Abstract
The utility model discloses a boundary simulation device for a test of a thin-wall cylindrical shell structure, which comprises a center support rod, an upper ring plate and a detachable lower ring plate. The upper ring plate and lower ring plate are used as templates for making a thin-wall cylindrical shell model, the boundary at the bottom of the thin-wall cylindrical shell model is coated with glass cement, bolts on the detachable lower ring plate are loosened to move the lower ring plate inwards, the inner side of the model is coated with a circle of the same glass cement to form a bottom fixed boundary condition; and at the top the thin-wall cylindrical shell, the top of the thin-wall cylindrical shell model is fixed on the upper ring plate by aluminum belts so as to form a top fixed boundary condition. The device can be flexibly detached and assembled and has two functions of acting as the templates during the process of manufacturing a test piece as well as forming bottom and top boundary conditions for the rest piece. When the top boundary is loosened, the device can simulate a shell body with a floating top; and when the top boundary is restricted, the device can simulate a shell body with a fixed top.
Description
Technical field
The utility model belongs to technical field of structural engineering, relates in particular to the boundary condition simulation device in a kind of Thin-Wall Cylindrical Shells structural test.
Background technology
Thin-Wall Cylindrical Shells is widely used in all kinds of shell structures in the civil engineering work, as storage tank, silo, tower mast, chimney and pipeline etc.The large cylindrical shell that is built on the soft soil foundation is easy to generate various distortion, and all non-uniform settlings of its mesochite are the most unfavorable to shell stability.Thin-Wall Cylindrical Shells is divided into floating top housing and solid top housing.The Thin-Wall Cylindrical Shells structural test is very responsive to boundary condition, therefore accurately simulation is extremely important for Thin-Wall Cylindrical Shells top and bottom boundary, this has proposed requirement to experimental provision, still, the report of the boundary condition simulation device that carries out the Thin-Wall Cylindrical Shells structural test is not arranged as yet at present.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and the boundary condition simulation device in a kind of Thin-Wall Cylindrical Shells structural test is provided.
The purpose of this utility model is achieved through the following technical solutions:
Boundary condition simulation device in a kind of Thin-Wall Cylindrical Shells structural test, it comprises: central support bar, upper ring plate, detachable Circular Plate and sleeve down.Upper ring plate is fixed on the central support bar by sleeve, and the end of central support bar and detachable following Circular Plate spin by screw thread, and upper ring plate is identical with detachable following Circular Plate radius.Wherein, described detachable down Circular Plate comprises four 1/4th outer toroid and an intermediate connector, intermediate connector by four connect steel plates respectively with four 1/4th detachable connections of outer toroid.
The beneficial effect that the utlity model has is: by this cover Thin-Wall Cylindrical Shells boundary condition analogue means, it can be made the thin wall cylindrical shell model as template, and form thin wall cylindrical shell model top and bottom fixed boundary well, can simulate solid top housing and floating top housing.The utility model is simple in structure, and cost is low, and can suppose that the Thin-Wall Cylindrical Shells of making does not have primary stress, has only how much very little initial imperfections, is applicable to the experimental study of Thin-Wall Cylindrical Shells.

Among the figure: 1, thin wall cylindrical shell model, 2, central support bar, 3, upper ring plate, 4, detachable Circular Plate down, 5, sleeve, 6, connect steel plate, 7, bolt, 8,1/4th outer toroid, 9, intermediate connector.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the boundary condition simulation device in the utility model Thin-Wall Cylindrical Shells structural test comprises: central support bar 2, upper ring plate 3, detachable Circular Plate 4 and sleeve 5 down.Wherein, upper ring plate 3 is fixed on the central support bar 2 by sleeve 5, and the end of central support bar 2 and detachable following Circular Plate 4 spin by screw thread, and upper ring plate 3 is identical with detachable following Circular Plate 4 radiuses.
Figure 2 shows that the structure of upper ring plate 3, it is mainly integrally formed by an outer toroid and a cross stiffening rib.There is a hole centre of cross stiffening rib, and central support bar 2 is fixed by sleeve 5 after passing this hole.
As shown in Figure 3, detachable down Circular Plate 4 comprises four 1/4th outer toroid 8 and an intermediate connector 9, intermediate connector 9 by four connect steel plates 6 respectively with 8 detachable connections of four 1/4th outer toroid.Connect between steel plate 6 and intermediate connector 9 and 1/4th outer toroid 8 and all be connected by bolt 7.There is a screwed hole of centre at intermediate connector 9 centers, and the end of central support bar 2 screws in this threaded hole.
The course of work of the present utility model is as follows:
1, by bolt 7 be connected steel plate 6 four 1/4th outer toroid 8 and an intermediate connector 9 linked together, form detachable Circular Plate 4 down, central support bar 2 is inserted the detachable screwed hole of centre of Circular Plate 4 down, again upper ring plate 3 is inserted in central support bar 2 backs and fixes with sleeve 5.
2, utilize upper ring plate 3 and detachable Circular Plate 4 down thin-walled material to be formed thin wall cylindrical shell model 1 as template.
Thin-walled material is a rectangle, is rolled into the thin wall cylindrical shell model 1 of round barrel shape around upper ring plate 3 and detachable down Circular Plate 4.Thin wall cylindrical shell model 1 can be formed by plastic productions such as mylars.
3, glass cement is applied to thin wall cylindrical shell model 1 excircle bottom, after glass cement solidified, the bolt 7 of outwarding winding will move in four 1/4th outer toroid 8, again at thin wall cylindrical shell model 1 inner periphery Tu upper glass glue, formed the bottom fixed boundary condition.
4, remove the floating top of upper ring plate 3 simulations housing; Or thin wall cylindrical shell model 1 top is fixed in outside the upper ring plate 3, form the top fixed boundary condition, thus the solid top of simulation housing.
