According to the door corner structure for the vehicle door of a railway vehicle disclosed by the utility model, via the addition of the steel plate, the transverse deformations at the door corners are reduced, and the transverse stiffness and strength at the door corners are improved; and via the addition of the angle steel, the vertical stiffness and strength of the cross beam are improved, thus improving the bearing performance of the whole vehicle, and prolonging the life of the vehicle.
Description
Technical field
The utility model relates to a kind of corner structure, particularly a kind of rail vehicle every corner structure.
Background technology
As shown in Figure 1, the door angular zone of current track vehicle is comprised of side wall outer panel and door entablatrance, column and crossbeam are all thin-wall section structures, due to the door angle, there is weld seam in place, and the car body of guideway vehicle often exists serious stress to concentrate at this position, so cause this zone to produce endurance crack, make the weakness of whole car body due to this position, and the life-span is reduced.Domestic city rail vehicle is divided into two kinds of A type and Type Bs, and the parameter of two kinds of vehicles is compared as follows shown in table.
| ? | Length over ends of body (mm) | Width over sides of car body (mm) | Car door quantity | Vertical Maximum Loading Capacity (t) |
| The A type | 21880 | 3000 | 5 opposite houses | 53 |
| Type B | 19000 | 2800 | 4 opposite houses | 40 |
As can be seen from the table, the door quantity of A type city rail vehicle is many and load carrying ability is larger, can cause an angular zone stress concentration phenomenon even more serious.Calculate and the car body test of static strength by simulation analysis, find that this vehicle adopts previous structure can not meet the requirement of standard on intensity.Application disclosed patent and for example, application number 200720310832.9, name is called the doorframe structure of rolling stock car door, the doorframe structure that its scheme is a kind of rolling stock car door, by the column that is positioned at both sides, and the lower and upper cross-member composition, the place, four door angles be connected with crossbeam at described column is provided with " L " shape derby, described column and crossbeam all are fixed on described derby, and described derby is that stock or the sheet material of casting passes through cold-formed.This piece of patent is provided with " L " shape derby at Men Jiaochu, although this structure increases than the strength and stiffness of traditional thin-wall part, but because the door entablatrance is the shape for hat beam, the Side fascia carrying is only arranged in shape for hat beam hollow part, its rigidity obviously is weaker than a derby place, angle, therefore near the Side fascia place lateral deformation door angle is obvious and the stress concentration phenomenon is still comparatively serious, stress value often approaches the yield limit value of wall board material, and the strength margin at this place is on the low side.
The utility model content
The utility model main purpose is to address the above problem and is not enough, provides a kind of and can effectively reduce angular zone lateral deformation and a stress value, significantly improves rail vehicle every corner structure of the strength and stiffness of door angular zone.
For achieving the above object, the technical solution of the utility model is:
A kind of rail vehicle every corner structure, comprise two heel posts and door entablatrance, described column and described door entablatrance are fixedly connected to form an angle, described column and door entablatrance are fixedly connected on side wall, between described door entablatrance and described side wall, steel plate is set, the one side of described steel plate is welded and fixed with described door entablatrance and described column, another side and described sidewall welding are fixed, at described door angle, place arranges angle steel, and described angle steel is fixedly connected on the side of the bottom surface of described door entablatrance and described column.
Further, angle steel is fixedly connected with the base of described steel plate.
Further, the thickness of steel plate is 3-5mm.
Further, the thickness of angle steel is 3-5mm.
Further, steel plate and angle steel are stainless steel.
Content to sum up, a kind of rail vehicle every corner structure described in the utility model, by increasing steel plate, reduced the lateral deformation at place, door angle, improved door angle place's lateral stiffness and intensity.By increasing angle steel, increase vertical stiffness and the intensity of crossbeam, thereby improved the load-carrying properties of car load, increased the vehicle life-span.
The accompanying drawing explanation
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation.
As depicted in figs. 1 and 2, door entablatrance 1, column 2, steel plate 3, angle steel 4, hat brim 5, door angle derby 6.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in Figure 1, the doorframe top of rail vehicle door is comprised of door entablatrance 1 and two heel posts 2, door entablatrance 1 and column 2 are welded and fixed and form the door corner structure, door entablatrance 1 is the shape for hat beam, and crossbeam is hollow structure, and both sides are hat brim 5, door entablatrance 1 and column 2 are welded on the side wall at rear, door entablatrance 1 is welded on side wall by hat brim 5, has welded a door angle derby 6 at the place, door angle of door entablatrance 1 and column 2 formation, for increasing intensity.
As shown in Figure 2, rail vehicle every corner structure improves on the basis of said structure, the hat brim on one section both sides of door entablatrance 15 is removed, the local part of column 2 tops and sidewall welding is removed, make to leave gap between an entablatrance 1 and column 2 and side wall, enough insert steel plate 3, steel plate 3 is stainless steel, material is SUS 301L-MT, thickness is 3-5mm, take 4mm as optimal thickness, high strength, steel plate 3 one sides are connected with side wall spot welding, hollow cross limit and column 2 welded top of another side and door entablatrance 1.
By increasing steel plate 3, filled up the weak link of door entablatrance 1 hollow cross, make this position not only by framed side wallboard weak on side wall, carry out bearing pressure, increased rigidity, obviously reduced the lateral deformation at this position.After having improved the lateral stiffness of door angular zone framed side wallboard, the stress at this position is concentrated to manifest also and is obviously reduced, and the stress value of door angular zone obviously descends, and intensity is significantly improved.
Door angular zone in door entablatrance 1 and column 2 formation, be provided with angle steel 4, and angle steel 4 by original door angle derby 6 parcels wherein.Angle steel 4 is welded and fixed with bottom surface, the side of column 2 and the base of steel plate 3 of door entablatrance 1, and angle steel 4 is stainless steel, and material is SUS 301L-MT, and thickness is 3-5mm, take 4mm as optimal thickness.
After the door angular zone increases angle steel 4, increased the vertical stiffness of door entablatrance 1, the vertical relative deformation at the left and right door angle of whole car door is reduced, improved the vertical bending stiffness of car load simultaneously.
As mentioned above, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not break away from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
