Computer aided design system of cushioning materials

The methods (C-sigma_m curve and Gm-sigma_s curve) those are adopted from the Chinese standard GB8166-87 and used for the cushioning material design in voyage, architecture, automobile, transportation, and package fields have many shortcomings. The novel cushioning defense technique - energy absorption diagram method - were adapted to optimization design of cushioning materials in this paper. For this purpose, in the paper the demand, functions and modules of the computer aided design system of cushioning materials were analyzed. Then the system was designed particularly, and the energy-absorption-diagram production and optimization modules were mainly designed and realized. Finally some common examples on cushioning package design were computed in the final system, and the results from the final system and the methods in GB8166-87 were analyzed in contrast. The analysis and drop experiments on the designs according to the energy-absorption-diagram method proved that it is more reliable and efficient for this method to be used in the cushioning material optimization design than the methods in national standard GB8166-87
