Abstract

The invention relates to a vibration damping sleeper using a periodic structure to consume energy. The vibration damping sleeper comprises a sleeper body (1) and an energy-consuming part (3), whereinthe energy-consuming part (3) is arranged in the sleeper body (1). The energy-consuming part (3) is cube blocks formed by stacking a plurality of energy-consuming blocks in a multi-layer mode, and each layer of the cube blocks is composed of the corresponding energy-consuming blocks. The energy-consuming blocks include mass blocks (31) and elastic blocks (32), and the arbitrary mass block (31) isnot adjacent to the corresponding elastic block (32). Compared with the prior art, the vibration damping sleeper using the periodic structure to consume the energy has the advantages of a simple preparation process, low cost and excellent vibration damping performance.

Description

technical field [0001] The invention relates to a vibration-damping sleeper technology in the field of rail transportation, in particular to a vibration-damping sleeper utilizing a periodic structure to consume energy. Background technique [0002] With the massive construction of urban rail transit, more and more rail transit lines are close to or even pass through buildings that require vibration control, such as hospitals and scientific research institutions with high-precision instruments, and ancient buildings that need special protection. The requirements for high smoothness and high stability of the track are becoming more and more stringent. At present, a large number of damping fasteners and damping tracks have been put into application. As the sleeper is an important part of the track structure, the development of the sleeper with the function of vibration reduction will be one of the important research directions. [0003] CN201310545276.3 discloses a railway sl...
