“…Penelitian mengenai getaran telah lama dilakukan di universitas mercubuana terutama dengan menggunakan FFT analyser, seperti Identifikasi pada nonlinear dengan menggunakan metoda FRF, selanjutnya dilakukan analisis dengan menggunakan wavelet packet decompotion (Subekti et al,2018). Subekti (2018) (Subekti et al, 2019). Karakteristik getaran screw compressor pada berbagai kondisi putaran dapat screw comporesor mengalami unbalance, hal ini dikarenakan munculnya amplitudo pada 1x RPM selain itu mengalami ketidak lurusan dikarenakan mengasilan getaran yang lebih besar dari keadaan normal 2 x RPM (Sangian et al, 2020).…”

Pertumbuhan permintaan listrik akan menjadi sangat kuat di negara berkembang. Kebijakan pemerintah, kondisi pasar, dan teknologi yang tersedia secara kolektif menetapkan arah pasokan listrik untuk beralih ke sumber rendah karbon, dengan pangsanya meningkat dari 36% saat ini menjadi 52% pada tahun 2040 dalam Skenario Kebijakan yang Ditetapkan. Hal ini perlu diperhatikan untuk meningkatkan sumber energi baru terbarukan. Salah satu energi baru terbarukan yang dilakukan di universitas mercubauan adalah memanfaatkan aliran pipa. Pada instalasi perpipaan juga akan mengalami pembebanan akibat pengaruh dari massa jenis fluida ,tekanan, aliran fluida dan massa pipa itu sendiri. Hal hal tersebut akan menimbulkan getaran. Penelitian ini akan membahas tentang eksperimen getaran pada pipa jenis Polli vinil klorida (PVC), dengan variasi bukaan katup pada sudut 0 o , 30 o , 45 o dan 60 o. Selain pengujian dengan aliran air, akan dilakukan karateristik dinamik dengan mengunakan fungsi respon frekuensi (FRF), pengukuran getaran diukur pada arah sumbu x dan y. Hasil pengukuran getaran menunjukkan bahwa karakteristik dimanik pada sumbu x dan y mempunyai kesamaan karakterik dinamik sutruktur. Sedangkan akibat adanya aliran fluida pada pipa menunjukkan bahwa dengan tekanan air yang semakin besar ferekunsi yang terjadi lebih stabil dibandingan dengan tekanan air dengan pembukaan valve 60 o. Hal yang harus diperhatikan pada turbin propelller ini adalah pemasangan clamp untuk mengurangi noise pada sumbu Y.

“…FRF testing is to determine the dynamic characteristics of a single-cylinder diesel engine [16] and a Sigra disc brake [17] to obtain global and local vibration modes. Also, the bump test method can be performed to determine the damage to the Sigra disc brake [18]. The vibration method is used in the production process to predict end mill damage on CNC machines [19].…”

The alternator or dynamo ampere is a device that functions as a generator that produces alternating current (AC) and converts it to direct current (DC). Signs of damage that often occur due to damage to the Alternator are the smell of burning, squeaking, dim spotlights, indicator lights, malfunction of the battery, and the supply of electricity. These signs will cause the vehicle to stop in the middle of the trip the electricity supply is very lacking. This requires that preventive maintenance checks on the alternator are a must in the automotive world. In this paper we research measuring the vibration of the alternator due to the influence of rotation speed (750 rpm and 1800 rpm), to predict damage to the alternator of the Daihatsu Luxio vehicle. The results of this study indicate that at the rotational speed of 750 rpm and 1800 rpm, were found 1x rpm the condition of the vibration amplitude on the alternator is smaller than the alternator in poor condition, this is due to the presence of an unbalanced alternator. Also, vibration due to misalignment is obtained because it has characteristics, among others: vibrations with a frequency of 1xRPM and/or accompanied by a relatively large 2xRPM, and relatively high vibration in the axial direction.

The air compressor engine is becoming a requirement for both large and small industries production machines instead of the drive system of the driven motor becomes pneumatic. In a pneumatic drive system requires certain air pressures are adjusted to the needs of the industry. Compressor engine which widely used is a screw compressor. On the screw compressor, male and female rotors in the air producer are part of the very important because as the primary producer of compressed air from the motor rotation, then the maintenance must be considered regularly, especially vibrations resulting. The study was conducted to test the amount of vibration that occurs on the screw compressor rotor from the rotor rotation variations using vibration measuring devices FFT analyzer. Measurements are made by attaching the accelerometer sensor to the x, y, and z-axis of the compressor screw rotor casing. Three variations rotors are 2557 rpm, 5042 rpm, and 7508 rpm to get a reference to the magnitude of rotation that is best used in the refrigeration machine is reviewed of the amount of vibration produced. From the results of testing and data collection, it can be concluded that vibration is measured using an FFT analyzer of vibration values the highest is at 7508 rpm which is 7.768 Hz and the lowest is at rotation 2557 rpm of 6,442 Hz. Characteristics of screw compressor vibrations in various rotation conditions can be unbalanced due to the emergence of amplitude at 1x rpm it also experiences a misalignment due to generating vibrations which are higher than usual 2x rpm.
