Background technique
Traditional rail damper mostly uses dynamic vibration absorber DVA (Dynamic Vibration Absorber) structure, such as
Shown in Fig. 1.Its chief component includes elasticity-damping unit and mass unit.
It is using principle: the intrinsic frequency of rail damper and rail itself vibration natural frequency are close or are overlapped, when
When frequency range of the rail near its intrinsic frequency is vibrated, " mass-spring-damper " system and steel that rail damper is formed
Rail forms reversed resonance, to reduce the vibration of rail, absorbs the vibrational energy of rail.It is hindered using dynamic vibration absorber structure rail
The advantages of Buddhist nun's device is that it can carry out design for specific rail intrinsic frequency, and shock attenuation result is good, and optimal cases are can to incite somebody to action
Rail is reduced in the vibration of its intrinsic frequency close to zero.However the rail damper of dynamic vibration absorber structure is used also to have one
A fatal disadvantage: the vibration damping frequency band of rail damper is very narrow, intrinsic frequency must near the intrinsic frequency of rail, if
Intrinsic frequency of the intrinsic frequency of rail damper far from rail, will be unable to form antiresonance effect, and what can be played " inhales
Vibration " effect will be very limited.
Generally, when rail damper product specific structure once fixed, its own characteristics of mode (intrinsic frequency and
The vibration shape) it can not just change, just it can only play the role of dynamic absorber for specific rail vibration frequency.
In actual application, the duty parameter of different routes is different, as fastener rigidity, fastener branch tie distance,
Ballast rigidity, route curve radius, train running speed, train model etc..And different duty parameters the problem of bringing is not
Vibration natural frequency with rail is different.If used on different routes with identical product, it may appear that because rail hinders
The intrinsic frequency and the inconsistent situation of rail vibration intrinsic frequency of Buddhist nun's device are difficult to play the absorbing effect of rail damper in this way
Fruit.In addition, as the railroad embankment time limit increases, the duty parameter of track can change (such as: for a long time using in rear fastener
Aging occurs for elastic element, and rigidity can change) vibration natural frequency that will also result in rail changes, originally inherently
The matched rail damper of frequency will be no longer applicable in, and effect of vibration and noise reduction can be deteriorated.
In view of this, proposing the present invention.
