Abstract EN
This research deals with the evaluation of buckling behavior for 6061-T4 aluminum alloy under increasing compressive dynamic loads.
Two types of columns, long, and the intermediate columns were used.
The number of specimens used in the dynamic axial compression test were 9 samples .(1%) of the length column is the allowable lateral deflection.
For the purpose of calculating the initial deflection, the digital dial gauge was used and the instrument was set at a distance of (0.7) of length from the fixed condition for the column.
A control system is designed to evaluate the critical buckling and to prevent sample failure.
The control system consists of a measuring circuit (transmitter circuit) with a flex sensor installed at 0.7 of the total column length of the column's fixed condition.
In addition, the system contains a shutdown circuit (receiver circuit) to switch off the machine at critical load with a mobile phone for the purpose of displaying deflection data.
The connection between the transmitter circuit and the receiver wirelessly through the RF sensor and between the transmitter circuit and mobile phone also wirelessly via Bluetooth.
The results obtained were experimentally compared with the Perry-Robertson formula.
It was found that the Perry-Robertson formula was a good agreement with the experimental results with a safety factor of (1.2).
