The work aims to improve the buffer package structure of the side suction range hood based on the drop test and simulation study of the package of the side suction range hood. Firstly, the original scheme of drop test was carried out on the package of the side suction range hood. Then, a 3D model was established with Pro/E software, and the drop simulation analysis was carried out with Workbench and LS-DYNA software. Finally, combined with the drop test and simulation results, the design of buffer package structure was improved, and the simulation verification was carried out. Through the drop test, the damage of the bottom and side cushions as well as the body of the range hood was observed, and the impact acceleration value of the parts of the support frame under each drop condition was obtained. Compared with the drop test and simulation analysis results, the error of the two was within 9%. The improved design and simulation verification of the original scheme were carried out based on the experimental and simulation analysis results, showing that the pulse time of the original scheme decaying to 0 m/s from the initial velocity value of 2.97 m/s was 10.3 ms, and the maximum acceleration value was 43.10g, while the pulse time decaying to 0 m/s of the improved scheme required 14.5 ms, and the maximum acceleration value was 33.41g. The packages of side suction range hood are evaluated by means of experiment and simulation. After verifying the effectiveness of simulation results, the simulation analysis method is used to guide the improved design of buffer packaging. This idea can provide some references for similar follow-up buffer packaging design.
