Balancing Rotor Dinamik Menggunakan Sinyal Suara

---

Rotating machines that have been operating within a certain period of time there is frequent vibration. The vibration is usually caused by unbalance, misalignment, bearing defect, and others. Unbalance is ranked first cause of vibration, where more than 80% cases of vibration caused by unbalance. This condition causes the balancing process needs to be done. A commonly used method is vibration measurement, using vibration sensors such as accelerometer or vibrometer should be affixed to the machine in operation. This can cause discomfort and may even dangerous the operator when measuring the machines. The solution of the problem can be done using non contact measurement, where the sensor is not attached directly to the test equipment. A microphone is one device that can record the sound signal and its use without having to contact the tested device. The unbalance tendence of the test is characterized by the presence of the dominant frequency at one rotational speed (1 x rpm). From the test, the result of balancing of normal condition on one rotor and two rotor are 0,039 V and 0,031 V with balancing efficiency 87,88% and 80,74% respectively. The addition of unbalance mass on one rotor and two rotor obtained balancing result that is 0,031 V and 5,88x10-3 V with efficiency of balancing respectively 93,58% and 97,43%.
