Abstract： In order to reduce the weight of the container and extend its service life while ensuring structural safety，a 4O-foot container was taken as the research object. A simulation model was established through Abaqus and the mass of the container side panel and the maximum stress of the side wall experiment were used as evaluation indicators to analyze the structural parameters of the container side panel. Based on the Box-Behnken Design in the response surface method to design the test scheme，a response surface model was established with wave height， inclined wave width and ladder surface size as design variables，and the mass of the container side plate and the maximum stress on the side wall experiment as optimization objectives. And through variance analysis and correlation analysis of the response surface model，the influence degrees of each parameter on the quality of the container side panels were determined in the following order： ladder surface size > wave depth > inclined wave width；The degree of influence on the maximum stress on the side wall experiment is in the following order： inclined wave width > wave depth > ladder surface scale. The best parameter combination was obtained within the optimization range，namely： the wave depth was 45.5mm ，the ramp width was 66.5mm ，and the ladder surface size was 79.5mm . Based on this parameter combination，the model was re-modeled and simulated. A comparative analysis was conducted with the original parameters. The weight was reduced by 4.8% ， and the maximum stress it was subjected to also met the design requirements.
