Abstract: The drop simulation analysis refrigerator of the refrigerator is carried out in accordance with the test standard. The simulation results show that due to the unreasonable design of the original packaging structure, the support plate of the press is deformed beyond the yield stress and cannot pass the drop test. Combined with simulation analysis and dynamics theory, the optimal design scheme of the base is proposed. The simulation results of the optimization scheme show that the support plate has no obvious deformation and can pass the drop test, and the final optimization scheme can pass the test at one time. Not only is the packaging cost reduced through simulation analysis and optimization, but the packaging's ability to protection products is also improved.
