Description
Technical field
The utility model relates to a kind of vehicle body of railway vehicle, particularly aluminum alloy bodywork of rail vehicle side bar, belongs to guideway vehicle manufacturing technology field.
Background technology
The guideway vehicle speed per hour of current domestic place in operation has reached more than 300 kilometers, and when the speed per hour scope of vehicle more than 300 kilometers is run, the stressing conditions of side bar is comparatively complicated, and the performance figure such as structural strength for hanging equipment side bar require also more and more higher.
The side bar intensity of existing high speed railway car, requirement must meet European standard-EN12663:2010, also should have enough safety allowances simultaneously.Under hanging trolley, equipment side bar is as a main load bearing component of body construction, and its intensity, rigidity and strength at repeated alternation index seem and be even more important.
Under emphasizing that improper load working condition occurs, can not there is fracture accident in side bar, the fatigue load of namely require side bar to bear damage acceleration/accel load that EN12663-2010 standard specifies and nominal situation.
Guideway vehicle is run at high speed in process, and the change due to circuit needs different speed class to pass through, and therefore vehicle need be braked and accelerate continually, and the acceleration/accel load ratio causing side bar to bear is comparatively frequent, its dynamic stress also more complicated.
When under car, weight of equipment is larger, and in vehicle high-speed operational process, under car, the excitation frequency of equipment opposite side beam can be quite high, the force of inertia produced due to acceleration/accel is very large, side bar can produce very large dynamic stress and dynamic displacement, how reaching and to meet European standard-EN12663:2010, is the main difficult technical that existing hot-short car body design faces.
Summary of the invention
The utility model main purpose is to solve the problem, and provides one and can improve integral rigidity, intensity and fatigue resistance, meets the aluminum alloy bodywork of rail vehicle side bar that vehicle high-speed moves row performance requriements.
For achieving the above object, the technical solution of the utility model is:
A kind of aluminum alloy bodywork of rail vehicle side bar, comprise the side bar truss of hollow, bottom the interior plate of described side bar truss, be provided with the chute for equipment under hanging trolley, described side bar truss and described chute form integral structure by extrusion process.
Further, the section of described chute is the composite structure of triangle and the degree of lip-rounding, and notch is offered on the base of the degree of lip-rounding structure of described chute.
Further, the interior plate of described side bar truss is vertically arranged, and described chute and described interior plate be arranged in parallel.
Further, the inner chamber of described side bar truss is divided into multiple triangle by multiple gusset, and described chute is arranged on the side of the ditrigon inner chamber of bottom.
Further, the interior plate of described side bar truss has outwards been horizontally disposed with multiple connection supporting plate.
Further, the width of described chute is 30-50mm.
To sum up content, a kind of aluminum alloy bodywork of rail vehicle side bar described in the utility model, compared with prior art, tool has the following advantages:
(1) side bar truss of the present utility model and chute adopt one extrusion structure, integrated welding seam-free, significantly improve the fatigue resistance of side bar, and integral type side bar improves integral rigidity and mechanical strength, the operating needs bearing damage load that European standard requires can be reached, meanwhile, load can balancedly be distributed on side bar.
(2) sliding groove structure of side bar can hang equipment under various car easily, carries out counterweight, also improve the reliability of equipment hanging by vehicle equilibrium to equipment under car.
(3) the utility model adopts integral type side bar, and chute is adopted as the composite structure of triangular form and the shape of the mouth as one speaks, has increased substantially the vertical stiffness of side bar, improves the vertical natural bending frequency of side bar, avoids the oscillation frequency of equipment under car completely.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
As shown in Figure 1, side bar truss 1, interior plate 2, outer panel 3, chute 4, notch 5, connects supporting plate 6, gusset 7.
Detailed description of the invention
