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/s 2 ) with 3 measurement positions on the cantilever beam. The 6061 series aluminum beam being used have length of 80 cm, height of 32 cm, and width of 32 cm. The 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, respectively. 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 0.02 mm at 60 cm from the support, and the lowest value is 0.12 mm at 10 cm. The velocity value also increases, maximum value is 38.58 mm/s at 60 cm from the support, and the minimum value is 12.30 mm/s at 10 cm from the support. Accordingly, the acceleration value is maximum at 60 cm from the support: 91150 mm/s 2 and the minimum at 10 cm: 66900 mm/s 2 .
