The work aims to optimize the packaging of electric cookers, and compare the packaging effects and alternative possibilities of EPS and corrugated liners. With reference to the environmental parameters of the electric cookers during the product flow, the finite element modeling and constraint processing were performed on the product. Based on the finite element concept in Ansys Workbench, the deformation, stress, strain and damage of the product under different mechanical loading effects were obtained through modal analysis, random vibration and drop. The packaging design of the electric cooker was optimized by changing the packaging liner. The optimized package was subject to the simulated analysis and compared with the original package. The maximum stress occurred at the bolted joints of the product. The maximum stresses of bare metal, EPS foam packaging and corrugated (B fluted) packaging were respectively 353.25, 115.69, 171.84 MPa. Although the compressive strength, impact resistance and vibration resistance of corrugated liners are all worse than EPS foam packaging, they can still protect electric cookers well. Therefore, corrugated packaging with good packaging structure design can replace traditional EPS foam packaging.
