TL;DR: In this paper, an evaluation of a low-frequency vibration calibrator is presented, based on the results of simulation and testing, it is known that there are differences in the output frequency between control components and mechanics.
Abstract: In 2017, the Research Center for Metrology developed a low-frequency vibration calibrator. This calibration system is composed of mechanical and control components. The mechanical component consists of a DC motor and vibration table, and the control component consists of a microprocessor. The type of control used is open-loop control. In this paper, an evaluation of the calibration system is presented. The method used to evaluate is to use system simulation and testing. The tested frequency is 0.5-10 Hz. Based on the results of simulation and testing, it is known that there are differences in the output frequency between control components and mechanics.
