摘要： PROBLEM TO BE SOLVED: To provide a method for facilitating strength analysis of a fastened structure in a short time through simple structure.
SOLUTION: In the method for analyzing the strength of a fastened structure obtained by fastening a male thread member 1 to a female thread member 2, springs acting in the radial, circumferential and vertical directions of a node at a screw thread contact portion between the male thread member 1 and the female thread member 2 are assumed, and spring constants kr, kθ and kn equivalent to a stress received by the contact portion are determined and defined for the respective assumed springs, whereby calculation necessary for strength analysis is performed while substituting the stress received by the contact portion by the springs. Since the analysis of the springs can be linearly treated, repeated calculations due to the conventional nonlinear analysis is not required, and the calculation necessary for strength analysis can be facilitated in a short time.

摘要： PROBLEM TO BE SOLVED: To analyze a catalyst layer on the basis of an actual physical structure of the catalyst layer.
SOLUTION: The physical structure of the catalyst layer is formed into a two-dimensional geometric model so as to be suitable for numerical analysis. Elements constituting the catalyst layer are modeled into circular carbon carriers 40 and binders 42. Here, each carbon carrier 40 carries a catalyst alloy. Each binder 42 shows a function of condensing and coupling the carbon carriers 40. The carbon carriers 40 adjacent to each other are modeled when coupled with each other via the binder 42. A part surrounded by the carbon carriers 40 coupled with each other via the binder 42 is modeled as an air hole 44 that allows gas or liquid to freely come in and out. Boundary conditions are applied to the geometric model so as to execute deformation analysis of the catalyst layer by a finite element method.

摘要： PROBLEM TO BE SOLVED: To determine the exhaust property and drainage property of a three-dimensional porous body through which fluid flows according to the degree of bending of a channel formed in a virtual three-dimensional porous body image by making virtual fluid flow through the virtual three-dimensional porous body image model. SOLUTION: Virtual fluid 10 displayed by a speed vector in a rectangular parallelepiped virtual three-dimensional porous body image equipped with a channel through which a virtual fluid 10 runs is made to flow from a ZX face to an opposite face, and the channel is determined as the continuum body of the speed vectors. The porous body image including the channel is divided into n in parallel with the ZX face so that n pieces of layers can be created. The Y components of the continuum of the speed vectors are extracted, and the layers including the speed vectors corresponding to each layer are sequentially arranged from the upstream to downstream, and the maximum speed vectors are extracted for each layer. From path length F of a connection curve obtained by successively connecting the start points of the maximum speed vectors and length S between the start points of the speed vectors of the layers of the uppermost stream and the lowermost stream, F/S is computed so that the arithmetic value can be defined as the degree of bending of the porous body.
