The work aims to propose a new design method for pulp molding packaging of microwave ovens and establish the simulation standard for judging the pulp molding performance, so as to obtain microwave oven pulp molding packaging with excellent mechanical properties, high reliability, less material consumption, small size, high loading capacity, low cost and short research and development cycle through finite element simulation iteration optimization. Structural element design, finite element simulation optimization and experimental verification based on the mechanics principle of thin-walled structures were carried out. On the premise of reducing the material consumption by 5.5%, the mechanical properties and drop reliability of a microwave oven pulp molding packaging were significantly improved, the research and development cycle was shortened to half of the original, the whole loading capacity increased by 16.4%, and the cost decreased by 14.2%. The new design method can effectively improve the reliability of pulp molding packaging, shorten the research and development cycle and obviously reduce the cost.
