The specific embodiment
[30] orbital segment in the first embodiment of the invention 2 is shown schematically among Fig. 1.Orbital segment 2 comprises two long rails 4 that are fixed on the sleeper 8.Sleeper 8 comprises single concret block 9 and two flexible support members 10 that are arranged between each track 4 and the concret block 9.
[31] according to convention, the benchmark that long rails 4 is determined as longitudinal direction.
[32] flexible support members 10 is the form of cuboid substantially.In the embodiment shown in fig. 1, their width equals the width of the base portion of track 4 substantially, and their length equals the width of block 9 substantially.
[33] flexible support members 10 is received within the groove 12 in each comfortable block 9.The type of each groove 12 in sectional drawing is wide to be rectangle substantially.The width of each groove 12 and length equal the corresponding width and the length of flexible support members 10 in the embodiment shown in fig. 1 substantially.
[34] for example, flexible support members 10 adhesively is connected to sleeper 8.
[35] each track 4 is coupled to block 9 by track securing member (not shown), and it is any laterally mobile that described track securing member prevents that track from taking place with respect to block 9, and track 4 and block 9 and each flexible support members 10 are fixed together.
[36] in the whole hereinafter explanation, based on the frequency range of being considered (being less than or equal to 250Hz), dynamic rate always is regarded as constant and equals 130% of static rigidity substantially.
[37] the vertical dynamic rate shown in flexible support members 10 formation Fig. 4 models is first elastomeric grades 14 of k1.Each track 4 is modeled into and is suspended on the first end of spring 16 that dynamic rate is k1.The second end of spring 16 is connected to block 9.
[38] the dynamic rate k1 of each flexible support members 10 is between the scope of 120kN/mm to 300kN/mm, and preferably between the scope of 200kN/mm to 300kN/mm.For example, the material that is used for each flexible support members 10 is: rubber, polyurethane, or any other elastomeric material.
[39] sleeper 8 shown in Figure 1 at length is presented in Fig. 2 and 3, and this sleeper comprises the sheath body 20 that is used for admitting block 9, the resilient sleeper-bearing 22 that is arranged in the plane of basic horizontal between block 9 and the sheath body 20 and four elastic inserts 24,26 that are arranged in the plane vertical substantially between block 9 and the sheath body 20.
[40] block 9 is the form of cuboid substantially, and it comprises in fact: an end face 32; The bottom surface 34 of one substantially flat, it rests on this bottom surface; With four side faces 36,38, they are connected end face 32 to the bottom surface 34 by circular edge 44 respectively with oblique angle 46.Side face 36,38 comprises two vertical side faces 36 and two horizontal side faces 38.
[41] each side face 36,38 has lower part 36A, the 38A of substantially flat and top 36B, the 38B of substantially flat, and having mid portion 36C, the 38C of substantially flat, described mid portion interconnects top 36B, the 38B of each lower part 36A, 38A and its correspondence.Vertically top 36B and transversely upwards convergence reciprocally of part 38B.Vertically lower part 36A and transverse lower portion are divided 38A convergence reciprocally downwards.Vertically mid portion 36C and laterally mid portion 38C convergence reciprocally downwards, thus an angle with respect to vertical plane formed, and this angle is greater than the angle that is formed by each corresponding lower part 36A, 38A.
[42] block 9 is selected has king-sized weight.Its weight at 350kg between the scope of 450kg, and preferably at 400kg between the 450kg.The weight of block 9 strengthens by increase hardware in concrete usually.
[43] sheath body 20 is formed by the housing of substantially rigid.Sheath body 20 mainly comprises a bottom 48 and a continuous peripheral frame 50 around bottom 48.
[44] bottom 48 has the rectangular top 52 of a substantially flat.
[45] peripheral frame 50 of sheath body 20 has four plates 54,56.These four plates 54,56 comprise two vertical plate 54 and two horizontal plates 56 that correlate lateral surfaces 38 respectively of vertical surperficial 36 of correlating described block 9 respectively.Each plate 54,56 has inner surface 62,64 separately.Each inner surface 62,64 comprises that shape is the groove seat 66,68 of cuboid substantially, and each groove seat is used for admitting elastic insert 24,26 separately.
