Problems solved by technology
However, whether the analysis is terminated due to excessive mesh distortion or the analysis calculation is completed by using other auxiliary analysis techniques, there is a common feature: that is, the mesh distortion is particularly serious, and the stress and strain at the mesh distortion will have a sudden change. Eventually the stress results are discontinuous and unrealistic

Embodiment Construction
[0027] like figure 1 and figure 2 As shown, in this embodiment, the middle part of the rubber-metal composite stopper with a trapezoidal cross-section is the rubber part 10 , and the ring parts at the upper and lower ends of the rubber part 10 are metal parts 20 .
[0028] like Figure 1 to Figure 7 As shown, the grid generation method for rubber-metal composite stopper large deformation rubber analysis in this embodiment includes the following steps:
[0029] S1: Select the sectioned rubber section 1 from the three-dimensional geometric model of the rubber-metal composite stopper, and determine that the rubber section 1 has a "mouth"-shaped outer contour 2;
[0030] S2: Divide the inner contour 3 of the "口" font in the outer contour 2 of the "口" font, and determine that the inner contour 3 of the "口" font and the outer contour 2 of the "口" font form an overall outline that is the overall outline of the "back" font ;
[0031] S3: Connect the adjacent vertices of the inner...

The present invention discloses a grid generating method used for an analysis of rubber-metal composite stopper large deformation rubber. The method comprises the following steps: S1: selecting a split rubber section from a three-dimensional geometrical model of a rubber-metal composite stopper, and determining that the rubber section has a square-shaped outer contour; S2: dividing a square-shaped inner contour in the square-shaped outer contour, and determining that the square-shaped inner contour and the square-shaped outer contour compose a concentric-square-shaped overall contour; S3: forming a centrally located central region and four surrounding regions that are separately set at the circumference of the central region by connecting separately adjacent vertices of the square-shaped inner contour and the square-shaped outer contour; and S4: separately performing grid division and layout on the central region and four surrounding regions. The grid generating method provided by the present invention has an advantage that a grid changes from a relatively poor grid to a better grid in the process of flow deformation so that an analysis can be successfully completed.
Description
technical field [0001] The invention relates to the technical field of large-deformation rubber characteristic analysis, in particular to a grid generation method for the analysis of large-deformation rubber for rubber-metal composite stoppers. Background technique [0002] The rubber-metal composite stopper belongs to the field of railway locomotive bogies, and is a rubber-metal composite elastic component on the railway locomotive bogies. The rubber-metal composite elastic components of railway locomotives involve elastic vibration damping performance, so performance testing or testing is generally required. The conventional method is to conduct finite element analysis or test testing, and the method of finite element analysis is time-consuming due to its low cost. The advantage of less is often widely used, so now generally use finite element analysis technology to analyze rubber-metal composite elastic components; but when using finite element technology to simulate the ...
