摘要： The present invention aims to provide a joint figuration inhibiting decrease in strength resulting from welding at the joint region, in a case where hollow-shaped material is friction stir welded. A face plate 101 (111) between a rib 105 (115) at the end portion of a hollow-shaped material 100 (110) and a rib 103 (113) has a thickness t2 (t5) at the rib 105 (115) side and ti at the rib 103 (113) side. The thickness t2 (t5) is thicker than ti. The thickness between the two is changed smoothly. The thickness of the plate thickness t2 (t5) is provided by projecting towards the other face plate side.

摘要： A car body, in which a hollow shape stock composed of two face plates and ribs joining the face plates together is used to form a side body, and stresses are reduced while minimizing an increase in mass. A car body, comprising a hollow shape stock composed of two face plates (31, 31) and ribs (32) joining the face plates together and used to form a side body (11), wherein face plate portions (31c, 31d) in regions (B, D) above and below connection points (c) between circular arcs, which constitute corner portions of a window (15), and vertical sides of the window (15) are greater in thickness than in the remaining regions (A, C, E). Stresses are most heavily concentrated in the regions (B, D). Therefore, it is possible to achieve reduction in mass and enhancement in strength together. Further, buckling preventive tools can be arranged in spaces in the regions (B, D) of the hollow shape stock. Further, with the hollow shape stock (18) in a pier panel, face plates on an internal side are greater in thickness than those on an external side.

摘要： In a railway car body formed of hollow shape members 40, a hollow shape member 51 having a shock absorbing function is provided to the ends of a hollow shape member 40 constituting an underframe 30, where impact load is most likely to be received. The hollow shape member 40 is positioned so that the longitudinal direction thereof is arranged along the longitudinal direction of the car body. When impact load is received, the hollow shape member 51 formed at the ends of the member 40 deforms and collapses, thereby relieving the impact force. The present invention simply provides treatment to some areas of the hollow shape members that form the car body without changing the conventional railway car structure greatly, thus minimizing the impact load provided to the passengers upon collision, and improves the safety of the railway car.

摘要： A front end portion 100 is disposed on the front end of a car body. The floor thereof consists of extruded hollow members 210 that constitute a shock absorber 200. The shock absorber 200 is divided into an upper shock absorber 200 and a lower shock absorber 200. Annealed extruded hollow members are used to form the hollow member 210. The hollow members 210 are disposed so that their direction of extrusion corresponds to the longitudinal direction of the car body. The hollow members 210 are divided longitudinally into two portions by a plate 220. At the width-direction ends of member 210, the face plates 211 and 212 are welded onto plates 223-226. Upon receiving impact load, members 210 fold up into concertinas, absorbing the impact force. Since members 210 are separated by a plate, they deform evenly and continuously into concertinas instead of being bent in half, capable of absorbing a large energy.

摘要： This invention relates to a method of fixing an inside panel of a car, and its fixing structure. In a structure for fixing an inside panel by employing an interior decoration material to form a passenger room of a car, the present invention relates to a method and a structure for fixing an inside panel of a car, particularly suitable for a railway car. An inside frame which is press-formed is fixed to frames of a car, and an inside panel is fixed to the inside frame through fasteners. Since the inside panel is fixed to the press-formed inside frame, surface uneveness does not occur on the inside panel even if any unevenness exists on the frames of the car. A cushion material is attached to the inside frame at the joint portion of two inside panels along the joint portion. The inside panel has a decoration sheet bonded to its surface, and this decoration sheet is bent back at the edge portions of the inside panel. Therefore, the appearance of the joint portion can be improved.
