る。In the prior art described above, with the recent improvement in the extrusion molding technique for light alloy materials, the outer plate member is kept at a distance between a pair of substantially parallel plate portions and the plate portions. For example, it is composed of partition walls connected so as to form a triangle. In this way, by eliminating or reducing the bone members installed along the vehicle body circumferential direction,
We are taking measures to reduce costs by reducing the number of parts. However, when the outer plate member is a hollow extruded member composed of a pair of plate portions and a partition, there is a limit in reducing the thickness of the plate portion and the partition, and a limit in reducing the weight of the vehicle body. In recent years, railway vehicles have tended to operate at higher speeds, and it is important not only to reduce the weight of the vehicle but also to ensure strength against airtight pressure loads. In such a situation, it is very important to reduce the weight and strength of the portion where the hollow extruded material is used.

とができる。According to such a configuration, when the pressure load P is applied to the vehicle body 1 as shown in FIG. 2, the vehicle body 1 is deformed as shown by a deformation line F. At this time, an inflection point of the deformation of the roof structure 2 and the side structure 3 occurs near the point S of the eave member 32. FIG. 5 shows details of the eave member 32. 5, the inner plate portion 32b which forms the outer plate portion 32a and the vehicle body plane <br/> forming a body outer surface of the該軒member 32, the cross-sectional shape axisymmetric i.e. equivalent with respect to the plate section neutral axis T Sheet thickness . Therefore, even if the bending moment M is applied to the eave member 32,
The outer plate portion 32a bears the in-plane force F1 and the inner plate portion 32b bears the in-plane force F2.
Out of plane deformation hardly occurs in 2b, and deformation of the eave member 32 is suppressed. In general, when a pressure load P is applied to the vehicle body 1, deformation of the eave member 32 greatly affects the overall strength of the vehicle body 1. According to the configuration shown in the present embodiment, when the pressure load P is applied to the vehicle body 1, the deformation of the eave member 32 at the inflection point S is suppressed, and the deformation of each part of the vehicle body 1 is reduced. As a result, it is also possible to reduce the stress generated in each member constituting the vehicle body 1.

Also, the outer plate portion 101 and the inner plate portion 102 have a vertex C
Since the n and the apex Dn are connected at the shortest distance, the weight can be reduced as compared with a conventional vehicle body made of a hollow extruded material in which the outer plate portion and the inner plate portion are formed into curved surfaces. Further, in this embodiment, an example in which the external pressure is lower than the internal pressure has been described. However, contrary to the above description, even when the external pressure is higher than the internal pressure, the stress generated in the plate portion may be reduced. Just reverse the sign of

できる。At this time, an inflection point of the deformation of the roof structure 2 and the side structure 3 occurs near the point S of the eave member 320. FIG. 8 shows details of the eave member 320. In FIG. 8, the eave member 32
The neutral axes of the 0 outer plate portion 320a and the inner plate portion 320b are not linear . Therefore, the eave member 32
0, a bending moment M due to the pressure load P is added, and the outer plate 320a has an in-plane force F1 and the inner plate 320b.
When the in-plane force F2 acting on the outer plate 320a and the inner plate 320b, the out-of-plane deformation of the outer plate 320a and the inner plate 320b increases. Therefore, the deformation of the eave member 320 at the inflection point S increases, and the deformation of each part of the vehicle body 1 increases. As a result, the generated stress of each member constituting the vehicle body 1 also increases. Further, since the amount of deformation of each part of the vehicle body increases, creaking of the interior material attached to the vehicle body occurs, which contributes to an increase in vehicle interior noise.
As described above, the embodiment of the present invention can solve these conventional problems without increasing the plate thickness of the constituent members.
