<p>PROBLEM TO BE SOLVED: To provide a method for preparing a stress analysis model for a bogie frame of rolling stock, capable of easily displaying stress required in the stress analysis on the of the bogie frame as a whole. SOLUTION: The bogie frame of the rolling stock is divided into many meshes, a plate model 2 part and a solid model 1 part are made to coexist in the meshes, and stress analysis is performed by a finite element method. A thin film model 3, having the same material characteristic as that of the plate model 2 and sharing the same point with an outer surface 1a of the solid model 1, is adhered to the outer surface 1a.</p> |
