In which scenarios are the spherical bearings of railway rail transit bridges applied

Railway Rail Transit Bridge spherical bearings are used in a variety of scenarios, mainly including the following categories: 1. wide bridge: for railway bridges with large width, the bridge will produce complex deformation under the action of train load. With its good rotation performance and large displacement, the spherical bearing can better adapt to the deformation demand of the wide bridge,
Railway Rail Transit Bridge spherical bearings are used in a variety of scenarios, mainly including the following categories:
1. wide bridge: for railway bridges with large width, the bridge will produce complex deformation under the action of train load. With its good rotation performance and large displacement, the spherical bearing can better adapt to the deformation demand of the wide bridge, make the stress of the bridge structure more uniform, and ensure the stability and safety of the bridge.
2. curved bridge: the curved bridge will produce large torsional deformation when it is stressed, which requires high rotation capacity of the support. The spherical bearing has the same rotation performance in all directions, and can provide uniform rotation in all directions, so as to meet the stress and deformation requirements of the curved bridge and ensure the safe and stable operation of the train on the curve.
3. ramp bridge: the ramp bridge has large deformation in the vertical direction and also needs to bear the component force of train load in the ramp direction. The spherical bearing can bear a large vertical load and provide necessary rotation in the vertical direction to adapt to the deformation of the ramp bridge and ensure the safety of the bridge structure and the stability of the train.
4. long span bridge: due to its large span, the deformation of Long-span Railway Bridge is relatively large under the action of self weight, train load, wind load, etc. The spherical bearing has large bearing capacity and displacement, which can well adapt to the deformation demand of long-span bridges, effectively transfer the load and ensure the reliability of bridge structures.
5. bridges in low temperature areas: the spherical bearings do not use rubber to bear pressure, and there are no adverse effects such as rubber hardening or aging. They can maintain stable performance in low temperature areas, and are suitable for railway bridge construction in cold climate conditions to ensure the normal use of bridges in low temperature environment.
