Vibration damping system with excellent vibration damping in wet conditions

Abstract

The invention provides a vibration absorption system with an excellent vibration absorption effect under a water condition. The vibration absorption system comprises a base cushion and a side cushion, wherein the side cushion comprises a left side cushion and a right side cushion; the left side cushion and the right side cushion are arranged on the left side face and the right face of a track bed plate of a ballastless track respectively; the bed cushion is arranged under the track bed plate and is located above a base; the left side of the base cushion is in tight contact with the bottom surface of the left side cushion; the right side of the base cushion is in tight contact with the bottom surface of the right side cushion; the base cushion is formed by arraying strip-shaped non-vibration-absorption units and vibration absorption units at intervals along a track direction; the vibration absorption units and the non-vibration-absorption units are both made of fully-closed-pore foaming materials. The base cushion is made of the fully-closed-pore foaming material, so that the problem that as the vibration absorption cushion is in an opening / closing pore mixing structure, water easily enters a pore to decay the vibration absorption effect in the prior art is solved, and furthermore, the vibration absorption effect of the vibration absorption system under the water environment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rail vibration reduction, and in particular relates to a vibration reduction system with excellent vibration reduction effect under the condition of water. Background technique [0002] With the development of society, railways and urban rail transit have developed rapidly, and the vibration and noise problems of railways and urban rail transit have become increasingly prominent. If effective measures are not taken, it will not only reduce the comfort of passengers, but also It will shorten the service life of various parts of the vehicle, and at the same time, it will also affect the work and quality of life of residents along the railway, as well as the life of various equipment and buildings. Therefore, it is of great significance to effectively solve the vibration and noise problems of railways and urban rail transit. [0003] The commonly used rail vibration reduction schemes are as follows: [000...

Problems solved by technology

Therefore, in an environment with water, for the above-mentioned first type of elastic damping pad, since it is a mixed structure with open and closed cells, water will enter into the open-pore structure, and only the closed-cell structure can also achieve vibration reduction, thereby causing vibration reduction. The attenuation of the effect; and for the second elastic damping pad mentioned above, in the environment with water, the water will occupy the deformation space of the cone, so that the damping effect is completely lost
