Air is circulated throughout the longitudinal direction of the vehicle through the duct 20.
  • the underframe 4 since the position of the floor plate 63 in the height direction is determined so as not to cause a step with the platform of the station, the underframe 4 includes the air supply duct 13, the return air duct 14, and the exhaust duct. It needs to be placed below so as not to interfere with 20. On top of that, since the underfloor equipment is mounted below the underframe 4, the underframe 4 needs to have a structure that does not interfere with the underfloor equipment.
  • the railway vehicle structure 1 of the high-speed vehicle 1 Has an airtight structure. Since a pressure difference is generated inside and outside the vehicle due to such an airtight structure, the railway vehicle structure 1 expands and contracts in the cross-sectional direction. This pressure difference is called airtight pressure.
  • the underframe 4 is flat because the floor plate 63 and the underfloor equipment are horizontally attached.
  • a flat plate is structurally weaker than a curved plate with respect to a pressure acting in the out-of-plane direction, and is liable to cause excessive deformation or stress. Therefore, in order to reduce these deformations and stresses, the underframe 4 needs to have a structure having a sufficient moment of inertia of area and a cross-sectional coefficient.
  • the underframe 4 of the high-speed vehicle uses a thin T-ribbed profile 61 for air conditioning such as an air supply duct 13, a return air duct 14, and an exhaust duct 20. It is intended to avoid interference with ducts and underfloor equipment. Further, by arranging the cross beam 62 having a height in the vertical direction of the vehicle at a position where it does not interfere with the underfloor equipment, it is intended to secure a sufficient moment of inertia of area and a section coefficient with respect to the airtight pressure.
  • the underframe is formed of a hollow profile in which the thickness of the central portion in the width direction is thicker than the thickness of the end portion in the width direction as shown in FIG. 2 of Patent Document 3, and the width of the underframe is formed.
  • a rail vehicle structure that secures rigidity and strength against airtight pressure that generates a large bending load in the central part of the direction has been proposed.
  • a thick hollow profile has a high degree of difficulty in manufacturing, and tends to be thicker and smaller than a general-thick hollow profile. This leads to an increase in the mass of the rail vehicle structure and an increase in the manufacturing cost due to an increase in the amount of welding. Further, the internal use of the hollow profile as a space for returning air leads to an increase in manufacturing cost due to an increase in the processing amount of the hollow profile.
  • the rail vehicle structure In order to reduce the manufacturing cost of the rail vehicle, it is desirable to configure the rail vehicle structure with a hollow profile to simplify the production.
  • air-conditioning ducts and underfloor equipment are densely packed above and below, so the hollow profile that avoids interference with them ensures rigidity and strength against airtight pressure, while increasing mass. It is difficult to suppress the increase in manufacturing cost.
