- A structure can experience vibration at a certain level, parameters such as material properties, position of supports, and system frequency determine their vibration characteristics. This study aims to analyze the relationship between natural frequency and vibration mode using both Autodesk Inventor software and experimental method. Vibration mode analysis was carried out on 5 modes of a cantilevered aluminum beam. Experimental tests were also carried out to measure the dynamic responses or vertical vibration displacements using a vibration meter. The beam used was 6061 Aluminum series material with a length of 90 cm with 5 measurement points at an interval of 18 cm. The results show that each of natural frequency (wn) has a different vibration mode. The experimental results show the same trend as the simulation results. Thus, the vibration are determined by the frequencies applied to the system and measurement positions on the cantilevered aluminum beam.
