The report with which the form factor like axis compressive collapse and the factor analysis of the high strength steel of the lightening means are combined is not so seen for compressive collapse of the dynamic bend material. It aimed at the design manual making to be simply predictable of dynamic bend collapse load of the collision structure material from the structural design size and the material characteristic using the steel lamina hat material of a dynamic bend, and then, dynamic bend collapse load was denned from the dynamic bend examination and collision CAE analysis, and the adjustment examination of analytical accuracy was done in the first report of this text in this research. The main results obtained in this study are summalized as follows ; (1) An analytical condition that the correlation of the experiment value and collision CAE analysis result was able to be taken can have been done. (2) When the high-speed collision bend is examined, it is near the performance value that we request, and the difference influence of the experiment etc. of the load value arranged by the Energy Absorption (EA) conversion than the fulcrum reaction force is less. (3) When the high-speed collision bend by this research is examined, the influence of the material span is not seen. (4) The collapse load value calculated from fully plastic moment method, the experiment, and the analysis becomes the value of about 1/2 from fully plastic moment method.
