3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
It is used to reduce the vibration level of the rail-under-foundation generated in the operation of urban rail transit, thereby reducing the installation of vibration and vibration
Set. It relies on rubber material compression, shear or compression - shear deformation to buffer the vibration generated by train operation.
3.2
The ratio of dynamic stiffness to static stiffness of a shock absorber measured at a certain excitation frequency.
4 requirements
4.1 appearance
4.1.1 rubber
a) The shock absorber rubber surface should be smooth, no bubbles, cracks, cracks, loose and metal degumming (metal and rubber vulcanized shock absorber)
phenomenon;
b) Shock absorber rubber surface When the rough rough or mold rough marks exist, the depth of depression should not exceed 1mm, the area should not be greater than
5mm2, the number should not be more than three.
