Embodiment 1
[0025] Embodiment 1 A description of the structure of a dynamic split-pull loading test device suitable for CT scanning according to the present invention
[0026] Such as figure 1 , figure 2 As shown, a dynamic split-pull loading test equipment suitable for CT scanning includes a tension platform 1, a tension-compression conversion mechanism 2, a steel rod 3, a pressure platform (pressing end) 4, a universal head 5, a specimen 6, Constraint platform (fixed end) 7, load and displacement sensor 8, computer control system 9.
[0027] The hydraulic stretcher, pressure and displacement sensors 8 and computer control system 9 connected externally to the tension platform 1 constitute the load application control system of the equipment.
[0028] The tension platform 1 and the pressure platform 4 are connected through the tension-compression conversion mechanism 2, and the tension-compression conversion mechanism 2 transmits the load of the tension platform 1 to the pressure platf...
Embodiment 2
[0034] Embodiment 2 A method of using the dynamic splitting and pulling loading test equipment suitable for CT scanning according to the present invention
[0035] The specific test steps are as follows:
[0036] Step 1, place and adjust the equipment: fix the equipment constraining platform 7 on the bed of the CT scanner, and adjust so that the length direction of the steel rod 3 is parallel to the direction of the scanning section;
[0037] Step 2, installation of the loading and measuring system: connect the hydraulic tensioner to the tension platform 1 at both ends, install the pressure and displacement sensor 8 and connect it to the computer;
[0038] Step 3, setting of experimental parameters: select the control loading mode of the test (load control or displacement control), set the initial parameters (displacement initial parameters x 0 or the initial parameter of the force F 0 , for pre-clamping specimens), incremental parameters (displacement incremental paramete...
