Description
Technical field
The utility model relates to noise reduction technology, particularly relates to a kind of rubber shock absorber for orbit traffic floating board railway roadbed vibrating isolation system.
Background technology
In the vibration and noise reducing means of current urban track traffic industry, because the vibration isolating effect of floating plate railway roadbed vibrating isolation system is ideal, be applicable to the high or special vibration damping location needing higher damping requirements, as hospital, concert hall, museum and precision instrument laboratory etc., be widely applied in track traffic vibration Noise measarement.The core component playing vibration isolating effect in floating plate railway roadbed vibrating isolation system is the flexible member under road bed board, play the effect that supporting railway roadbed bears track structure static load and DYNAMIC LOADING OF DRIVING TRAIN ON BRIDGES on the one hand, the effect that the vibration playing the generation of isolation wheel-rail interaction is on the other hand transmitted to basis.The flexible member of orbit traffic floating board railway roadbed vibrating isolation system is mainly divided into three kinds both at home and abroad at present: rubber pad, steel spring and clad steel spring.
Rubber pad floating plate is bottom road bed board and certain thickness rubber mat plate is laid in side, and compressive strain after utilizing rubber to carry, reaches the object of vibration isolation.Point-like, wire and planar is divided into according to paving mode.Such as Washington, DC rail rapid transit adopts rubber pad floating plate in environment sensitive location, and design intrinsic frequency is 14 ~ 16Hz, and vibration isolating effect is about 13dB, but due to maintenance more difficult, improved afterwards.France's Piccadilly being equipped with quarrel rubber pad floating plate track by location, residential block, obtains certain vibration isolation effect to the extension line of London Airport.China in last century the nineties at Guangzhou Line 1 underground cable transit tunnel application of rubber pad floating plate track, design vibration isolating effect is 10 ~ 15dB, and rubber pad floating plate track is laid in the Hong Kong west railway viaduct location of opening for 2003.Although rubber pad floating plate obtains certain effect in the control of track traffic vibration, but because the construction of rubber pad floating plate is complicated, rubber pad is arranged on bottom road bed board, cannot change and maintenance simultaneously, and the stressed rear main generation compressive strain of rubber pad, vibration isolating effect is lower.Meanwhile, because elastomeric material is under the effect of long-term reciprocating fatigue load, application life is lower, cannot reach the application life identical with metal material, and need often to change, maintenance cost is higher, therefore loses the value of extensive use.
Steel spring floating slab be helical steel springs and damping fluid are encapsulated in sealing housing in form steel spring vibration isolator, steel spring vibration isolator is installed on bottom floating plate, connected with vibration isolator by prefabricated outer sleeve, during vibration isolator carrying, steel spring produces elastic compression distortion, internally-damped liquid consumes vibrational energy, thus plays the effect of separating vibration transmission.Because of construction and maintenance convenient, lower to floating plate thickness requirement, design margin evaluation is high, and effectiveness in vibration suppression is obvious, is the wider high damped products of the application of urban track traffic both at home and abroad at present.What apply steel spring floating slab technology the earliest is Germany, the nineties in last century Berlin subway and Cologne subway adopt steel spring floating slab road bed in environment sensitive location, because of the damping property that it is good, successively in countries use such as the U.S., Britain, Korea S, Canada, Singapore.China applies steel spring floating slab technique functions the earliest and starts from 2000, and case history is Beijing Metro Line 13, adopts side-mounted steel spring floating slab at Xizhimen overhead station.Up to now urban track traffic is applied built-in steel spring floating slab total kilometrage and is about more than 100 and lays a railway track mileage.But because steel spring damping is little, need install damping material additional in addition, therefore volume is comparatively large, takies railway roadbed space.There is obvious standing wave effect in steel spring, poor for high frequency pumping vibration isolating effect.After steel spring physical dimension is determined, performance parameter cannot change, and stiffness variation location can only realize transition by changing vibration isolator interval.Steel spring floating slab track structure involves great expense, the location of only wearing building location and special vibration damping at present under train uses, and the good show of product is uneven, cause harmful competition, the water inlet corrosion inefficacy of part vibration isolator and damping leak, constrain the normal use of steel spring floating slab track vibration-reducing product, directly have influence on the environmental quality that urban track traffic is along the line.
Compound steel spring floating slab adopts helical steel springs and the vulcanization of rubber to form composite elastic bearing, and steel spring surface sticking rubber, is called clad steel spring vibration-isolator.Similar with steel spring floating slab, clad steel spring vibration-isolator is installed on bottom floating plate, is connected with vibration isolator by prefabricated outer sleeve, and during carrying, steel spring produces elastic compression distortion, and rubber part consumes vibrational energy, thus plays the effect of separating vibration transmission.Adopt the floating plate of clad steel spring vibration-isolator only in Shanghai Rail Transit Line 9, No. 2 lines, No. 7 part such as line, No. 10 line location test application.Because of when clad steel spring vibration-isolator carries because steel spring and rubber stiffness differ greatly, cause distortion asynchronous, intrinsic frequency comparatively dense, easy initiating system resonance, vibration isolating effect is poor, and its processing technology and technical level are not approved in the industry, be therefore only confined to use within the scope of Shanghai rail transit test section, make no public appearances so far.
