[Abstract]:Aim to verify whether OSB plate can be used in the manufacture of pallet and the stress and strain of OSB plate tray in the process of fork lifting. Methods the OSB tray model connected by steel nail model was established by Solid Edge, and the finite element analysis of the pallet model was carried out by using the NX Nastran simulation module in the software, and the stress and strain distribution diagram of the tray under the condition of fork lifting was obtained. At the same time, the fork lift test was carried out on the OSB tray. Results through the finite element simulation analysis and actual experiment of OSB plate tray, it is concluded that under 6.5 KN load, the maximum deformation value of simulation analysis is 16.75 mm, and the maximum deformation amount of actual experiment is 18.2 mm,. The validity of finite element analysis is verified. Conclusion the practicability of OSB tray is confirmed, and the feasibility of using finite element method to analyze and optimize the performance of the tray in the design stage of the tray is verified.
