Description
Technical field
The present invention relates to track traffic vibration control field, more particularly, to a kind of Hierarchical Track plate of embedded energy-consuming device
Structure.
Background technology
As the communications and transportation pattern of most sustainability, track traffic is the main artery of Chinese national economy, to the modern times
Urban construction and social development play supporting role of overall importance.However, the fast development of track traffic is made an uproar with vibration all the time
Sound problem, drastically influence citizen's daily life.Related construction department and designing unit input substantial contribution and manpower, it is progressively complete
Kind vibration damping track, to meet vibration control demand.No. 12 line Damping fastening circuits of Shanghai Underground account for overall length 17.5%, high
Level floating plate rail structure accounts for 21.3%, and No. 13 line one phase vibration damping sections account for bus ratio and are up to 57%.No. 4 lines of Beijing Metro and
No. 5 line vibration damping circuits account for overall length 31% and 53% respectively.In tier 2 cities, as Ningbo Line 2 Metro one phase vibration damping section accounts for entirely
Long 50%, No. 82, No. 3 line second phases of Harbin subway, Qingdao region line vibration damping sections account for total length ratio more than 42%.
Urban rail transit in China vibration reducing measure can divide high, medium and common damper rail by vibration damping grade.It is high-grade
Damper rail is mainly floating plate track, including distributed, wire type or integral rubber floating plate or steel spring floating slab structure,
Effectiveness in vibration suppression is more than 15dB, reaches as high as 35dB；Medium damper rail mainly includes pioneer's fastener, elastic short rail sleeper and long rail
Pillow, ladder-type sleepers etc., effectiveness in vibration suppression are about 10~15dB；Common damper rail mainly uses all kinds of spring secures rail to sleepers, highest vibration damping
Effect is up to 10dB.
Although the optimization of above-mentioned different brackets vibration damping track and perfect, track traffic vibration and noise reducing is set to achieve noticeable achievement.
But for now, however it remains insurmountable problem and gradually exposed new problem.For example the existing vibration damping of track traffic is arranged
The overwhelming majority is applied using classical theory of vibration isolation, i.e., vibrational energy is effectively isolated using mass-spring system, makes it downward
Transmit along the line.More and more theoretical and experimental studies show, are provided with the damper rail of middle and high grade vibration isolation measure
Vibrational energy is gathered in rail superior portion structure, and the machinery of rail and wheel and parts is easier to relative to common solid concrete roabed
Disease.Secondly, internal car noise problem getting worse gradually exposed in high-grade damper rail, especially underground line, a side
Face track plates and rail vibration are transferred to car body by vehicle suspension system and make an uproar and then to in-car radiated noise, another aspect wheel track
Low frequency configuration noise is transferred to guest room and drivers' cab in the form of direct sound wave or transmission sound in sound and tunnel.Cause the above problem
Basic reason be, although the vibration isolation measure such as high resiliency fastener, floating plate track can effectively weigh system capacity
New distribution, can not but be consumed, thus the track circuit of application super-elasticity fastener system is easier to the diseases such as rail corrugation occur
Evil, high-grade floating plate part of path internal car noise are relatively more notable.In addition, to meet track structure intensity requirement, elasticity member
Part rigidity characteristic parameter causes most vibration isolation measure helpless to low-frequency range all the time, particularly with general with lower limit requirement
Logical grade and medium vibration isolation measure, less than its free frequency vibrational energy can be still transferred to by track and foundation structure along
Building, triggers vibration and quadratic noise problem.
In addition to the above-mentioned track structure vibration isolation measure based on theory of vibration isolation, rail tuner-type vibration absorber utilizes tuning
The inertia force of mass block offsets the wheel track load under characteristic frequency, to improve the method for track structure vibratory response characteristic；Damping
The damping energy dissipation devices such as rail, spliced energy-absorbing track plates are mainly absorbed using the consumption of the macromolecule visco-elastic damping materials such as rubber
Vibrational energy, achievees the purpose that vibration and noise reducing.However, though tuned mass damper and damping steel rail can effectively offset wheel track excitation
Or rail vibration energy is absorbed, but only remarkable effect is played in relatively narrow design frequency domain.Spliced energy-absorbing elastic roadbed passes through
Splice what surface spraying damping material, absorption vibrational energy, but sprayed damping material volume and upper and lower plates deformed in road bed board
Asynchronism is limited, limits energy absorbing efficiency to a certain extent.
