Problems solved by technology
[0003] The purpose of the present invention is to overcome the problem that the existing rubber components of railway locomotives are not suitable for the analysis of the rubber components of the railway locomotive with the cord structure, which easily leads to the inability of the analysis to converge, and propose a rubber component analysis of the railway locomotive that can adapt to the cord structure, so as to promote the smooth analysis Method for Analyzing Rubber Components of Railway Locomotives

Embodiment Construction
[0011] The following will be combined with figure 1 The flow chart of the present invention is further described.
[0012] As can be seen from the accompanying drawings, a kind of cord structure railway locomotive rubber component analysis method that the present invention relates to adopts a common node analysis method, and the geometric model of the railway locomotive rubber component is first imported into grid processing software (such as HYPERMESH supernet grid division tool) for mesh division processing, and cut the geometric entity at the position of the ply; then perform volume mesh division on the rubber component (hexahedron or hexahedron-based volume grid); and then extract the ply where The surface grid of the cutting surface is set separately as a surface grid set SURFACE (surface set); the remaining volume grid is set as a volume grid set SOLID (volume set), so that the cord and rubber are coplanar and also coplanar. Nodes, to generate a common node grid; then i...

The invention discloses an analytical method for a rubber member of a railway locomotive with a curtain structure. The analytical method comprises the following steps of: importing a geometric model of the rubber member of the railway locomotive into mesh processing network (such as Hypermesh) for meshing processing; cutting a geometry solid at the position where a curtain layer is positioned; carrying out solid meshing on the rubber member (the solid mesh of hexahedron or the solid mesh comprising the hexahedron); extracting a face mesh of a cutting surface where the curtain layer is positioned and separately setting the face mesh into one mesh set superface (face set); setting the residual solid mesh into a solid mesh set (body set), enabling the curtain and rubber to be coplanar and form conode simultaneously and generating a conode mesh; and respectively importing the superface and the solid into finite element analytical software and carrying out subsequent conventional analytical calculation.
Description
technical field [0001] The invention belongs to an analysis and test method for railway locomotive components, in particular to an analysis method for railway locomotive rubber components, in particular to an analysis method for railway locomotive rubber components with cord structure. Background technique [0002] The elastic components of railway locomotives involve elastic damping performance, so performance testing is generally required. The main material of elastic components of railway locomotives is rubber, which belongs to superelastic materials and has a small elastic modulus. Large, highly non-linear. And the rubber member of the railway locomotive with the cord structure has a more complicated structure because one or more layers of cords are sandwiched in the middle. In order to ensure the performance of the product, the technical performance analysis is generally carried out during the product design, and now the rubber components of the railway locomotive are ...
