Abstract
The utility model discloses a locomotive side wall supporting structure, which comprises a top part supporting side beam and a bottom part supporting side beam, wherein, a vertical supporting beam and a supporting structure are arranged between the top part supporting side beam and the bottom part supporting side beam, and is characterized in that the supporting structure is of a cross inclined supporting structure which consists of two beams. The locomotive side wall supporting structure has the advantages that the stress distribution of the locomotive structure can be more reasonable, and the stress concentration can be reduced and the integral rigidness and stability of the locomotive body can be improved; with the side wall cross inclined supporting structure, the weight reduction of the locomotive body can be better optimized. The strength, the ratio of deflection to span and the one-stage vertical bending modal frequency of the locomotive optimized structure can satisfy relevant standard requirements.
Description
Technical field
The utility model relates to the car body of diesel locomotive, particularly a kind of supporting construction of locomotive side wall.
Background technology
Current general-duty diesel locomotive car body (as east wind 8B locomotive car body, east wind 4B locomotive car body) is compared, and former locomotive sidewall structure is illustrated in figure 1 as side wall monocline support structure mostly, and this structure forms stress concentration easily in the diagonal brace end.
As the main carrying structure of locomotive, steel structure of car body must be realized light-weight design satisfying under car body strength, the rigidity requirement, to satisfy important the asking of axle of locomotive.And the structure of side wall will directly have influence on the rigidity of car body, and whether intensity meets design requirement.Occur stress concentration in structure shown in Figure 1 easily, stress exceeds standard, and causes the work of steel structure of car body loss of weight to carry out.
Summary of the invention
The purpose of this utility model is: provide a kind of body construction distribution of stress that makes more reasonable, reduced stress concentration, also improved the locomotive side wall supporting construction of car body integral rigidity and stability.
The technical solution of the utility model is:
A kind of locomotive side wall supporting construction, comprise top braces curb girder and bottom support curb girder, be fixed with vertical support beam and supporting construction between top braces curb girder and bottom support curb girder, it is characterized in that: described supporting construction is the cross diagonal brace structure that 2 beams are formed.
The beneficial effects of the utility model are: by careful demonstration, computational analysis, this cross diagonal brace structure, make the body construction distribution of stress more reasonable, reduced stress concentration, also improved car body integral rigidity and stability, also made car body optimize the more optimization that loss of weight carries out by this side wall cross diagonal brace structure.The intensity that car body is optimized structure, deflection span ratio, single order hang down and bend the satisfied relevant base of calculation requirement of model frequency.Through experiment test, use the locomotive of this locomotive side wall supporting construction to use well now, also verified the success of this structure design.
Description of drawings
Fig. 1 is the scheme drawing of the supporting construction of locomotive side wall in the prior art.
Fig. 2 is the scheme drawing of locomotive side wall supporting construction of the present utility model.
Wherein, Reference numeral: 1 is the top braces curb girder, and 2 is vertical support beam, and 3 is the bottom support curb girder, and 4 is the monocline support structure, and 5 is cross diagonal brace structure.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Specific embodiment of the utility model, a kind of locomotive side wall supporting construction, as shown in Figure 1, include and similar top braces curb girder 1 of existing locomotive side wall construction and bottom support curb girder 3, and fixing vertical support beam 2 between top braces curb girder 1 and the bottom support curb girder 3, difference is to have replaced in the existing locomotive monocline support structure 4 between the top braces curb girder 1 and bottom support curb girder 3 as supporting construction with cross diagonal brace structure 5.
Claims (1)
1. locomotive side wall supporting construction, comprise top braces curb girder and bottom support curb girder, be fixed with vertical support beam and supporting construction between top braces curb girder and bottom support curb girder, it is characterized in that: described supporting construction is the cross diagonal brace structure that 2 beams are formed.
