Penelitian ini dilakukan untuk mengetahui karakteristik dinamik Computer Numerical Control Router 4 Axis dengan menggunakan metode Bump Test. Pengujian dilakukan dengan cara menempatkan sensor Accelerometer Khoctek 107b pada Mesin CNC Router 4 Axis pada sumbu x, y, z dikerangka atas, kerangka bawah, dan spindle. Hasil eksperimen pengujian getaran Mesin CNC dibagi kedalam dua proses pengujian yaitu kondisi normal dan kondisi rusak pada masing-masing sumbu. Diperoleh bahwa pengujian ini menghasilkan frekuensi global dimana frekuensi 8 Hz, 24 Hz, dan 40 Hz muncul disetiap sumbu x, y, dan z pada kerangka atas, kerangka bawah dan spindle. Pada mesin dengan kondisi rusak muncul frekuensi lokal pada sumbu y kerangka atas sebesar 5 Hz. Kemudian pada sumbu y spindle muncul frekuensi lokal sebesar 10 Hz, 56 Hz, dan 88 Hz. Munculnya frekuensi lokal menandakan adanya kerusakan pada CNC oleh sumbu tertentu selain frekuensi global.

Gasoline engines should sound soft, even tend to be minimal. But when the symptom of a rough sound emerged from the engine room, it was even more like a diesel sound that was quite loud. So that many customers have complained about the rough sound of their vehicle's engine when the engine is started, from the results of the initial inspection that was carried out as a result of the rough noise coming from the bearings on the alternator which experienced wear due to reduced lubrication in the bearings. This requires that preventive maintenance checks on the alternator are a must in the automotive world. On the basis of the above, in this paper, we will discuss the damage to the Daihatsu Luxio alternator with the frequency response function (FRF) method. Damage to the alternator can be seen at point A and point D, seen with a frequency at 1500 Hz in a damaged condition, while in good condition there is no frequency at 1500 Hz. At points B, C, E, and F have the same vibration pattern between the damaged and undamaged conditions. Visually checking results show that the bearing component at point A, it is known that the ball bearing is peeling. This results in a rough spinning of the bearing and makes the alternator make a rough noise while working.

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.
