Abstract:Based on the compression test results of metal rubber bearings, a systematic study of its mechanical properties is carried out. Through experimental data analysis, a significant linear relationship between tangent modulus and stress is identified. Furthermore, the analytical integration method is used to build a compression constitutive model represented in the form of an exponential function. The results indicate that the tangent modulus of the bearing presents a good linear variation trend with increasing stress. The proposed exponential constitutive model can accurately depict its nonlinear stress-strain response and closely aligns with experimental data. The research result not only provides theoretical support and methodological basis for the refined mechanical modeling of metal rubber bearing, but also has the significant guiding value for its structural optimization design and engineering applications. Simultaneously, a solid theoretical and methodological foundations are laid for related numerical simulation analysis.
