Embodiment 1
[0060] This embodiment includes: an external pressure loading device, a thermal loading device, and a cross-sectional shear loading device; the external pressure loading device includes: a pressurizing bladder, a gas pressurizing system, and a liquid filling system, and the pressurizing bladder is charged by the liquid filling system. After injecting liquid and pressurizing through the gas pressurization system, it deforms toward the test piece 10 and compresses the test piece 10. The test piece 10 is connected to a heat loading device and heated by the heat loading device. The cross-sectional shear loading device includes a plurality of shear loading lever sets , the shear loading lever group is installed in the test piece 10 and applies shear force to the test piece 10, and the external pressure loading device, the thermal loading device and the cross-section shear loading device are connected to the test system terminal 15.
[0061] like figure 1 As shown, the external pres...
Embodiment 2
[0067] Example 2 is a preferred example of Example 1.
[0068] like Figure 1 to Figure 3 As shown, this embodiment includes: an external pressure loading device, a thermal loading device and a cross-sectional shear loading device. The external pressure loading device consists of air source 1, pressure reducing valve 2, booster valve 3, pressure relief valve 4, pressure relief port 5, rear pressure bearing tool 6, front end pressure bearing tool 7, front pressure booster bag 8, rear end The pressurized bladder 9 , the test base 11 , the pressure gauge 12 , the pressure sensor 13 , the pressure test line 14 , the test system terminal 15 , the filling pipeline 16 , the filling valve 17 , and the water source 18 are composed. The heat loading device is composed of a front-end electric heating blanket 19 , a rear-end electric heating blanket 20 , a temperature sensor and a test line 21 , and a test system terminal 15 . The cross-section shear loading device is composed of a fron...
Embodiment 3
[0075] like Figure 1 to Figure 3 As shown, the test piece 10 is installed on the test base 11, and the front-end pressurizing bag 8 and the rear-end pressurizing bag 9 are installed in the following manner: the front-end pressurizing bag 8 is installed inside the front-end pressure-bearing tool 7, and the front-end pressure-bearing tool 7 The inner wall surface is pasted with a flexible felt material to prevent the hard wall surface from damaging the front-end pressurizing bladder 8 during the pressurization process. Similarly, the rear pressure boosting bag 9 is installed inside the rear pressure bearing tool 6, and the inner wall of the rear pressure bearing tool 6 is pasted with a flexible felt material to prevent the hard wall from damaging the rear pressure bag 9 during the pressurization process. The rear-end pressure-bearing tooling 6 and the front-end pressure-bearing tooling 7 are both fixedly connected to the connecting ring by bolts, and the rear-end pressure-beari...
