| description | The invention discloses a test device capable of testing a bolt loosening behavior under a multi-angle load effect. The device is mainly composed of an annular clamp, a pair of U-shaped sleeves, a pressure sensor, a to-be-tested bolt, a to-be-tested nut, fastening bolts, fastening nuts, a gasket and the like. A bolt hole is formed in the center of a square contact area of the annular clamp, and the to-be-tested bolt can penetrate through the bolt hole to complete the assembly of a pair of annular clamps and the pressure sensor. Equal-angle bolt holes distributed along the axis are formed in anannular area of the annular clamp, and the holes of different angles can be connected with the U-shaped sleeves through the fastening bolts and nuts according to needs. Square bulges at the bottoms of the U-shaped sleeves can be clamped by a hydraulic clamping device of a fatigue tensile tester. Finally, a multi-angle load loosening test can be carried out. The device not only can support axial load and transverse load t |
