Abstract
Disclosed is a low rigidity high elastic vibration reduction liner plate. Bidirectional arc or trapezoid grooves mutually perpendicular to each other are arranged on the upper surface and the lower surface of a body, consequently a plurality of convex blocks with square surfaces are evenly distributed on the upper and the lower surfaces of the body, the upper and the lower convex blocks are mutually dislocated, and four side surfaces of each convex block are groove walls of the grooves. With an action of dynamic forces, a high resiliency is mainly achieved through deflection and deformation, a dynamic or a static rigidity ratio is small, an elastic restitution speed is comparatively quick, rigidities of liner plates are capable of being changed through changes of groove widths, depths and spaces between grooves, low rigidity high-elastic vibration reduction liner plates with different static and dynamic rigidities can be made of polymer materials with comparatively high flexural modulus, and excellent comprehensive performances such as a high elasticity, a high bearing capacity, good vibration reduction effects and a long service life can be achieved.
Description
Technical field
The utility model relates to the high-elastic vibration attenuation pad of a kind of vibration damping, relates in particular in a kind of track traffic the high-elastic vibration attenuation pad of employed low rigidity in the rail clip system.
Background technology
Along with The development in society and economy, urban rail transit construction is densification and high speed more and more, and the laying of ballastless track overhead railway and application are also more and more wider.So how to reduce track vibration and noise, the good ground that improves is coordinated mutually with nature and living environment, just becomes the problem that people receive much concern.
The most economical effective method that reduces track vibration and noise level is the rigidity that reduces rail support point, improves its elasticity.Reduce the rigidity of resilient sleeper-bearing in the rail clip system, improve its elasticity resume speed, then can reduce the rigidity of rail support point effectively, reduce the amplitude level of the power of transmitting and reduce vibration environment damage.
The low rigidity rubber mat plate commonly used at present or the shortcoming of the equal various degrees of the high-elastic backing plate of polyester elastomer.Low rigidity rubber mat plate is soft excessively, and it is slower that deformation recovers, moving/quiet ratio of rigidity is bigger, and fatigue performance is bad; Though the high-elastic backing plate of polyester elastomer can utilize deflection and compressive deformation simultaneously, both provide elasticity simultaneously, and it is very fast that deformation recovers, and because of its structure is unidirectional upper and lower surface dislocation groove structure, make backing plate have stronger anisotropy.Particularly under the effect of vertical force, transverse deformation amount along the groove direction is less, deformation quantity perpendicular to the groove direction is bigger, and the result makes that the active force of backing plate contacting piece different directions is unbalanced, can influence the comprehensive result of use of fastener system to a certain extent.
The utility model content
The purpose of this utility model is to provide a kind of low rigidity high-elastic vibration attenuation pad, because its special structure, can make backing plate mainly provide screen resilience by flexural deformations, and quiet rigidity is low, good springiness, sound ratio of rigidity are little, and rebound velocity is very fast; And under the effect of vertical force,, can give full play to the resultant effect of fastener system, thereby make rail support put elastification more and low rigidityization along the rail direction with perpendicular to the transverse deformation amount equilibrium of rail direction.
To achieve the above object, the high-elastic vibration attenuation pad of low rigidity that the utility model provides adopts two-way groove structure, it is characterized in that: on the body upper and lower faces, be formed with an irregular body, this irregular body is orthogonal two-way arch groove, it also can be trapezoidal groove, the upper and lower faces mutual dislocation, making it to form many surfaces on body is square projections, be evenly distributed in the upper and lower faces of body, and upper and lower mutual dislocation, four cell walls that the side is a groove of projection.Under the effect of vertical force, mainly provide high screen resilience by flexural deformations.After laying down active force, deformation recovers rapidly.
The high-elastic vibration attenuation pad of low rigidity that the utility model provides is a kind of brand-new elastic model, its quiet rigidity and dynamic stiffness can be by changing groove the size of width, the degree of depth and separation and the modulus of material therefor change, can produce the low high-elastic vibration attenuation pad of rigidity with macromolecular material with higher bending modulus, the supporting capacity and the fatigue performance of backing plate have been improved, make it to have good comprehensive functional performance, its characteristics are as follows:
1. low rigidity, high resiliency, high bearing capacity, high effectiveness in vibration suppression
2. low moving/quiet ratio of rigidity makes sleeper, roadbed and destruction of bridge reduce to minimum
3. reduce the maintenance, repair workload
4. long application life (can be more than the twice of rubber mat plate)
5. losing efficacy backing plate can recycling, helps environmental protection
