Vibration-damping rubber is a general term for rubber shock absorbers, primarily used for noise reduction and cushioning impact hazards through shock isolation and vibration mitigation, and is applied in fields such as mobile vehicles, rail transit, building shock isolation supports, and industrial equipment [1] [3-4]. Its performance indicators include static stiffness and damping coefficient tanδ, the latter of which needs to maintain a higher value and wide peak characteristics within the operating frequency and temperature range to optimize the shock absorption 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 adapting to different needs based on the load direction [2]. Building shock 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 is continuously expanding, and the application of new materials and virtual simulation technology is driving products towards high precision and high-performance development.
