The difference with the prior art part is that described connection structure is closed, the assembly welding framework that is welded through each parts;
Described end wall panel has through assembly welding and is connected to integrally-built hollow material and skeleton, has enough airtight strength and stiffness to guarantee it.
End wall panel carries out welding assembly through slab and girder and connection structure.
Like above-mentioned basic scheme characteristic; The headwall integral structure adopts big section aluminium alloy hollow section bar; Headwall and side wall, roof and underframe section bar connection structure are high strength, high rigidity type of attachment; Can the clamp load that headwall bears successfully be passed to side wall, roof and underframe, guarantee the harmony of whole car body resistance to deformation and antitorque commentaries on classics performance, help improving the safety and the fatigue reliability of headwall structure.
For the ability to bear that improves car body end accident load further and the intensity between the connecting portion, can take following improvement project,
Described connection structure adopts big section type equipment structure, and have with first attaching parts of side wall, with second attaching parts of roof, with the 3rd attaching parts of underframe.
Connection structure adopts big section type equipment structure, and its effect is to make headwall can bear bigger end accident load.Simultaneously, adopt the link of this class formation also can increase Joint strenght, reduce pressure and concentrate.
To the actual demand of passenger's walking between the car body, replenishing the refinement measure is the doorframe structure that end wall panel is provided with the headwall valve.
Prioritization scheme to the side wall link is, described first attaching parts adopts the rectangular aluminium alloy hollow material, and set inside has several A portion gussets.
Be to increase the rigidity and the connective stability of link, the end corner post of said first attaching parts has big section structure, is provided with boss with the coupling end of end wall panel, is provided with the side wall connecting panel with the coupling end of side wall section bar.
Prioritization scheme to the roof link is, described second attaching parts is a hollow material rectangular beam structure, and set inside has oblique, continuous B portion gusset, is provided with the roof connecting panel with the coupling end of roof section bar.
Prioritization scheme to the underframe link is, described the 3rd attaching parts adopts the aluminium alloy hollow section bar, and set inside has oblique, continuous C portion gusset.
For increasing the rigidity and the connective stability of link, the 3rd attaching parts includes the column of big section rectangular beam structure, and the coupling end of column and end wall panel is provided with the side direction boss, and its opposite side is provided with dihedral overlap joint mouth.
Content to sum up, advantage and beneficial effect that high-speed track vehicle car body headwall of the present invention has are:
1, realizes being connected of high strength, high rigidity between headwall and side wall, roof and the underframe; Can bear ± aerodynamic loading of 6000Pa; Reach the clamp load of EN12663 standard code, thus car body resistance to deformation and torsion proof rigidity criteria when improving passive security protection, high speed meeting.
2, the hollow material rigidity of structure of headwall is higher, the airtight strength at repeated alternation of structure is higher.
3, the welded air-tightness of section bar is better, more easily guarantees the air-tightness of band valve structure.
4, reduced the work capacity of manual welding in large quantities, can improve the automated welding level to guarantee welding quality.
