Optimization of Refrigerator Door Structure Based on ABAQUS

摘要

The refrigerator door cover deformation or cracking is a major flaw in the BCD268 refrigerator. In this paper we create a simplified model of the refrigerator door. Based on the standard modules of ABAQUS finite element analysis software, this paper analyzed the deformation mechanism of the refrigerator door, and determined the parts of the deformation. Aiming at the deformation and cracking, the numerical simulation of BCD 268 door cover was conducted, and two kinds of different options to strengthen the ribs were proposed, then the two programs were carried out through finite element analysis, and prototypes were fabricated high and low temperature impact test for validation. Optimal structure scheme was verified by contrast. The designed lower-door covers were produced in small scale, and it proved to be consistent with the numerical results of finite element.
