Research and application of thermal deformation simulation of refrigerator door based on topology optimization
Focusing on the deformation problem of refrigerator door under thermal load,the topo-logical optimization method was adopted for simulation research,and its application in practical design was explored.The results showed that the bending phenomenon occurred after the cold and thermal shock test of the refrigerator door body,and the deformation trend was basically con-sistent with the simulation results.The maximum deformation of the door on one side was less than 2.5 mm after optimization,and the mass of the reinforced iron component was reduced by 32%,so that the door structure not only met the lightweight requirements,but also ensured that the deformation met the design requirements,and realized the effective control of thermal deforma-tion.It provided a new idea for the optimization design of refrigerator door.
