Embodiment 1

[0029] Example 1: Such as figure 1 , 2 As shown, this embodiment specifically relates to a piston-type particle damping energy dissipation and vibration reduction sleeper 1. The piston-type particle damping energy dissipation and vibration reduction sleeper 1 includes a sleeper body 2 and a piston-type particle damping element 3 embedded in the sleeper body 2 ; The upper surface of the sleeper body 2 is provided with a rail groove 4; the rail groove 4 is used to install a rail.

[0030] Such as figure 1 , 3 As shown, the piston-type particle damping energy dissipation and vibration reduction sleeper 1 of this embodiment is a long sleeper type, wherein the upper surface of the sleeper main body 2 is provided with two supporting rail grooves 4; the two supporting rail grooves 4 are respectively located in the sleeper main body 2 ends; in this embodiment, the length, width, and height of the sleeper body 2 are 2600mm, 330mm, and 250mm respectively; the sleeper body 2 is made of concr...

Embodiment 2

[0045] Example 2: Such as Picture 10 , 11 As shown, the main difference between this embodiment and Embodiment 1 is that the piston-type particle damping energy dissipation and vibration damping sleeper 1 of this embodiment is a short sleeper type sleeper; the upper surface of the sleeper body 2 of this embodiment only has one supporting rail. Slot 4; in this embodiment, the length, width, and height of the sleeper body 2 are 1200mm, 330mm, and 250mm respectively; when in use, a group of two piston-type particle damping energy dissipation and vibration damping sleepers 1 constitute a complete sleeper; The two piston-type particle damping energy dissipation and vibration damping sleepers 1 in the same group are respectively installed on both sides of the rail to support the two steel rails respectively.

Abstract

The invention discloses a piston-type particle-damping energy-dissipation vibration-reduction sleeper. The piston-type particle-damping energy-dissipation vibration-reduction sleeper comprises a sleeper body and piston-type particle-damping elements buried into the sleeper body; rail bearing grooves are formed in the upper surface of the sleeper body; the piston-type particle-damping elements comprise shells, and damping particles and metal balls are arranged inside the shells; the metal balls are fixedly connected with the sleeper body through metal wires. The piston-type particle-damping energy-dissipation vibration-reduction sleeper has the advantages that the piston-type particle-damping elements arranged inside the sleeper body can absorb and consume vibration energy of the sleeper body; the mode that the piston-type particle-damping elements are buried into the sleeper body is equivalent to the effect of increasing damping of the piston-type particle-damping energy-dissipation vibration-reduction sleeper; the piston-type particle-damping energy-dissipation vibration-reduction sleeper can dissipate vibration energy generated through the wheel rail effect, and the vibration-reduction vibration-isolation effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of rail transit, and specifically relates to a piston-type particle damping energy-consuming and vibration-damping sleeper. Background technique [0002] In recent years, railway and urban rail transit systems have developed rapidly due to their large capacity and environmental protection advantages, but rail transit has the harmful effects of noise and environmental vibration. [0003] Traditional track structure vibration damping technologies include floating plates, damping fasteners, ballast pads, etc. Their working mechanism is to change the rigidity of the track structure to achieve the effect of damping. These devices have high cost or aggravation of the car body. The problem of vibration. Therefore, it is necessary to develop a new type of track structure vibration reduction equipment. Summary of the invention [0004] The purpose of the present invention is to provide a piston-type particle damping energy...
