Dynamic Response at Various Points of Aluminum Cantilever Beam

Abstract

The aim of the study was to analyze the dynamic response along an aluminum cantilever beam. The data measured were displacement (mm), velocity (mm / s), and acceleration (m/s2) with 3 variations of the measurement position on the beam. The 6061 series aluminum beam used have length: 80 cm, height: 32 cm, and width: 32 cm. Data were collected experimentally using a vibration meter to measure beam vibrations at the various positions from the cantilever beam at a distance from support: 10 cm, 35 cm, and 60 cm. The results of the analysis showed that the values ​​of the displacement, velocity and acceleration of the object vibrations change when the measuring point was far from the cantilever support. The maximum displacement value is at 60 cm from the support: 0.02 mm, and the lowest is at 10 cm: 0.12 mm. The velocity value also increases, maximum at 60 cm from the support: 38.58 mm/s and the minimum value at 10 cm: 12.30 mm/s. While the acceleration value, the maximum at 60 cm from the support: 91150 mm/s2 and the minimum at 10 cm: 66900 mm/s2.

Experimental Investigation on Vibration Responses of Fiberglass Reinforced Plastic

“…When the beam was vibrated and the vibration displacement was measured at a point 450 mm from the cantilever support or the farthest measurement position, the value of the vibration displacement reached maximum value was compared to other points or at position 50 mm and 250 mm from the cantilever support. This was because at the measuring position of 450 mm and then the beam was vibrated under certain conditions, the beam tends to get a greater displacement than the measured position near the cantilever support [14], [15].…”
