In prior art (see Fig. 1), low temperature liquid transport vehicle tank body shell comprises dished end 1, cylindrical shell 2 and little reinforcing pad 3; Described little reinforcing pad 3 is U-shaped reinforcing pad; Described dished end 1 is arranged on cylindrical shell 2 two ends; The external diameter 2490mm of described cylindrical shell 2, length 11795mm, it is outside that described little reinforcing pad 3 is arranged on cylindrical shell 2 along cylindrical shell 2 axis direction, and the height of little reinforcing pad 3 is 50mm, and width is 80mm, and thickness is 4mm; Described dished end 1, cylindrical shell 2 and little reinforcing pad 3 material are Q345R.Be optimized design to model in Fig. 1, utilize ANSYS to carry out Eigenvalue Buckling Analysis, displacement boundary conditions is: the two ends dished end 1 curved surface degree of depth 1/3 position applies hoop displacement constraint, and wherein one end applies longitudinal travel constraint simultaneously; Force boundary condition is: cylindrical shell 2 outside face bears the well-distributed pressure of 0.1MPa, and can show that buckling load coefficient is 2.6253, namely critical pressure is 0.26253MPa.Buckling load coefficient is 2.6253 specified values being greater than (ASMEB & PCodeVIII-2) in relevant criterion, and structure can meet stability requirement.
Utility model content
For the deficiencies in the prior art, the technical matters that the utility model quasi-solution is determined is, a kind of low temperature liquid transport vehicle tank body shell is provided, stability analysis is carried out by strengthening structure to large reinforcing pad and little reinforcing pad combination level, adopt finite element optimization method, minimum for optimization aim with quality, to meet stability requirement for constraint condition, obtain the optimal location of large reinforcing pad and the optimal size of large reinforcing pad and little reinforcing pad, reduce the usage quantity of all reinforcing pads, save material, reduce costs, actv. reduces quality, thus the lightweight of implementation structure.
The technical scheme that the utility model solve the technical problem is, provides a kind of low temperature liquid transport vehicle tank body shell, comprises dished end, cylindrical shell and outer shell reinforcing structure; Described dished end is arranged on cylindrical shell two ends; Described outer shell reinforcing structure is arranged on cylindrical shell outside along tubular axis direction; It is characterized in that described outer shell reinforcing structure comprises large reinforcing pad and little reinforcing pad; Described large reinforcing pad is two, and two large reinforcing pads are equal with the distance of cylindrical shell middle, and the spacing of two large reinforcing pads is 1/4 of cylindrical shell overall length.
Compared with prior art, the utility model beneficial effect is: adopt large reinforcing pad and little reinforcing pad combination level to strengthen structure, actv. improves the anti-unstability ability of cylindrical shell; Stability analysis is carried out by strengthening structure to large reinforcing pad and little reinforcing pad combination level, adopt finite element optimization method, minimum for optimization aim with quality, to meet stability requirement for constraint condition, obtain the optimal location of large reinforcing pad and the optimal size of large reinforcing pad and little reinforcing pad, reduce the usage quantity of all reinforcing pads, save material, reduce costs, actv. reduces quality, thus the lightweight of implementation structure.

Detailed description of the invention
The utility model provides and is described further the utility model below in conjunction with accompanying drawing.
Embodiment
The utility model discloses a kind of low temperature liquid transport vehicle tank body shell (see Fig. 2), comprise dished end 1, cylindrical shell 2, little reinforcing pad 3 and large reinforcing pad 4; Described large reinforcing pad 4 is semi-circular reinforcing pad, and little reinforcing pad 3 is U-shaped reinforcing pad; Large reinforcing pad has stronger anti-unstability ability, and during usual structural instability, these tension members can not unstability, plays a supportive role; The anti-unstability energy force rate of little reinforcing pad is enclosed by force weak, for increasing cylindrical portions rigidity greatly;
Described dished end 1 is arranged on cylindrical shell 2 two ends; The external diameter 2490mm of described cylindrical shell 2, length 11795mm, described little reinforcing pad 3 and large reinforcing pad 4 are arranged on cylindrical shell outside along tubular axis direction; The height of described little reinforcing pad 3 is 50mm, and width is 80mm, and thickness is 4mm; Described large reinforcing pad 4 is two, and thickness is 4mm, has 10mm straight section; Described dished end 1, cylindrical shell 2, little reinforcing pad 3 and large reinforcing pad 4 material are Q345R.
Be optimized design to model in Fig. 2, utilize ANSYS to carry out Eigenvalue Buckling Analysis, displacement boundary conditions is: the two ends dished end 1 curved surface degree of depth 1/3 position applies hoop displacement constraint, and wherein one end applies longitudinal travel constraint simultaneously; Force boundary condition is: cylindrical shell 2 outside face bears the well-distributed pressure of 0.1MPa, obtains the optimal size R=79mm of large reinforcing pad; Two large reinforcing pads are equal with the distance of cylindrical shell middle, and the spacing of two large reinforcing pads is 1/4 of cylindrical shell overall length.Can show that buckling load coefficient is 2.63287, namely critical pressure is 0.263287MPa simultaneously.Buckling load coefficient is 2.6 specified values being greater than (ASMEB & PCodeVIII-2) in relevant criterion, and structure can meet stability requirement.Now compared with low temperature liquid transport vehicle tank body shell existing shown in Fig. 1, the quantity of all reinforcing pads is kept to 21 by 26, and quality is kept to 918.74kg by 1078.12kg.Visible, under ensureing that structure has the prerequisite of suitable critical pressure, reinforcing pad quality can be alleviated, and reduce the quantity of reinforcing pad, can implementation structure lightweight and reduce reinforcing pad welding manufacture and inspection cost.
