Abstract

The application provides a loading device and a loading method for transverse compression of an array pipe combination structure. The device comprises a lower die and an upper driving assembly. The lower die is in the shape of a rectangular groove, and both sides of the lower die are provided with baffles. The baffles are provided with vertical grooves for installing transverse baffles that can be adjusted up and down. The upper driving assembly is connected to a pressure head, so that the pressure head extends into the rectangular groove through the opening of the transverse baffle and locally compresses the array pipe combination structure placed in the groove. The cross-sectional size of the opening is smaller than that of the rectangular groove, and the size of the pressure head is matched with that of the opening of the lower die. The cross-sectional size of the rectangular groove is larger than that of the opening, so that the pipe body directly below the projection of the pressure head is surrounded by the pipe body that is not compressed, that is, the pipe body is in a semi-rigid constraint, thereby achieving the purpose of simulating the boundary condition of the local compression deformation of the array pipe, and providing a reference for exploring the deformation and energy consumption characteristics of the combined pipe structure in engineering applications.

Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of material mechanics, and particularly relates to a loading device and a loading method for transverse compression of an arrayed circular pipe combined structure. BACKGROUND

[0002] In the fields of bumpers of vehicle engineering, crash barriers of bridge piers, and cushion supports of tunnel engineering, thin-walled (filling) structures such as square tubes, circular tubes, and filling tubes are relatively common cushioning and energy-absorbing elements. When the thin-walled tubes are placed in multiple layers, the deformation and energy-absorbing characteristics of the combined structure in transverse compression are obviously different from those of a single tube in transverse compression due to the interaction between the tubes. In some application scenarios, the combined tube is subjected to local compression rather than uniform overall compression. The constraint condition on the outside of the directly compressed combined tube is neither an absolute rigid displacement constraint nor a free unconstraint, but a "semi-rigid" constraint therebetween. In addition, in the combined structure of circular tubes, the tubes are not directly fixed and connected, and it is difficult to carry out a compression mechanics test of the combined tube under multiple-layer placement without a limiting device. If the limiting device is too close to the pressure head of the loading equipment, it constitutes an absolute rigid displacement constraint, which does not conform to the engineering application scenario of local compression of the combined tube.

[0033] The bottom mold 2 has a rectangular groove with an opening at the top. The cross-sectional area inside the rectangular groove is larger than the cross-sectional area of ​​the opening. The rectangular groove contains multiple circular tubes 6 with their outer walls in contact with each other. The top mold 1 is located directly above the bottom mold 2 and has a pressure head whose size is matched to the size of the opening. The driving end of the driving component 3 is connected to the end of the top mold 1 away from the bottom mold 2. When the driving component 3 is driven, the driving end causes the top mold 1 to move towards the bottom mold 2, so that the pressure head extends into the rectangular groove from the inlet to squeeze the circular tubes 6.

[0034] Specifically, the embodiment one of the present application proposes a loading device for lateral compression of arrayed circular tube combination structure, by filling several circular tubes 6 in the rectangular groove of the bottom die 2, and then locally compressing the several circular tubes 6 by the ram of the top die 1 which extends into the rectangular groove through the opening, so as to provide a reference for exploring the deformation and energy consumption characteristics of the combined tube in engineering applications. When setting, the cross-sectional size of the opening is set to be smaller than the cross-sectional size of the rectangular groove, and the size of the ram is set to be suitable for the size of the opening. In this way, when the driving assembly 3 drives the top die 1 to make the ram extend into the rectangular groove to compress the several circular tubes 6, only the part of the circular tubes 6 which is suitable for the cross-sectional size of the opening can be contacted, and the circular tubes 6 in the rectangular groove which do not overlap with the opening in the cross-sectional size and the normal projection will not be directly extruded by the ram, thereby achieving the technical purpose of locally compressing the several circular tubes 6, and further providing a reference for exploring the deformation and energy consumption characteristics of the combined tube in engineering applications.

[0035] In some possible embodiments, the bottom die 2 comprises: a horizontal plate 201; a first vertical baffle 202 fixedly arranged on one side of the upper surface of the horizontal plate 201; a second vertical baffle 204 fixedly arranged on the other side of the upper surface of the horizontal plate 201 and oppositely distributed with the first vertical baffle 202, the horizontal plate 201, the first vertical baffle 202 and the second vertical baffle 204 forming a rectangular groove; a first horizontal baffle 203, one end of the first horizontal baffle 203 being arranged on the side wall of the first vertical baffle 202 in the height direction of the first vertical baffle 202 and being slidable in the height direction of the first vertical baffle 202; and a second horizontal baffle 205, one end of the second horizontal baffle 205 being arranged on the side wall of the first vertical baffle 202 in the height direction of the first vertical baffle 202 and being slidable in the height direction of the first vertical baffle 202, the other end of the second horizontal baffle 205 corresponding to the other end of the first horizontal baffle 203 and forming an opening.

[0036] For the bottom die 2, the first vertical baffle 202 and the second vertical baffle 204 are arranged on the opposite sides of the upper surface of the horizontal plate 201 as a rectangular groove structure, and then the first horizontal baffle 203 and the second horizontal baffle 205 are correspondingly arranged at the opposite positions in the opposite direction of the first vertical baffle 202 and the second vertical baffle 204 to form an opening, so that the cross-sectional size of the opening is smaller than the cross-sectional size of the rectangular groove; and the first horizontal baffle 203 and the second horizontal baffle 205 can be displaced in the height direction of the first vertical baffle 202 and the second vertical baffle 204, so that the height of the first horizontal baffle 203 and the second horizontal baffle 205 can be adjusted according to the number of layers of the circular tubes 6 arranged.

[0038] For the sliding mode of the first horizontal baffle 203 and the second horizontal baffle 205 in the first embodiment, the first embodiment provides an implementation manner, which comprises: the first sliding groove 20201 and the second sliding groove are arranged on the first vertical baffle 202 and the second vertical baffle 204, the first horizontal baffle 203 and the second horizontal baffle 205 are connected by the first threaded rod 7 and the second threaded rod passing through the sliding grooves, and the positions of the first threaded rod and the second threaded rod outside the first sliding groove 20201 and the second sliding groove are correspondingly provided with the first nut 701 and the second nut with a width greater than the first sliding groove 20201 and the second sliding groove, so that when the first threaded rod and the second threaded rod are screwed to a preset progress, the first nut 701 clamps the first vertical baffle 202 with the first horizontal baffle 203, and the second nut clamps the second vertical baffle 204 with the second horizontal baffle 205, thereby achieving the purpose of locking the first horizontal baffle 203 and the second horizontal baffle 205 in a temporary fixed position.

For example, in a long-term test, the first vertical baffle 202 and the second vertical baffle 204 are extruded loose from the corresponding installation position, and then separated, so that the transverse pull rod is arranged between the two to enhance the connection stability of the two.
