Abstract

The vibration measurement technology, currently in high demand, utilizes measuring instruments or sensors.
This advanced technology provides high accuracy and is well-suited for applications requiring precise vibration measurements. In engineering, certain types of vibration measurement tasks may not necessarily demand high precision, such as measuring vibrations in structures or other systems with high safety margins. Utilizing sensor fusion technology for vibration measurements is an effective alternative that reduces the need for various resources. In this research,
the development of vibration measurement technology using sensor fusion was studied and compared with accelerometer-based measurement devices in laboratory testing and motor testing at 1,010 ± 15 revolutions per minute for controlled vibration generation. Various masses were added to the motor with a disc, namely 6.735 kg
(0 g), 7.135 kg (400 g), 7.535 kg (800 g), 7.935 kg (1,200 g), 8.335 kg (1,600 g), and 8.735 kg (2,000 g). Each test was conducted 30 times. The experimental results indicated that the natural frequency ranged from 5.12 to 5.27 Hertz. The maximum percentage deviation between sensor fusion and accelerometer-based measurement devices was 1.68%, 1.65%, 1.74%, 1.98%, 2.14%, and 1.52%, respectively. Furthermore, from the vibration measurement test using the sensor fusion system compared with the accelerometer-based measurement device, the maximum acceptable percentage deviation was found to be within 5%.
