摘要： PROBLEM TO BE SOLVED: To provide a body structure for a railroad head car capable of reducing impulsive noise caused by a micro-pressure wave further than a conventional head car regardless of whether a tunnel is just a regular one without buffer work or the tunnel is a buffered one.
SOLUTION: The cross sectional area of the car body is changed along the longitudinal direction so that the pressure gradient of a compression wave generated when the car enters in a tunnel without buffer work reaches the maximum value at the head part, and gradually decreases toward a general part through an intermediate part. The cross sectional area increasing rate of the head part Z1 decreases gradually in a front side sectional area increasing region Z11 in a range approximately from 5.0 m
2 /m to 2.5 m
2 /m, and the area ratio relative to the cross sectional area of the general part Z2 is within 0-0.30, respectively. The cross sectional area increases gradually from the intermediate cross sectional area increasing region Z12 and the rear side sectional area increasing region Z13 of the head part to the general part Z2 with a cross sectional increasing rate smaller than that in the front side sectional area increasing region Z11.

摘要： PROBLEM TO BE SOLVED: To provide a railroad vehicle body structure having a stainless steel semi-monocoque structure which is capable of increasing the strength against an impact from the transverse direction without narrowing a cabin space by a reinforcing structure.
SOLUTION: In a stainless steel semi-monocoque vehicle body structure in which side beams and transverse beams of an underframe are members of a U-shaped section (members of hat-shaped section), The position of the transverse beams of the underframe is agreed with the position of lower ends of a side column 12 of a side structure and an entrance column 13, and these members are connected to each other. The position of a rafter 3 of a roof structure is agreed with the position of upper ends of the side column 12 and the entrance column 13, and these members are connected to each other. A lip is welded to edges of upper and lower flanges of the transverse beams to reinforce the transverse beams. A reinforcing member is fitted and welded to the side beams at the lower end position of the side column, the lower end of the side column is welded to a top side of the side beams, and the lower end of the side column and the end of the transverse beam are integrally fixed to each other via the reinforcing member.

摘要： PROBLEM TO BE SOLVED: To provide a car of rapid-transit railway vehicle capable of changing the length of a forefront portion.
SOLUTION: The forefront portion 2 is composed of a rear side portion 7 including a driving room 4, and a front side portion 8 positioned in front of the rear side portion 7. The front side portion is made to be a movable portion. The front side portion 8 is moved in a vehicular body back-and-forth direction to be in a rapid traveling state wherein the front side portion 8 is positioned in front of the rear side portion to make length in the vehicular body back-and-forth direction long or in a slow traveling state wherein the front side portion 8 is positioned at a more rear side than that in the rapid traveling state to make the length in the vehicular body back-and-forth direction short.

摘要： PROBLEM TO BE SOLVED: To provide an energy absorbing structure in a rolling stock and the like which can be expected to have a high absorbing energy by getting a stable buckling load. SOLUTION: Linear form slits 5c and 5d are formed by inclining to the axial line along the neighboring surface plates 4A to 4D, by slipping the cycle to the corner parts at the positions separating at a specific distance from one side end of a hollow square tube member 1. In order to advance the plastic buckling deformation while maintaining the continuety of the buckling deformation, the slits 5c and 5d are provided symmetrically. The slits 5c and 5d have the inclination 45 deg. to the axial direction, and they are extended almost the same length at the neighboring surface plates 4C and 4D.
