Abstract: At present, the research on the refrigerator door mainly focuses on the improvement of the strength and deformation of the door, and the door has a relatively large dimension in the thickness direction. The thickness and material of the door body are different, and the correlation between the door body strength and the strength of the door body is also less researched. Aiming at such problems, taking the existing refrigerator door body as the research object, the refrigerator door body with different material panels is thinned according to the same amplitude, and the change of the deformation amount is studied. Through simulation comparison and analysis, after the door body is thinned to the same thickness, the deformation of the color panel door body and the glass door body. And it was verified through experiments that the deformation of the color panel door body is obviously smaller than that of the glass door body, which is in line with the simulation results, which further verifies the feasibility of replacing the door panel with color panels.
