摘要

PPROBLEM TO BE SOLVED: To provide a modeling method of shock absorber for forming a finite element model capable of accurately analyzing a shock absorber constituted by collecting a plurality of cylindrical bodies, and an analysis method of shock absorber capable of accurately analyzing a shock absorber using the finite element model formed by the modeling method of shock absorber. PSOLUTION: In the finite element model 20B for analyzing a real object 20A of an aluminum honeycomb 20 that is an assembly of a number of honeycomb grids 22 each formed in a cylindrical shape having a parallel axial line by finite element method, the honeycomb grid 2 has a virtual dimension tb set larger than the dimension ta of the honeycomb cell 22 in the real object 20A, and the virtual plate thickness tb is differed from the plate thickness ta of the real object 20A so that the same compression stress as in the real object 20A is caused when the same compression load as in the real object 20A acts thereon.
