Example Embodiment

[0013] Such as figure 1 , 2 As shown in 3, the enclosed frame is composed of a rigid base 1, four uprights 2, a rear cross beam 8, an upper cross beam 7, a load loading plate 5, an oil cylinder, etc. Equipped with multiple hydraulic cylinders in the X, Y, and Z directions as the force applying mechanism. The rigid base 1, the four columns 2, the rear cross beam 8, and the upper cross beam 7, are all welded by steel plates, and then bolted to form a closed frame. The column 2 is bolted to the rigid base 1. The load loading plate 5 is connected with the sample 3 to be tested.

[0014] The rigid base 1 is connected with the four uprights 2 by bolts. In the front view, the two left uprights 2 are connected together by bolts through a vertical connecting beam 9, and the right two uprights 2 in the front view are also connected together by a vertical connecting beam 9 by bolts. The upper beam 7 and the four uprights 2 are connected by bolts. The rear cross beam 8 is connected with ...

Abstract

The invention belongs to a design method and particularly relates to an enclosed loading framework for a multidimensional bearing test on a large-scale structural member. The enclosed loading framework comprises a rigid foundation and further comprises four columns an upper cross beam, wherein the rigid foundation and the upper cross beam are respectively connected with the columns through screws to form a generally hollow cube shape, and the upper cross beam is provided with a z-direction oil cylinder. The enclosed loading framework is advantaged in that the enclosed loading framework is an internal force self-balancing system capable of improving measurement precision, multidimensional cooperation loading is further realized, and the enclosed loading framework is further equipped with multiple hydraulic oil cylinder driving systems to realize x, y and z multidimensional pulling, pressing and twisting simulation loading of a large-scale sample. For a small sample, only a pulling, pressing or twisting single condition test can be realized through a traditional design method. The enclosed loading framework can realize the cooperation loading test on a large-scale structural member under the pulling, pressing and twisting composite bearing condition.

Description

technical field [0001] The invention belongs to a design method, in particular to a closed loading frame for multi-dimensional force testing of large structural parts. Background technique [0002] With the continuous development of nuclear technology, new technologies are constantly being applied to various nuclear devices. Due to the high safety requirements of nuclear devices, the safety of structural components or devices cannot be guaranteed only with the current finite element mechanical analysis software. The finite element mechanical analysis software can effectively help the designer consider the impact of the weak links of mechanical parts on the entire machine equipment in the early stage of mechanical design, and the finite element optimization design method analyzes important parts and the whole machine to find out the weak links , optimize the design of the weak part of the mechanical parts, which has certain guiding significance for improving the reliability ...
