 was at position angle 90 ° from the positive x-axis. Key words: kinematics, robot joules, complex numbers

Abstract

Struktur silinder (tabung) dapat digunakan untuk sistem transportasi antar pulau, dibangun sebagai terowongan terapung terendam (SFT). Struktur utama SFT adalah tabung berlapis yang digabung dan tali tambat untuk menahan gaya apung. Kajian ini menyajikan hasil stress assessment pada tabung silinder berlapis dengan beban tekanan eksternal dari air laut. Pemodelan dan analisis dilakukan dengan metode elemen hingga menggunakan ANSYS. Tabung terdiri dari tiga lapisan: lapisan terdalam adalah baja setebal 30 mm, lapisan tengah adalah beton setebal 450 mm dan lapisan terluar adalah aluminium setebal 150 mm. Diameter dalam dan luar tabung masing-masing adalah 5 m dan 6,26 m. Beban yang diberikan adalah tekanan internal sebesar 101 kPa (1 atm) dan tekanan eksternal hidrostatis pada kedalaman 500 m sebesar 5,35 MPa. Hasil kajian menunjukkan bahwa hoop stress terbesar terjadi pada lapisan baja, diikuti oleh lapisan aluminium dan lapisan beton. Untuk radial stress yang merupakan tegangan tekan, nilai terbesar terdapat pada lapisan aluminium dan nilai yang lebih kecil terdapat pada lapisan terdalam (baja). Untuk tegangan geser, tegangan pada lapisan baja dan beton jauh lebih kecil dibandingkan dengan tegangan pada lapisan aluminium.

Abstract

As an archipelagic country, Indonesia has great potential for marine resources. This potential must be supported by theoretical studies as the basis for the development of marine technology. For this reason, in this study a laboratory scale wave medium was created as a medium for observing the kinematics of water particles and defining the equations of wave motion. Water particles are represented by buoy balls that are installed at various depth levels. The motion of the buoys is recorded with a video recorder and then converted into a displacement graph with a video tracker application. The wave generator is designed to get a variety of wave sizes and types. The wave generator moves back and forth and is connected to an eccentric rotor by a sliding crank mechanism. The eccentricity of the rotor can be varied, in this study it was determined that e1=3cm, e2=5cm and e3=8cm. From the test results it can be concluded that for e1 the type of wave that occurs is in accordance with the Airy Equation, while for e2 and e3 the waves are obtained in accordance with the Stokes Equation. In addition, it is also known that the displacement of water particle movement is maximum on the surface and decreases at deeper levels.
