The importance of material selection and structural design of suspension rubber buffer

- Aug 23, 2018-

The suspension rubber buffer block is a type of cushion rubber product, which mainly functions to absorb impact energy and mitigate impact. Since the rubber impact stiffness is greater than the dynamic stiffness, the dynamic stiffness is greater than the static stiffness, which is beneficial to reduce impact deformation and dynamic deformation. Suspension rubber buffer blocks are widely used in various vehicles and road rolling machinery.


In general, the suspension rubber bumper should have sufficient vertical stiffness to ensure that it can reliably transmit the reaction force of the upper structure of the support to the abutment. The support has good elasticity to cope with the rotation. At the same time, it should have a large shear deformation capacity to meet the horizontal displacement of the upper structure. The arrangement of the rubber blocks is mainly related to the structural form used in the field.


We know that rubber is a very outstanding wear and impact resistant material, so the suspension rubber buffer block has the characteristics of anti-wear, corrosion resistance, anti-fouling, vibration and noise reduction. Of course, the suspension rubber buffer block is not composed of only the rubber layer. The quality of the buffer block should not only have a high elastic rubber layer but also the quality of the wear layer and the design and selection of the fixed support structure.
