Absorber 1 which has high rigidity is of cylinder structure whose rubber material in horizontal radial direction bears compression force, damping fluorosilicone rubber can be implemented to adjust the stiffness of rubber material for appropriate horizontal rigidity.
Absorber 2 is of T-shape connected by metal material, which has obvious setback in structure for small deformation of rubber will lead to worse damping effect.
