Vibration-damping rubber is a general term for rubber vibration isolators, primarily used for noise reduction and shock buffering by isolating and mitigating vibrations, and is applied in fields such as mobile vehicles, rail transit, building vibration isolation supports, and industrial equipment [1] [3-4]. Its performance indicators include static stiffness and damping coefficient tanδ, where the latter needs to maintain a higher value and wide-peak characteristics within the operating frequency and temperature range to optimize the vibration damping effect. The vulcanization system affects the material's stiffness, heat resistance, and fatigue life; traditional vulcanization systems can improve fatigue resistance but are limited in heat resistance [1-2]. Butyl rubber and nitrile rubber have higher damping coefficients in rubber materials, while natural rubber boasts excellent comprehensive properties. In structural design, it is divided into compression type, shear type, and composite type, with dynamic modulus adapted to different needs based on the load direction [2]. Building vibration isolation supports use a composite structure of stacked rubber and steel plates, reducing seismic response through horizontal deformation and lead core energy dissipation [3]. The global market size continues to expand, with the application of new materials and virtual simulation technology driving products towards high precision and high-performance development.