[46] groove seat 66,68 is basically parallel to corresponding lower part 36A, the 38A of block 9 side faces 36,38.Each groove seat 66,68 has the rectangle perimeter that is limited by continuous all shoulder 66A, 68A.Each groove seat 66,68 also has essentially identical height and identical length with lower part 36A, the 38A of its connection.
[47] each inner surface 62,64 has top 62A, 64A, and described top is divided into smooth and relative vertical direction inclination, and this gradient is equal to or greater than the corresponding mid portion 36C of block 9 side faces 36,38, the gradient of 38C substantially.The height of top 62A, 64A is basic identical with the height of mid portion 36C, the 38C of the corresponding connection of block 9.
[48] top 62A, the 64A of the inner surface 62,64 of plate 54,56 are connected with the continuous top 70 of frame 50.In the embodiment shown in Fig. 2 and 3, top 70 has two fingers that are used for fixing continuous gasket seal 72.For example, pad 72 is made by natural or synthetic rubber.It implements sealing between block 9 and sheath body 20, and can not stop block 9 moving in sheath body 20.Can also be by will casting with the form of continuous ball such as the material of silicon gum or polyurethane, and obtain gasket seal 72.
[49] rigidity of sheath body 20 strengthens by rib 74, and described rib is formed on the outside of plate 54,56 in the mode of projection, and partly is formed on below the bottom 48.For example, they and sheath body 20 integrally moulded moulding.Adopt prior art, special mode known in EP-A-0 919 666, these ribs 74 can be any suitable shape and the correct position of any relative sheath body 20.In the embodiment shown in Fig. 2 and 3, they have recess 76, and described recess can make sheath body 20 be fixed on the strength member.When carrying out track laying, rib 74 is imbedded in the concrete at least in part.Therefore they be used for sheath body 20 is fixed to fill concrete.
[50] in the embodiment shown in Fig. 2 and 3, sheath body 20 may be made in a moulded piece.In unshowned mode, can make sheath body 20 by a plurality of local housings are fitted together, as disclosed in the prior art (for example EP-A-0 919 066).As the monolithic sleeper 8 in the first embodiment of the invention, for example they can comprise that two each half housings and one in each end interconnect the middle casing of two end half housings.
[51] for example, sheath body 20 is made by the molding thermoplastic material or by resin concrete.
[52] resilient sleeper-bearing 22 is the form of cuboid substantially, and it has the end face and the bottom surface of substantially flat, so that the mechanical stress that resilient sleeper-bearing 22 is born is reduced to minimum and avoided fatigue problem.Its length and width equal the length and the width of the bottom surface 34 of block 9 respectively substantially.
[53] its thickness is between 10 millimeters (mm) to 20 millimeters (mm), preferably at 16mm between the 20mm.Therefore resilient sleeper-bearing 22 remains in the elastic range; It corresponds essentially to and is less than or equal to 40% maximum deformation quantity.Deflection is the ratio of the varied in thickness of resilient sleeper-bearing 22 between free state and loaded-up condition.
[54] the vertical dynamic rate of resilient sleeper-bearing 22 formation as shown in Fig. 4 model is second elastomeric grades 78 of k2.On the first end of the spring 80 that rigid block movement 9 is modeled into and is suspended on two dynamic rates is k2.The second end of spring 80 is connected to sheath body 20.
[55] dynamic rate of the device that uses less than tradition of the dynamic rate k2 that has of resilient sleeper-bearing 22 of the present invention.Dynamic rate k2 at 6kN/mm between the 10kN/mm, and preferably at 6kN/mm between the 8kN/mm.
[56] for example, resilient sleeper-bearing 22 is made by porous elastic material.
[57] in a preferred embodiment, the vertical dynamic rate k2 of resilient sleeper-bearing 22 basically identical on its whole zone.
