Establish Measurement System for Vibration Lab Unit Using Arduino

Abstract

As science and technology develop quickly, suitable measurement system is becoming more achievable. In dynamics of structures, measuring vibrations take a serious view during the process of design and construction to avoid resonance. The main objective of this study is to establish a vibration measurement system for a laboratory vibration unit by using a virtual instrumentation system. The Arduino microcontroller is used as the receiver of the electrical signals coming from the displacement sensor, which is connected to the vibration unit. The microcontroller then processes the electrical signals and send it to LabVIEW software on the computer for processing. The established measurement system is able to calculate the vibration of the moving body. Hence, the natural frequency of the system could be determined, and shock absorber for the unit could be designed. Results have been validated using calculated theoretical results of the unit. Thus, the unit is ready to conduct laboratory experiments on the concept of mechanical vibration.
