Description
Technical field
The utility model relates to damping shock absorber, particularly a kind of ripple struction damping shock absorber being applicable to support railway track, track plates etc.
Background technique
Rubber absorber, as rubber arthrosis, rubber metal pad, rubber pad, neoprene bearing etc., because its rigidity easily adjusts, good damping result, easily obtains the advantages such as larger resiliently deformable, lightweight, easy maintenance, be widely applied in the installations and facilities such as railway vehicle, track, building structure, bridge, rubber-like damping element commonly used by railroad track under the rubber mat plate of fastener system, track plates rubber metal pad vibration damper etc. under rubber mat plate and track plates, be mainly used to wheel-rail force of decaying, and Transmit evenly is to basic construct thing under the lines such as roadbed or bridge tunnel.At present, rail fastener system adopt rubber mat plate and track plates under rubber mat plate vibration damping Method compare single, mainly by its pressure elasticity distortion reach energy storage and the function of energy-absorbing.Germany clone egg shape fastener system is become by the shearing of rubber elastic material provides elasticity, vertical stiffness is low, springrate ratio is little, damping property is more superior compared with compressive strain mode, can simultaneously for rail provide vertical, the elastic support of transverse direction, longitudinally three directions.Under the track plates of Korea S RMS company designs, rubber shock absorber (HLRM) is on the basis making full use of this mode of rubber elasticity distortion energy-obsorbing and damping, utilize the shearing friction effect between circular cone oblique rubber interface, play the effect of a double mode vibration damping.
From mechanics principle, track structure can be considered mass-spring-damper system, upwards be used for providing a smooth-going operation supporting surface to train operation, be used for downwards dynamic action between wheel and rail being decayed and being passed to basis, therefore, track structure is just had to the requirement of two kinds of functions, namely good smoothness and damping property, according to single-degree-of-freedom vibration attenuation mechanism, system will have more excellent damping property, and so its support stiffness must be lower, but, lower support stiffness will cause rail level displacement excessive, and then bring the hidden danger affecting safe train operation.Therefore research is a kind of can absorb more vibrational energies, but does not cause the vibration damper of over-large displacement, is the difficult problem that railroad track vibration damping faces.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of ripple struction damping shock absorber, has better effectiveness in vibration suppression to make vibration damper when more thin tail sheep.
It is as follows that the utility model solves the technological scheme that its technical problem adopts:
Ripple struction damping shock absorber of the present utility model, it is characterized in that: it comprises at least one deck sheet metal and makes skeleton, the plate face of skeleton is continuous shape ripple or zigzag fashion interval ripple, arranges the elastic filler with elasticity and damping characteristic in the groove that ripple is formed.
The beneficial effects of the utility model are, under the effect of outer load, the shear-compression deformation passive energy dissipation of elastic filler, friction energy-dissipating vibration damping and skeleton distortion vibration damping planar between elastic filler and skeleton, make it have triple vibration damping mode, vibration damper can be made just to realize more excellent good effectiveness in vibration suppression with less displacement, and there is good impact property, existing rubber tie plate under rail can be replaced; Skeleton ripple struction produces the deformation that laterally runs on a bank when bearing the vertical force of rail, carry out a buffering, play good effectiveness in vibration suppression to vertical force; Elastic damping object is made up of the material with elasticity and damping characteristic, has significantly buffering absorbing effect for the vertical force from rail, and its deformation in skeleton, also has good effectiveness in vibration suppression simultaneously.
The utility model be applicable to very much being applied in operating space narrow and small, in the high particular surroundings of load damping requirements, relative to conventional helical coil spring vibration damper, under identical loading condition, compression height of the present utility model is only 30 ~ 50% of Cylindrical spiral spring vibration damper, by triple vibration damping mode, under can be implemented in the prerequisite of identical track structure displacement, make the 1 rank natural frequency of the track structure acquisition 5 ~ 10Hz adopting the utility model as vibration damper under plate, reach more excellent effectiveness in vibration suppression.In like manner, adopt the utility model as the track structure of vibration damper under plate with other types vibration damping type track structure under the prerequisite keeping identical natural frequency, the displacement that can realize track structure reduces 30 ~ 50% compared with the displacement of other vibration damping type track structures, improves safety in operation and the riding comfort of train.

Component name shown in figure and corresponding mark: skeleton 10, groove 11, elastic filler 20.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Referring to figs. 1 through Fig. 6, ripple struction damping shock absorber of the present utility model comprises at least one deck sheet metal and makes skeleton 10, the plate face of skeleton 10 is continuous shape ripple or zigzag fashion interval ripple, arranges the elastic filler 20 with elasticity and damping characteristic in the groove 11 that ripple is formed.
Under the effect of outer load, the shear-compression deformation passive energy dissipation of elastic filler 20, friction energy-dissipating vibration damping and skeleton 10 distortion vibration damping planar between elastic filler 20 and skeleton 10, make it have triple vibration damping mode, vibration damper can be made just to realize more excellent good effectiveness in vibration suppression with less displacement, and there is good impact property, existing rubber tie plate under rail can be replaced.In addition, the ripple struction of skeleton 10 produces the deformation that laterally runs on a bank when bearing the vertical force of rail, carry out a buffering, can play good effectiveness in vibration suppression to vertical force.Elastic filler 20 is made up of the material with elasticity and damping characteristic, has significantly buffering absorbing effect for the vertical force from rail, and its deformation in skeleton 10, also has good effectiveness in vibration suppression simultaneously.
The utility model be applicable to very much being applied in operating space narrow and small, in the high particular surroundings of load damping requirements, relative to conventional helical coil spring vibration damper, under identical loading condition, compression height of the present utility model is only 30 ~ 50% of Cylindrical spiral spring vibration damper, by triple vibration damping mode, under can be implemented in the prerequisite of identical track structure displacement, make the 1 rank natural frequency of the track structure acquisition 5 ~ 10Hz adopting the utility model as vibration damper under plate, reach more excellent effectiveness in vibration suppression.In like manner, adopt the utility model as the track structure of vibration damper under plate with other types vibration damping type track structure under the prerequisite keeping identical natural frequency, the displacement that can realize track structure reduces 30 ~ 50% compared with the displacement of other vibration damping type track structures, improves safety in operation and the riding comfort of train.