[58] in another embodiment, resilient sleeper-bearing 22 is less than or equal to k2 at the vertical dynamic rate k3 of the zone line of block 9.Zone line comprises the middle part of block 9, and laterally extends on basic half the zone of described block 9 towards the end from each side at block 9 middle parts.Because this zone line is subjected to stress less, thereby may use more full of elasticity therein and so more cheap material.
[59] resilient sleeper-bearing 22 can freely rest on the bottom 48 of sheath body 20.Therefore it can easily be removed from sheath body 20.
[60] advantageously, sleeper 8 also has incompressible substantially thickness member 82, as shown in Fig. 2 and 3.
[61] thickness member 82 is the form of cuboid substantially.Its length and width equal the length and the width of the end face 52 of sheath body 20 bottoms 48 substantially.Its thickness is less than or equal to 10mm, and preferably at 2mm between the 4mm.
[62] thickness member 82 freely rests on the bottom 48 of sheath body 20.Therefore can easily remove it from sheath body 20, perhaps it can be added on the sheath body 20, so that the planarization of adjustable track.
[63] advantageously, resilient sleeper-bearing 22 freely is bearing on the thickness member 82.
[64] surface of thickness member 82 is enough coarse to avoid resilient sleeper-bearing 22 to slide in sheath body 20.For example, this roughness obtains by sawtooth, rhombus point or hangnail.
[65] each elastic insert 24,26 has an external surface 24A, 26A and an inner surface 24B, 26B and four side faces.
[66] basic identical and their profile of the size of external surface 24A, 26A and inner surface 24B, 26B is rectangle substantially.
[67] length of external surface 24A, 26A and inner surface 24B, 26B and width equal the length and the width of the corresponding groove seat 66,68 in the peripheral frame 50 of sheath body 20 respectively substantially.
[68] elastic insert 24,26 is in the face of in corresponding groove seat 66,68.For example, they are held by the frictional force between all shoulder 66A, the 68A of the side face of elastic insert 24,26 and each groove seat 66,68.Therefore elastic insert 24,26 can easily be removed.
[69] each elastic insert 24,26 also can be held by buckle.For example, groove seat 66,68 can have groove and elastic insert 24,26 can have complementary groove.
[70] thickness of elastic insert 24,26 is greater than the thickness of groove seat 66,68, thereby their relative shoulder 66A, 68A protrude.
[71] inner surface 24B, 26B are only pressing correspondence bottom branch 36A, the 38A of the side face 36,38 of rigid block movement 9.
[72] as shown in Fig. 2 and 3, inner surface 24B, 26B are equipped with groove, thereby have increased their pliability.
[73] dynamic rate of elastic insert 24,26 at 12kN/mm between the 25kN/mm.For example, they can be made by rubber, polyurethane or any other elastomeric material.
[74] power that is subjected to corresponding to vertical vertical liner 24 of side face 36 is greater than the power that is subjected to corresponding to the horizontal horizontal liner 26 of side face 38.Therefore advantageously, vertically liner 24 may be selected to the dynamic rate of its dynamic rate greater than horizontal liner 26.Therefore for example, vertically liner 24 has between 20kN/mm to the dynamic rate between the 25kN/mm, and laterally liner 26 has between 15kN/mm to the dynamic rate between the 18kN/mm.
[75] under normal operation, elastic insert 24,26 keeps block 9 to leave the inner surface 62,64 of sheath body 20.
[76] therefore elastic insert 24,26 provides the level buffering for block 9.This level buffering is separated with the vertical buffering that obtains by flexible support members 10 and resilient sleeper-bearing 22.
[77] should observe: the quantity of elastic insert is unqualified.For example, sleeper 8 can have two horizontal liners 34 side by side in each side of block 9.
