Problems solved by technology

For large-scale finite element nonlinear calculations (such as composite air suspension systems), it is impractical to carry out finite element modeling and analysis of rubber bushings directly according to the actual model, because the actual rubber bushing products are for To obtain a sufficiently large radial stiffness, metal plates are generally added to the rubber, and the geometric characteristics of the rubber layer and the metal layer are generally small, and the structure is relatively complicated. If the actual rubber bushing model is directly modeled, the finite element The meshing branch is very small, and when it is used for large-scale finite element nonlinear analysis, the calculation time is very huge, and the calculation is easy to fail to converge
[0003] The analysis method in the prior art uses different optimization algorithms to identify the constitutive parameters of rubber, which is suitable for the design and analysis of the structure of the rubber bush itself, but not suitable for the field of large-scale finite element nonlinear analysis

Abstract

The invention belongs to the technical field of rubber bushing manufacturing, and discloses a large-scale finite element analysis method for a rubber bushing. According to the large-scale finite element analysis method for the rubber bushing, a simplified rubber bushing model is used, grids are divided, model parameters needed by simulation calculation are obtained through the design value of the rubber bushing, on the premise that the simulation accuracy is not reduced, the number of the grids needed by simulation calculation is reduced, the time needed by simulation calculation is shortened, and the simulation efficiency is improved. And the efficiency of simulation calculation is improved.

Description

technical field [0001] The invention relates to the technical field of rubber bushing manufacturing, in particular to a large-scale finite element analysis method for rubber bushings. Background technique [0002] Rubber bushings are often used for the connection between various components of commercial vehicle chassis suspensions. While reducing vibration, they also transmit the force between components. Therefore, their own static stiffness (radial stiffness and torsional stiffness) directly affects the assembly components. of stress. For large-scale finite element nonlinear calculations (such as composite air suspension systems), it is impractical to perform finite element modeling and analysis of rubber bushings directly according to the actual model, because the actual rubber bushing products are designed to To obtain a sufficiently large radial stiffness, metal plates are generally added to the rubber, and the geometric features of the rubber layer and the metal layer...
