Keywords: rubber0 a sealingring; includedangles; finiteelementanalysis; contactpressure1 penalty function finite element contact algorithm in the theoretical structure of the rubber seal is a large deformation, nonlinear contact problems, while there is geometry, material and boundary non-linear, and thus this paper, the contact element The penalty function method for analysis, impact toughness at room temperature in two connected correlation coefficient of r = 0.95, 40 ℃ impact toughness of a correlation coefficient = 0.93. The calculated r. ~ R5 values were greater than 0.834,[link widoczny dla zalogowanych], so this study were derived from the linear equations is very significant linear relationship. 4 Conclusion (1) the orthogonal design method is derived by high-strength weld metal mechanical properties of carbon equivalent formulas that reflect the various alloying elements on the weld tensile strength,[link widoczny dla zalogowanych], yield strength, elongation and impact toughness level. Therefore, high-strength weld,[link widoczny dla zalogowanych], Mo and Ni on the low-temperature impact toughness improvement. (2) the establishment of the carbon equivalent and mechanical properties of the weld between the various equations. Using these equations can be approximated based on the chemical composition of the weld to calculate the corresponding mechanical properties. (3) of the equation used to test the significance of that correlation coefficients of the parties to the program were more than 0.93, indicating that these formulas have a very significant linear relationship.
