Anti-vibration rubber plate

Vibration-damping rubber is a general term for rubber vibration isolators, primarily used to reduce noise and cushion shock hazards through shock isolation and vibration mitigation, and is applied in mobile vehicles, rail transit, building isolation pads, 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 vibration damping effect. The vulcanization system affects the material 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 performance. In terms of structural design, it is divided into compression-type, shear-type, and composite types, with dynamic modulus adapting to different requirements based on the load direction [2]. Building isolation pads 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, with the application of new materials and virtual simulation technology driving the product towards high precision and high-performance development.