[78] Fig. 5 sleeper that prior art is shown and acoustical behavior according to sleeper of the present invention.Fig. 5 illustrates the function of insertion gain as frequency.Insertion gain in this embodiment is the ratio between value (speed, acceleration, pressure etc.) tested when comprising resilient sleeper-bearing and the value that obtains when not comprising resilient sleeper-bearing, and this ratio is by decibel (dB) expression (referring to French Standard ISO14837-1:2005).In described embodiment, this is the power that is applied on the sheath body 20.The minimizing of value (value of the magnitude) is represented by the insertion gain of band negative sign.
[79] in addition, cut-off frequency is such frequency: can be observed insertion gain when surpassing this frequency and reducing.
[80] k1dyn is the dynamic rate of flexible support members 10, and k2dyn is the dynamic rate of resilient sleeper-bearing 22, and M is the weight of block 9.
[81] the expression insertion gain is the curve of the function of frequency---wherein: every meter of k2dyn=21.3 meganewton (MN/m), M=200kg and k1dyn=150MN/m---constitute to show prior art performance with reference to curve S 1.Second curve is represented sleeper performance of the present invention, k2dyn=8MN/m wherein, M=400kg, and k1dyn=270MN/m.
[82] arrive in the scope of 10Hz 0, the vibration attenuation performance is basic identical.In the scope of 25Hz, insertion gain is compared with curve S 1 bigger a little decibel (dB) at 10Hz.In the scope of 250Hz, insertion gain is wanted decimal decibel (dB) than curve S 1 at 25Hz.
[83] in addition, cut-off frequency is lower than the cut-off frequency (the former is 20Hz rather than 32Hz) of curve S 1.
[84] therefore, in the scope of 250Hz, the performance of sleeper of the present invention is obviously outstanding at 25Hz.
[85] in second embodiment shown in Figure 6, sleeper 108 comprises two by the rigid block movement 109 of a support every device 184 interconnection.Because the sleeper 108 of two block formulas is very similar to single block formula sleeper 8, thus in Fig. 6, use with Fig. 1 to 4 in the identical mark of used mark, but add 100.
[86] length of sheath body 120 is suitable for admitting block 109.Same content application is in horizontal liner 126 and resilient sleeper-bearing 122.The Fig. 2 and 3 that shows single block formula sleeper 8 also can be applicable to represent sleeper 108 fully.
[87] main distinction between single block formula sleeper 8 and the two block formula sleepers 108 is: exist one to penetrate two supports in the block 109 every device 184.
[88] reducing and/or the increase of block 109 weight of the dynamic rate k2 of resilient sleeper-bearing 122 produces big buckling and moves.
[89] therefore, support is suitable for obtaining big second area moment every the shape of device 184.For example, it can be the form of angle section or cylinder barrel.For example, support has at 800 square millimeters of (mm every device 184
2) basal area in 1500 square millimeters of scopes, and its thickness at 6mm between the 10mm.For example, it is made by the steel that meets standard EN 13230-3.
[90] weight of each block 109 at 100kg between the 150kg, preferably at 130kg between the 150kg.
[91] should observe: single block formula sleeper 8 is good at keeping out the extra mechanical stress that the present invention causes especially.
[92] be to be understood that: for sleeper of the present invention, the dynamic rate k2 of resilient sleeper-bearing 22,122 reduces to be used to obtain better vibration attenuation performance, particularly by reducing cut-off frequency and reducing insertion gain at 25Hz between the 250Hz.
[93] for the given dynamic rate k2 of resilient sleeper-bearing 22,122, the increase of block 9,109 weight also can reduce cut-off frequency, and therefore can improve the performance of sleeper 8,108 in low frequency.Yet more than constant weight, the mechanical stress that sleeper 8,108 bears will become too big.
[94] increase of the dynamic rate k1 of flexible support members 10,110 has reduced the insertion gain between the 250Hz scope at 200Hz, and makes the frequency shifts of resonance frequency Chao Genggao, and resonance frequency to be insertion gain be observed the frequency that increases.
[95] the present invention therefore can near utilize cut-off frequency at 14Hz between the 20Hz and the vibration attenuation performance that obtains for the floating slab of-25dB at the 63Hz place of insertion gain.
