In recent years, due to the continuous development of rail transit in China, vehicle sections are also used as places for parking, checking, preparing, operating and repairing vehicles. The subway vehicle section has large floor area, more urban construction land can be obtained by comprehensively utilizing the upper space of the subway vehicle section for property development, the urban land utilization rate is solved, the urban construction land has wide application prospect in large cities with abnormally short land, but the vibration noise problem of the subway vehicle section as the upper cover property influences the normal life of people all the time, the requirement of technical standards cannot be met, and the use performance of buildings is greatly reduced. It is to be understood that in the known vibration control measures, the vibrations are not completely eliminated, but are only attenuated by this technique until the effect of the vibrations is within the range allowed by us.
The measures for vibration reduction are various, and the vibration reduction from the vibration source can be adopted. For example, vibration response of the ground can be theoretically reduced by using vibration reduction fasteners such as double-layer nonlinear fasteners and floating rail fasteners on a subway rail, but sometimes the ground vibration is amplified, particularly the floating rail fasteners and the double-layer nonlinear fasteners can shift the vibration to a low frequency, and the natural frequency band of the floor slab is generally 0-10Hz, which often causes structural resonance, and is suitable for the contrary. The expected damping effect is often not achieved, and due to the adoption of the damping fastener, the vertical rigidity of the fastener is lower than that of a traditional fastener, so that the strength of the track is reduced, and the occurrence of grinding and wave grinding defects of the side of the steel rail is caused.
From the propagation path of the vibration, a processing means for damping and absorbing the vibration on the propagation path of the vibration is provided to reduce the influence of the vibration on the upper structure and greatly improve the service performance of the structure.
The working principle of the hydraulic viscous damper is that when the damper is impacted by the outside, the cylinder body and the piston generate relative motion, the volume on one side of the piston is reduced, viscous damping materials are forced to flow to the side with the increased volume through a gap, and the shear flow of the damping materials generates damping force to dissipate impact energy, so that the purpose of buffering is achieved. The damper is expected to generate great resistance, can limit the displacement of the steel rail, and can absorb energy and share impact force.
The dynamic vibration absorber is an important vibration damping device in the field of vibration control, is widely applied in the industry, and from the practical point of view, the dynamic vibration absorber is required to be insensitive to the influence of environmental factors such as temperature change and the like, and is convenient to install, and the particle damping vibration absorber achieves the effect of dissipating energy through the damping of an internal structure in the vibration process through the structure so as to control vibration.
