| Abstract: |
| By analyzing the research progress of rubber environmental damage mechanisms and life prediction models, the construction method of rubber material environmental damage dynamic models was studied. The aging mechanism of thermal oxidation, hydrolysis, hygrothermal aging and mechanical damage of rubber in complex environments and the traditional dynamic method, the constitutive model method and the computer simulation prediction method of rubber life prediction were analyzed. The idea of constructing environmental damage dynamic models from three aspects of environmental action dynamics, thermal analysis methods and multi-scale modeling was discussed. Thermal oxidation and hydrolysis of rubber materials in complex environments are the most important damage mechanisms, but the existing life prediction model does not establish the correlation between microstructure changes and macro performance changes, so the application of the life prediction method has limitations. In order to scientifically and accurately predict the life of rubber materials, it is necessary to study the action process of complex environmental factors on rubber materials from the perspective of dynamics, and establish a dynamic model that can comprehensively describe the environmental damage of rubber from the micro, meso and macro scales. In the future, molecular dynamics simulation will become a key tool to decipher the mechanism of environmental damage, but it still needs to verify and optimize the environmental damage dynamics model with measured data to improve its accuracy and application range. |
