This study aimed to investigate the stacking strength of plastic packaging bucket and steel- plastic bucket during high temperature of 40 ℃ . Transportation performance test models and the simulation test conditions of plastic packaging bucket and steel- plastic bucket were established using Solidworks Simulation CAD/CAE software. The stress fields and displacement fields were calculated under high temperature stacking load. The stress state and the deformation distribution were obtained. The maximum stress of plastic packaging bucket reached 21.13% of the yield limit, and the maximal displacement was 4.12 mm; the maximum stress of steel-plastic composite bucket reached 11.09% of the yield limit, and the maximal displacement of 0.0374 mm. Our simulation results also indicated that the stacking height were able to reach 3 m of plastic packaging bucket and steel-plastic bucket with capacity of 200 L and the maximum of Mises stress did not reach the material′ s yield strength when elastic deformation was occurred. Taken together, leak location of packaging containers can be predicted and structural optimization of packaging containers can be achieved by simulation analysis of high temperature stacking strength.
