The work aims to address the computer aided cushioning performance evaluation and optimization cushioning design of two-dimensional (2D) cellular materials under impact loading. The finite element model was created for the cushioning performance analysis of 2D cellular materials, and the cushioning performance evaluation indicators and their calculation methods were illustrated. The overall functional modules and system database were designed, the general functionality flow was planned, and the final software was developed with the C++ Builder development environment. The software consisted of four modules including data management, pre-processor, post-processor and optimization design. The pre-processor input the base material type, structural parameters and load conditions, automatically generated the finite element model files for the cushioning performance analysis of 2D cellular materials, and executed the corresponding computations by calling the ANSYS/LSDYNA software. The optimization design module produced the corresponding product cushioning optimization design file after inputting the relevant parameters of the impact body and base material. The data management module could manage base material parameters, results of cushioning performance analyses, and optimization design results. The system database was composed of data tables of base material specifications, performance parameters, cushioning performance analysis results, optimization design project data and detailed optimization results. The main interface of the developed software and its corresponding menu items for each module are presented, with comprehensive functionality and user-friendly windows.
