  • the sound absorbing material 14 is provided on the inner plate 2b2 side of the roof structure 2b, and the sound absorbing material 14 is covered with the interior panel 7.
  • aerodynamic noise is generated by the air on the roof of the railway vehicle running at high speed being disturbed, and the aerodynamic noise increases abruptly as the vehicle speed increases, so that the air conditioner 5 and the current collector 6 become large noise sources especially when the train runs at high speed.
  • the aerodynamic noise generated on the roof is transmitted through the roof structure 2a or 2b, the sound absorbing material 14, the interior panel 7, the top plate 8a of the air-conditioning duct, and the like, and is transmitted to the vehicle interior, thereby being a factor that increases the vehicle interior noise.
  • the aerodynamic noise has a relatively large low frequency component, and the sound insulation characteristics of the vehicle body and the sound absorption characteristics of the vehicle interior space are generally low in the low frequency range. Therefore, it is common to take measures against noise on the premise that a low frequency range of 1 kHz or less is dominant in vehicle interior noise. In other words, it is particularly important to improve the sound insulation performance in a low frequency range.
  • an opening 8c for blowing the air-conditioned air into the vehicle interior is provided on a side surface 8b of the air-conditioning duct 8.

  • FIG. 8 is a schematic diagram illustrating a change in transmission loss when the thickness of the sound absorbing heat insulating material having an air layer is changed.
  • the double skin structure is generally lightweight and highly rigid, the natural frequency of the bending mode of the plate exists at a relatively high frequency, and at low frequencies not more than 1 kHz, the primary vibration mode with a long wavelength (see FIG. 5 ) or the secondary vibration mode (see FIG. 6 ) is dominant.
  • the outer plate 2a1, the inner plate 2a2, and the connection plate 2a3, which form a double skin structure vibrate integrally. Therefore, at low frequencies, the double skin structure can be regarded as a single plate, and the laminated structure of the double skin structure, the sound absorbing material 14, and the interior panel 7 can be considered as a double wall structure (see FIG. 7 ).
  • FIG. 7 shows an equivalent rigid plate 2a' to replace the double skin structure.
  • the transmission loss as an index of the sound insulation performance is improved as compared with the mass law.
  • the transmission loss falls below the mass law near the low frequency resonance frequency frL on the contrary, due to the resonance phenomenon in which the equivalent rigid plate 2a' and the interior panel 7 serve as mass and the air layer (equivalent to the space 15) being a medium of the sound absorbing material 14 serves as a spring.
  • the high frequency resonance frequency frH when the thickness of the air layer is increased, the high frequency resonance frequency frH also shifts to the low frequency side.
  • the high frequency resonance frequency frH exists in a high frequency range of not less than 1 kHz, and in such a high frequency range, noise is sufficiently attenuated by the sound absorbing performance due to the sound absorbing material 14, the seat 11 in the vehicle interior space, and the like, so that the shift of the high frequency resonance frequency frH does not normally come to a problem.

  • the thickness dimension t of the space 15 is approximately three times or less with respect to the structure thickness L (also simply referred to as the thickness) of the double skin structure (t ⁇ 3L) exhibits a significant effect. It should be noted that it is more preferable that t ⁇ 2L.
  • the railway vehicle of the present embodiment is provided with the air conditioner 5 or the current collector 6 on the roof, and therefore has a large dimensional constraint in the ceiling height direction, so that there is an actual situation that the thickness of the sound absorbing material 14 cannot be sufficiently secured.
  • the sound absorbing material 14 it is particularly effective to provide a hole 16.
  • making holes in the inner plate 2a2 or 2b2 of the roof structure 2a or 2b increases the transmission loss and improves the sound insulation performance, so that the transmission of aerodynamic noise generated by the air conditioner 5 or the current collector 6 on the roof into the vehicle interior is reduced.

  • a plurality of holes 16 penetrating the inner plate 2b2 along the X direction are drilled at positions between the connection portions between the face plate (inner plate) 2b2 on the vehicle interior side and the connection plates 2b3 in the double skin structure.
  • the vehicle interior side cavity 17 surrounded by the inner plate 2b2 and the connection plates 2b3 of the double skin structure communicates with the space 15 through the holes 16, and the compressional wave of the sound wave transmitted through a double skin structure DS can also enter the vehicle interior side cavity 17.
  • providing the holes 16 increases the thickness t of the space 15 by the structure thickness L of the double skin structure DS, that is, the effect such that the thickness increases to (t + L) is obtained.
  • Communicating the space 15 with the vehicle interior side cavity 17 inside the double skin structure DS causes the mechanism of improving sound insulation performance in the present arrangement to exert the same effect as when the thickness of the space 15 is increased. Therefore, drilling only a minimum necessary number of holes with as large diameter as possible is more excellent in sound insulation performance than drilling a large number of holes with small diameter, and is also preferable from the viewpoint of preventing an increase in the number of manufacturing steps due to hole drilling.
  • the inner diameter d of the hole 16 be approximately in a range where (P/5) ⁇ d ⁇ (4P/5) with respect to the interval of the connection portions between the inner plate 2b2 and the connection plates 2b3 of the double skin structure DS (pitch P in the Y direction).

  • the inner plate 2b2 has a plurality of holes 16 provided discretely at an equal pitch on the protrusion 18 along the extrusion direction (X direction) of the protrusion 18. Since the inner diameter d of the hole 16 is larger than the width dimension W of the protrusion 18 in the Y direction, a part of the hole 16 protrudes from the protrusion 18. It is preferable that the central axis of each hole 16 intersects the center line of the projection 18.

Since no adhesive or the like is applied to the gap 19 and a part of the hole 16 protruding from the protrusion 18 is not blocked, the compressional wave of the sound wave propagated into the space 15 can enter the vehicle interior side cavity 17 through the gap 19 and a part of the hole 16 along the sound wave entry path 21. Thus, the effect of improving the sound insulation performance can be obtained.
  • a force is applied in a direction in which the structure of the railway vehicle expands and contracts in a cross section due to an airtight load generated by internal and external pressure difference of the vehicle. Therefore, when an airtight load acts on the railway vehicle structure 1a (1b), as indicated by arrow 22, a tensile/compressive load acts in a direction intersecting the X direction on the double skin structure DS such as the roof structure 2a (2b) and the side structure 3 constituting the railway vehicle structure 1a (1b).
  • the provision of the protrusion 18 has an effect that the hole 16 can be easily positioned at the time of construction.
  • the protrusion 18 since it is difficult to understand the position of the connection plate 2b3 and the vehicle interior side cavity 17 only by viewing from the inner plate 2b2 side, it is difficult to machine the hole 16 without interfering with the connection plate 2b3 and the vehicle interior side cavity 17.
  • the provision of the protrusion 18 facilitates the positioning of the hole 16 by using the protrusion 18 as a marker, thereby improving the workability of drilling.
  • providing the protrusion 18 in the double skin structure makes it possible to provide a railway vehicle which can avoid a decrease in sound insulation performance due to the hole 16 being closed when the sound absorbing material 14 is bonded to the inner plate 2b2 and which can improve the fatigue durability and workability of the double skin structure.
