A certain model of sink-type dishwasher is taken as the object of study, for which cushioning transportation packaging is designed and simulation calculations are carried out. Following the “six-step method” of cushioning packaging design, the cushioning transportation packaging scheme is designed by analyzing the distribution environment of the product, determining the fragile parts and brittle value of the dishwasher, and choosing EPS with a density of 25 kg/m3 as the cushioning packaging material. Firstly, the material model of LS-DYNA is perfected through the material test of different strain rates, then the finite element simulation analysis of the packaging parts is carried out based on LS-DYNA, and the simulation analysis of three kinds of working conditions of the packaging parts is carried out respectively in combination with the relevant test standards. The results show that the maximum response acceleration of prismatic fall is 38.4g, the maximum response acceleration of angular fall is 26.7g, and the maximum response acceleration of face fall is 23.6g. All the maximum response acceleration of each condition is less than the permissible 61g brittle value of the product, and the designed packaging solution meets the buffer demand of the product in the transportation process.
