Abstract：Corrugated cores sandwich panel as a lightweight construction has broad application prospects. The sandwich core is mainly responsible for the mechanical properties of sandwich panel. Based on the summary of existing corrugated cores sandwich panel types, 20 kinds of corrugated cores sandwich panels are sorted out and conceptual design of structures are established. At the same time, the lateral crushing mechanical behavior of various forms of sandwich panels are taken with the finite element software Abaqus. The parameters of crushing performance, deformation mode and energy absorption are compared. The results show that five kinds of sandwich planels V-I, II, III, IV and U-I, which have characteristics of higher specific energy absorption and specific strength, are better choices for energy-absorption structure. Then three kinds of sandwich planels U-IV, Circle Tube-I, U-II of high specific energy absorption can be used as energy-absorption structure under certain conditions.
