摘要:
A method is provided for making a passenger car body structure which has a panel assembly forming at least part of a side, the roof, and end of the floorplate. Each panel has inner and outer spaced metal sheets and a cellular metal core brazed to the sheets and maintaining them spaced apart. To join the panels, a metal connecting member is joined to at least one of the inner and outer sheets and has a projection for use in welding the panel to the neighboring panel. The projection extends in the lateral direction of the panel and is preferably of material thicker than the general sheet thickness of the sheets. A frame member of the body structure may be welded to the panels at the joint.

A railway car body structure has a panel assembly forming at least part of a side, the roof, an end or the floorplate. Each panel has inner and outer spaced metal sheets and a cellular metal core bonded to the sheets and maintaining them spaced apart. To join the panels, a metal connecting member is joined to at least one of the inner and outer sheets by continuous metal-to-metal bonding and has a projection for use in welding the panel to the neighboring panel. The projection extends in the lateral direction of the panel and is of material thicker than the general sheet thickness of the sheets. A frame member of the body structure may be welded to the panels at the joint.
摘要:
A car body for high speed railway rolling stock and a method of fabricating the same wherein, in order to prevent a variation of external pressures produced when the rolling stock travels at high speeds from being propagated into the interior of the car body, the car body is of an air-type construction. The car body has a reduced weight and is capable of withstanding a variation of the external pressures by the provision of a construction in which the underframe of the car body includes a curved surface having at least one radius of curvature extending across a width of the car body.
摘要:
A railway car body structure running at a high speed and a production method thereof. To reduce vibration and noise and to prevent influences of outdoor pressure variations on passengers in the case of a high-speed railway car, the weight of the car body structure must be reduced and its pressure resistance must be improved. Each of the side units, roof unit and end unit and floor plates of an underframe of the car body structure includes plate members obtained by joining two surface materials, a core material and binding materials through metal-to-metal bonding. The sheet thickness of the surface material on an outdoor side is greater than a sheet thickness of the surface material on an indoor side. The plate members are constructed as a block, and a plurality of blocks are joined so as to form the side units, roof unit or the floor plates of the underframe.

A method of manufacturing a portion of a vehicle body, with the portion being at least part of one of a side, an end, a roof, and a floor plate of the body. The method comprises the steps of providing extruded metal plates formed of a light alloy metal with each of the plates having welding edges and integral structural ribs extending parallel to the welding edges on the inner face of the plates, arranging the plates on a jig in position for welding of the welding edges, without an overlap of the welding edges, restraining the plates in a welding position on the jig, and welding the welding edges on the jig by one-sided welding from an inner side of the plates to produce continuous welds. Frame members extending transversely to the structural ribs can be welded on the same side without moving the plate from the jig.

A vehicle body, such as, for example, a railway passenger vehicle body, which includes an external body sheeting formed of opposite sides and a roof and having an internal floor extending between the sides. The sides, above the level of the internal floor, and the roof each include a number of extruded metal plates forming the external body sheeting and integral ribs, extending in a longitudinal direction of the vehicle body, are provided on inner faces of the extruded metal plates. The extruded metal plates are welded together at weld lines extending in a longitudinal direction of the vehicle body.

A honeycomb panel having a honeycomb core interposed between two face plates, and inserts which are exposed to an opening formed through the panel. A desired member is bonded to the panel through the inserts and the face plates which are bonded together. The inserts are disposed in selected honeycomb cells of the honeycomb core when the honeycomb core is assembled with the face plates, or the inserts are inserted into the selected honeycomb cells which are open to the opening or a preliminary hole formed before the opening is cut. Alternatively, the inserts are positioned relative to the face plates before the honeycomb core members are disposed relative to the inserts. The honeycomb panel may be produced by various methods disclosed.

A rolling stock ventilator including an air supply fan, an exhaust fan an inverter for changing air feed characteristics of the air supply fan and the exhaust fan. Flow path resistance changers, a tunnel detector to detect the presence of a tunnel, and a car internal pressure detector are also provided. A controller provides signals to the inverters and the flow path resistance changers with the signals representing a control command to change the operation frequency of the air supply fan and the exhaust fan in accordance with the result of a detection by the tunnel detector and the car internal pressure detector and also provides a control command to change the air feed resistance of the flow path resistance changers.

A railway car body structure is provided which includes an underframe, first and second side structural units and a roof structural unit. Each of the first and second side structural units and the roof structural unit include at least one plate member, each plate members being formed by joining two surface materials, a core material and binding materials through metal-to-metal brazing. The first side structural units is joined to the roof structural unit by a first extruded element, while the second side structural unit is joined to the roof structural unit by a second extruded element. With this construction an extremely strong, yet light, railway car body structure is achieved.
