It is investigated if it is effect that Truss-core panel can be used for vehicle body panel and Reversed Spiral Cylindrical Origami Structure (RSC) can be used for Vehicle member for vehicle weight reduction drastically. It is difficult that truss core panel is pressed homogeniously with simple press for the numerous arrangements of tetrahedral convex. For that reason, the multistage forming simulation method is developed and tested with many kinds of materials. The results of test suggest that the method has excellent characteristics. It was shown that RSC in simulation has the structure whose amount of energy absorption is larger than going side-member of rectangular section. The possibility of reducing greatly the weight of vehicle is expected in Origami Engineering by hydro forming test.
