The work aims to study the deformation of the thin-type kitchen ventilator package under drop condition, and put forward the rectification direction and specific measures according to the test and simulation analysis results. The drop condition causing product deformation was determined according to the drop test method of transport packages. Based on Creo and Ansys Workbench software, the drop simulation analysis of product packages was carried out, and the displacement and stress distribution of products were obtained. The consistency between resonance frequency measured by sweep frequency test and the natural frequency of modal analysis proved that the finite element model established was reasonable. The conservation of energy in the drop process proved that the analysis result was correct. The maximum displacement was distributed on filter, volute and motor. The maximum stress was distributed on the product shell. In addition, the trend of acceleration obtained from laboratory test varying with time was basically the same with that obtained by simulation analysis. In order to analyze the drop deformation of products, laboratory tests and finite element simulation analysis can be combined to comprehensively evaluate the deformation and stress concentration of products. The deformation problem of the thin-type kitchen ventilator can be solved by adding pads and improving the product structure, etc. The validation of the finite element model and the conservation of energy in the analysis process can ensure the correctness of the finite element analysis results.
