Finite element analysis of the boom of crane loaded statically

الملخص EN

In this paper, the finite element analysis was carried out on boom of telescopic crane using ANSYS package software and the manual calculation as well as the analysis by the strength of materials procedure.

The stress picture along the boom model was conducted under the maximum load carrying capacity.

The stress developed at the interception of hydraulic rod with the first tube is higher than that developed along the rest of the boom.

Moreover, the maximum deflection occurs at the boom head sheave. In order to investigate the accuracy of the results, a comparison between the two approaches and the exact obtained by the strength of materials procedure is carried out. Although the high capabilities of ANSYS software, the results are somewhat less accurate than that obtained by the manual calculations.

Besides that, the results obtained by the finite element manual calculations are wholly similar to that of strength of materials procedure.

Model taken for this paper is TADANO TR-350 XL 35-ton capacity.
