Abstract

An airtight and compressive load test device for a curved plate, comprising an upper press table (1), a curved plate test piece (2), a test fixture assembly (3), and a lower press table (4), wherein the test fixture assembly (3 ) is a symmetrical structure, the test fixture assembly (3) and the curved plate specimen (2) are arranged between the lower press table (4) and the upper press table (1), and the test fixture assembly (3) is fixedly connected by bolts. Press table (4), curved plate test piece (2) coincides with the center line of upper press table (1), lower press table (4). The curved plate airtightness and compression load test device of the present invention can accurately simulate the boundary conditions of the curved plate test piece (2) on both sides of the curved plate under the action of airtight load, the load transmission route is clear, the load is accurate, and the structure of the device is simple , The installation is quick and does not require additional support for the curved plate test piece (2) and the test fixture assembly (3), which shortens the test period and improves the test efficiency.

Description

technical field [0001] The invention relates to the technical field of structural strength tests, in particular to an airtight and compressive load test device for curved plates, which is used for static force and fatigue tests of curved plate structures under the action of airtight and compressive loads. Background technique [0002] In the structural design of aerospace vehicles, in order to improve the stability of the structure, the form of stringers and skins is often used. Therefore, the stiffened curved plate is a typical structure in aerospace structures. During the flight of the aircraft in the atmosphere, due to the pressure difference between the inside and outside of the wall plate, the wall plate bears the normal airtight load. The compression stability and strength of stiffened curved plates under airtight loads are very important research topics in the study of structural strength. In order to verify the rationality of the structural design and the accuracy o...
