3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
rubber spring isolator
Applied to the floating slab track structure of urban rail transit, the use of rubber spring deformation energy consumption reduces the vibration isolation transmitted by the wheel-rail vibration to the surrounding
element.
3.2
loss factor lossfactor
tanβ
In the dynamic load and time history, the tangent of the phase lag angle β between the load and the deformation.
4 Structure and Model
4.1 Structure
The rubber spring vibration isolator is mainly composed of a rubber spring, a height adjusting device, and an outer sleeve. The structure is shown in Figure 1.
