| Abstract: |
| The work aims to verify whether the OSB board can be used for the production of the pallet, and verify the stress and strain of the OSB board pallet during the forking. The model of OSB board pallet that was connected with the steel nail model was established by Solid Edge. The finite element analysis on the pallet model was carried out by the NX Nastran simulation module in the software. The stress and strain distribution diagram under the pallet fork condition was obtained and the fork test on the OSB board pallet was done. Through the finite element simulation analysis and practical experiment of the OSB board pallet, the maximum deformation of the simulation under the load of 6.5 kN was 16.75 mm, and the maximum deformation of the actual experiment was 18.2 mm. The two values were approximate, which verified the validity of the finite element analysis. The practicality of the OSB board pallet and the feasibility of analysis, validation and optimization of pallet performance in the finite element method at the pallet design stage are confirmed. |
