Description
Technical field
The present invention relates to a kind of rail road tank car traction and bolster.
Background technology
At present; All adopted cover plate structure under the sleeper beam in existing tens thousand of the rail road tank car traction and bolster structures of China, as depicted in figs. 1 and 2, it is between the draw beam and body center plate that are formed by two Yi shape steel assembly weldings; It structurally deposits a bending region, tie welding with sleeper beam under the side cover plate bottom surface.
Because the excitation of track irregularity, tank car is bearing complicated dynamic load effect, and tank car pillow pulling structure is born complicated dynamic stress.Cover plate structure under the sleeper beam is because between the draw beam and body center plate that are formed by two Yi shape steel assembly weldings; With the tank car car body operating mode of drifting along is example; The vertical vibration of bogie truck passes to body center plate through truck center plate, passes to side cover plate under draw beam, integral type rear draft lug and center filler, the sleeper beam through cover plate under the sleeper beam again, and cover plate is on the direct bang path of live load under the sleeper beam; Self bear the dynamic stress of alternation, force-bearing situation is comparatively abominable.
Cover plate is owing to structurally exist the bending region under the sleeper beam, in the manufacturing process of reality, to the pillow pulling group to self the stressed adverse influence of all having brought.For a long time, this influence is not realized, and structurally continues to use original design always.
A kind of influence be the existence of bending region influence cover plate and draw beam under the sleeper beam group to after symmetry, mainly be because bending is not the processing technology of a precise forming, the bigger symmetry error of the bending of cover plate both sides existence under the same sleeper beam; Be used for simultaneously with sleeper beam under the right draw beam of cover plate group form by two Yi shape steel assembly weldings, the width error that the Yi shape steel lower aerofoil exists also can influence group to after symmetry.These two principal elements can cause under the sleeper beam cover plate group to back on the Yi shape steel lower aerofoil with respect to draw beam and asymmetric (the nearly 20mm that the symmetry tolerance is big); Make to produce local gap between the cover plate under Yi shape steel lower aerofoil and the sleeper beam of draw beam one side, as shown in Figure 3.
Careful research of structure stress FEM calculation and Test Study on Strength result show; The existence of this local gap is remarkable for the stressing influence of cover plate structure under the sleeper beam: influence cover plate structure under the sleeper beam and the live load of body center plate transmission is delivered to side cover plate gets under the sleeper beam that the big Yi shape steel lower aerofoil of rigidity and sleeper beam form; The cover plate structure self is born the live load that can't transmit owing to the existence in gap, the dynamic stress of bearing alternation in the bending region under the sleeper beam.Result of study shows that when the side cover plate contact condition was good under cover plate under the sleeper beam and the sleeper beam, the stress level of cover plate structure appeared near the bending region under the sleeper beam about 60Mpa; And local gap is when big, and the stress level of cover plate structure appears near the bending region about 167Mpa under the sleeper beam, apparently higher than the former.
Second kind of adverse effect is: the bending region of cover plate is through realizing through Bending Processing technology on the numerical control bending lathe under the sleeper beam; Bending Processing technology is a kind of plastic forming technology, can cause having unrelieved stress in the bending region, owing to be upwards bending; For cover plate under the sleeper beam; Can bear the residual tension effect at lower surface, the unrelieved stress test result of carrying out shows that the numerical value of residual tension approaches 100Mpa; For cover plate under the sleeper beam that bears reverse stress; The bending region exists bigger unrelieved stress to be equivalent to increase the steady component of stress numerical value that it bore, and has reduced structure bearing capacity, and is unfavorable to the strength at repeated alternation of structure.
The third adverse effect is: all factors such as resilience of sheet material after manufacturing errors and the bending during owing to Bending Processing; The accuracy of cover plate radius bend is difficult to accurate assurance under the sleeper beam; Cause under the sleeper beam that can there be bigger gap in side cover plate under the cover plate and sleeper beam when assembly welding, when assembly welding,, have to use frock to make under the sleeper beam cover plate K/UP again for reducing the gap; As shown in Figure 4, further aggravated near the stressed bending region of cover plate under the sleeper beam.
Simultaneously, the cover plate thickness of slab is 10mm under the existing tank car sleeper beam, and material is 0345A, and the margin of strength of self is not enough.
More than various adverse influences increased the risk of tank car pillow pulling structural failure, cause the part tank car in utilization, near cover plate structure bending region under the sleeper beam, to occur connecting endurance crack longitudinally along car body.
Summary of the invention
In order to solve the problem that endurance crack appears in cover plate structure under the tank car sleeper beam that exists in the prior art, the invention provides a kind of tank car pillow pulling.
The technical scheme of technical solution problem of the present invention is: a kind of tank car pillow pulling comprises draw beam and is arranged under the sleeper beam of draw beam below cover plate under the side cover plate and sleeper beam; Side cover plate is arranged at the both sides of cover plate under the sleeper beam under the said sleeper beam; Its special character is: cover plate is set to slab construction under the said sleeper beam.
Side cover plate is provided with the waling plate in the bending region near draw beam under the above-mentioned sleeper beam.
The thickness of cover plate is 10～16mm under the above-mentioned sleeper beam.
The material of cover plate is Q450NQR1 under the above-mentioned sleeper beam.
The structure of cover plate is suitable under above-mentioned body bolster diaphragm and the sleeper beam.
Tank car pillow pulling of the present invention has the following advantages:
1, eliminates the local gap between the cover plate under Yi shape steel lower aerofoil and the sleeper beam of draw beam one side, improved the strength at repeated alternation reliability of structure.
2, eliminate the bending unrelieved stress that original design exists, improved the strength at repeated alternation reliability of structure.
3, solved the powerful packing problem that original structure exists during the side cover plate assembly welding under cover plate and the sleeper beam under the welding sleeper beam.
4, improved the margin of strength of cover plate under the sleeper beam.
5, simple in structure, can adapt to existing tank car production facilities and technology.
