Abstract
The present work proposed the improvement of a commercial plastic pallet project focusing its sustainability by reducing the amount of material, without compromising its load capacity. A numerical modeling was simulated in the SOLIDWORKS® environment, analyzing the mechanical behavior under static loading and using the properties of the PELBD material during the resolution by the computational solver of the software. In the simulation of the original plastic pallet, a numerical analysis of the current model and the proposed new model was carried out, respecting the ABNT NBR 16242, ABNT NBR 8334 and ABNT NBR 8252 Standards. Initially, the structure of the plastic pallet was analyzed and a CAD file was generated, using the dimensions of the technical sheet of the product, then, the finite element model (FEA) was developed, with the creation of the geometric mesh, establishment of the material properties (PELBD) and application of the distributed load of 1500.00 kg, between the three support beams of the pallet as well as the support restrictions. Finally, with the results of the solver, the topology feature of the software can be used to generate an optimized model. In this solver, Intel Direct Sparse, carried out the analysis in the mass removal test, by the rigidity criterion of the PELBD material, incorporated into the pallet. Based on the results of the percentage removal of this material, it was possible to readjust the new plastic pallet, reproducing all the previous steps, to geometrically and structurally validate the proposed improvements. Results showed that the mechanical resistance of the new model was superior in relation to the commercial pallet, which proved to be adequate to reduce both the elastic displacement of the material and increase rigidity in controlling tensions during loading. Additionally, the new model promoted a material reduction of up to 25% of the total weight of the commercial pallet, improving its sustainability.
