Abstract
The invention provides a three-direction loading system and method for cylindrical products. The three-direction loading system comprises a product installation bracket(2), an X-direction hydraulic actuating cylinder and force sensor (3), an X-direction loading device (4), a Y-direction loading device (5),a Y-direction hydraulic actuating cylinder and force sensor (6), a Y-direction hydraulic actuating cylinder fixing lever (7), a Z-direction loading device (8), a Z-direction hydraulic actuating cylinder and force sensor (9), and a Z-direction hydraulic actuating cylinder fixing load-bearing column (10). According to the three-direction loading system and method for the cylindrical products, the synchronous loading requirement of the cylindrical products with different sizes in the directions of X, Y and Z are satisfied, through three sets of loading devices with simple structure, convenient disassembling and assembling, and easy processing and manufacturing, and while the test cost and the test workload are reduced, the test efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of strength testing, in particular to a three-way loading system and method applied to cylindrical products. Background technique [0002] In the strength test tasks of aerospace products, many three-dimensional test items of cylindrical structural products are involved. Due to the need to apply loads in three different directions at the same time during the test, and the loads of different types of products are very different, it is necessary to prepare a set of three-way loading devices for each test according to the size and direction of the load, which not only consumes a lot of time Human and financial resources, but also consume a lot of installation time. Therefore, it is necessary to design a universal three-way loading device that can be applied to different types of cylindrical products, so as to save costs, improve efficiency, and effectively promote the smooth progress of the test.
