Definitions

  • the invention relates in particular to the problem of acoustic and anti-vibration insulation of railways installed on roads.
  • the inventors set out to analyze the static behavior and the dynamic behavior of the railway track when a vehicle passes over the rails.
  • a car traveling on the rails produces two impacts on the rails. The first is due to the mass of all the cars in the train: it is the static load transferred to the bogies; the second impact is due to the mass not suspended from the bogie: it is this mass which produces the dynamic impulses by the wheels on the rails and it is these impulses which are transmitted towards the environment.
  • the first flexural resonance frequency of the wheel / rail assembly is conditioned by the dynamic stiffness of the soles placed under the rails and, if necessary, by that of the cushions placed under the saddles or crosspieces.
  • This resonant frequency is inversely proportional to the anti-vibration performance of the rail fastening system.
  • a low resonant frequency provides better vibration isolation than a high resonant frequency.
  • Insulation performance Better antivibration is obtained by decoupling the fixing function and the insulation function.
  • separating elements consisting of prefabricated elements or of a waterproof and flexible filling product, are chosen so that the static and dynamic stiffnesses of the assembly are less than those of the flanges placed under the pads of the rails.
  • the rails are thus completely independent of the roads, which has the consequence of considerably reducing the transmission of vibrations to the foundations of neighboring buildings at the same time as sealing is ensured along the rails.
  • a system in which the rail is coated with a very compact resilient material to give it better mechanical resistance to expansion and to the forces generated by the movement of cars on the rail does not have the static and dynamic characteristics required to ensure effective vibration isolation and, therefore, the transmission of vibration waves to the foundations of neighboring buildings is maximum.
  • the rails can be fixed to the slab slab in different ways: by means of saddles or crosspieces or even by direct laying on the slab slab. Under the pad of each rail is usually interposed a rigid or anti-vibration sole. Often below and underneath each saddle or cross member is an anti-vibration pad.
  • the slab slab has bowls to receive the lower part of the sleepers.
  • the slab slab 15 rests on a layer of stabilized sand 17 placed on the bottom of the trunk (ground) 19.
  • a draining layer 16 intended to drain water infiltration towards draining pipes 18 arranged at intervals along the track with a diameter and a spacing which are a function of the geographical location of the road.
  • the slab slab ensures the stability of the installation.
  • a layer of anti-vibration material can also be placed between the stabilized sand bed and the slab slab.
  • the vacuum between the road slab 22 and the slab slab 15 is preferably filled by injection of a suitable filling product 28 chosen according to the degree of insulation required by the environment.
  • the successive supports along the track are made so as to alternately constitute a support relatively rigid and relatively flexible support.
  • FIG. 4 illustrates a case where the rail 11 is fixed to saddles 33 sealed in the slab slab 15, using an epoxy mortar, for example.
  • the reference 31 designates a device for fixing a rail with joint bars.
  • On the stabilized sand 17 are arranged, for example, a draining layer 35 and an anti-vibration isolation mat 37.
  • the spaces between each rail 11 and the road slabs 21 and 22 are filled with separation elements 25 made of material having predetermined static and dynamic rigidities.
  • FIG. 7 illustrates the fixing of a rail 11 on a saddle 43 which is itself fixed to the slab slab 15 by means of an adjustable fixing device 41 applying an adjustable preload to the anti-vibration sole 42 disposed under the saddle 43
  • This fixing device provides antivibration isolation at low resonance frequency.
  • the fixing device illustrated comprises a prestressing spring 45 held between two abutment washers around a threaded rod 44.
  • the spring 45 is compressed by the clamping nut 46 which adjusts the prestressing force.
  • the fixing device may also include two springs having rigidities different and held between two washers around the threaded rod 44, the springs being compressed by the clamping nut 46 which adjusts the prestressing force.
  • the inventors have devised a measurement method by which the effects of the total static load applied to an axle of a vehicle having to travel on a railway track are decoupled from the equivalent of the unsprung mass of a bogie.
  • the implementation of this method can be carried out, for example, using a test bench as shown diagrammatically in FIG. 9.
  • the supports 61 are produced with static and dynamic stiffness chosen according to the actual operating conditions and the desired level of performance. For example, in the case where it is desired to optimize the antivibration isolation and limit the deflection of the rail, the supports 61 will be produced with alternating stiffnesses so as to be alternately a relatively rigid support R and a relatively flexible support S.
  • load cell 64 By applying to load cell 64, a load in stages ranging from 0 to 250 kN, for example, and by moving the carriage along the section of track, it is possible to detect the static deflection of the rail to the right of each support.
  • the natural frequency of the track system can be noted, the deflections in line with the supports and vibration damping of the rails to the right of each support.
  • the analyzes thus carried out allow the designer of a railway track to be installed to determine in an optimal manner the particularities of the acoustic and anti-vibration insulation elements to be incorporated in the railroad support system in order to optimize the acoustic and anti-vibration insulation. and reduce the transmission of vibration waves to the environment.
