Abstract

Perturbation in a system is one of the troublesome matters in dynamics, vibration, and control. It is not only changing the system behavior but also possibly causing a mechanical failure. This paper presents the effect of perturbations on the decay curve of a damped vibration system. The perturbations are varied from single to multiple forces to give novel knowledge completing previous studies. Additionally, the system properties i.e. damping and stiffness are also varied to provide more meaningful comprehensive information and, thus, can be used in further vibrational system developments. The result shows that the multiplication of perturbation force significantly changes the decay curve slope with unique characteristics. The variation of damping and stiffness also affects not only the vibration amplitude but also the system resonance.

Abstract

Pengembangan peredam model bangunan dengan mengombinasikan tuned mass damper pendulum pounding dan arus eddy. Penempatan pelat konduktor dan massa pendulum magnet sedemikian sehingga dapat menimbulkan efek pounding dan arus eddy. Pengukuran getaran kondisi tunak pada model plafonnya. Respons getaran memperhatikan amplitudo dan root mean square. Pengujian menunjukkan respons model bangunan semakin rendah pada magnet dengan kondisi grade yang semakin tinggi dan posisi pelat yang semakin rendah atau nilai ukurannya yang semakin besar. Studi lebih lanjut pada karakteristik getaran sistem dengan tipe peredam ini dalam domain frekuensi.

Abstract

Penelitian ini mengombinasikan tuned mass damper jenis silinder gelinding dengan peredam dari efek arus eddy pada sistem getaran model bangunan. Silinder berupa magnet yang bergerak pada lintasan tertentu. Pelat tembaga diletakkan di samping lintasan tersebut. Diameter magnet dan radius lintasan divariasikan. Amplitudo respons ditinjau dari olahan data akselerometer ke  oscilloscope. Hasilnya diperoleh bahwa diameter magnet dan radius lintasan yang semakin besar maka amplitudo yang dihasilkan semakin kecil. Studi lebih lanjut dapat dilakukan dengan memperhatikan karakteristik getaran dalam domain frekuensi.

Abstract

Penelitian ini menggabungkan peredam arus eddy dengan tuned mass damper/TMD pada model bangunan. Massa TMD berupa massa magnet silinder gelinding pada lintasan lengkung. Arus eddy ditambahkan dengan menempatkan pelat tembaga di samping lintasan tersebut. Grade magnet divariasikan. Tinjauan dilakukan pada settling time model bangunan dengan menggunakan stopwatch. Grade magnet semakin tinggi menghasilkan settling time yang semakin cepat. Grade magnet yang semakin tinggi menyebabkan redaman arus eddy semakin besar. Studi berikutnya dapat memperhatikan parameter magnet, lintasan, dan eksitasi terhadap respons peralihan dan respons domain frekuensi.

Abstract

The need for electrical energy is very high, but fossil power plants are running low. Consequently, innovations in alternative energy sources are increasing, including sea waves. The geographical location of Indonesia, which is a country with several islands and is accompanied by several beaches, has the potential to bring up innovations in alternative renewable energy, namely wave power plants. In Indonesia, several regions have used sea wave power plants with the OWC (Oscillating Water Column) system. Therefore, this study conducted an experimental OWC test of a piston and turbin as combination mechanism in a water wave power plant by combining the number of pistons and turbines in 3 variations, i.e., 1 piston with 2 turbines, 1 piston with 1 turbine, and 2 pistons with 1 turbine. This experiment compared the effects of the combination of the number of pistons and turbines on the torque, voltage rotation, mechanical power, electrical power, and efficiency of the three combinations. The research results indicated that the combination of 1 piston and 1 turbine produced the highest torque of 4.73 Nm, while the combination of 1 piston and 2 turbines yielded 0.76 Nm, and 2 pistons and 1 turbine generated 4.47 Nm. Out of the three combinations, the highest electrical and mechanical power occurred in the combination of 1 piston and 1 turbine at 8 watts and 298.4 joules per second, respectively, with a voltage of 0.89663 volts, a rotation of 603 rpm, and an efficiency of 10%.

Abstract

Renewable energy is energy that comes from natural resources that are continuously available. Renewable energy will replace fossil fuels that will slowly run out, fossil fuels such as oil, gas and coal. Dependence on fossil fuels results in the depletion of reserves of these energy sources. One of them is a hydroelectric power plant using a Pelton turbine. The working principle of a Pelton turbine is to utilize fluid and water power to generate shaft power. The rotation of the turbine shaft will be converted by the generator into electrical power. In this study, an experiment was conducted on a piston mechanism hydroelectric power plant using a Pelton Turbine with 14 blades with variations in blade angles of 0ᵒ, 10ᵒ, and 15ᵒ with a piston mechanism. The research sought was torque, shaft rotation, mechanical power, voltage, voltage power, turbine power and efficiency. The results of this study show the effect of blade angle variations on the torque produced by the Pelton turbine at an angle of 0ᵒ producing the highest rotational torque of 17.66 Nm, while at an angle of 15ᵒ producing a rotational torque of 17.06 Nm, and the power produced by the Pelton turbine at an angle of 15ᵒ producing higher mechanical power and turbine power compared to angles of 0ᵒ and 10ᵒ, namely mechanical power of 1076.724 J/s and turbine power of 83 watts, shaft rotation of 603 Rpm, and turbine efficiency at an angle of 15ᵒ producing a value of 63%.
