This article studied in detail the impact of various related factors on the mechanical properties of lead rubber sandwich cushions in China. At the same time, the long-term performance of lead-insulated rubber cushions in China was studied. The study included vertical pressure, frequency and shear deformation. , the number of cycles, the effect of temperature on the mechanical properties of the shock-absorbing pad such as stiffness and damping; the effect of the durability of the shock-absorbing pad such as temperature aging and creep on the stiffness, damping characteristics and ultimate deformation capacity of the shock-isolation pad. The degree of influence of shear and vertical low-cycle fatigue tests on the mechanical properties of the isolating pad.
