Embodiment 1
[0081] Combine below Figure 1 to Figure 11 As shown, Embodiment 1 of the present invention provides a single-rod pull-type vibrating table test device for characterizing centrifugal force, including an electromagnetic vibrating table 1, and also includes a receiving plate 2, a fixture platform 3, a fixture 4, a fixing part 5, and a tensile force Meter pedestal 6, tensile gauge 7 and analog component 8, the receiving plate 2 is arranged on the electromagnetic vibrating table 1, and the receiving plate 2 is fixedly connected with the table surface of the electromagnetic vibrating table 1 through eight-hole bolts, and the fixture platform 3 is slidably set Above the receiving plate 2, the clamp 4 is arranged above the clamp platform 3, the clamp 4 includes a male clamp 41, a female clamp 42 and a blade clamping groove 43, the male clamp 41 is arranged on the clamp platform 3, The female splint 42 is engaged and connected above the male splint 41, the inside of the female splint ...
Embodiment 2
[0093] Depend on figure 2 with Figure 5 As shown, Embodiment 2 of the present invention provides a single-rod pull-type vibration table test device for characterizing centrifugal force. The difference from Embodiment 1 is that the simulation component 8 includes a reaction force column 801, a latch 802, Guide rod 803 and scale bolt holes 804, the reaction force column 801 is fixedly arranged on the receiving plate 2, one end of the guide rod 803 is connected to one end of the tension gauge 7, and several scale bolt holes 804 are arranged in an array on the guide rod 803 , the latches 802 can be movably connected with several scale bolt holes 804 respectively.
[0094] When working, pull the guide rod 803 towards the opposite direction of the tension meter 7, observe the value on the tension meter 7, insert the latch 802 into the scale bolt hole 804 for fixing after the value is suitable, and pull out the latch 802 after the vibration test is completed The fixing is cancele...
Embodiment 3
[0096] This embodiment provides a test method based on the single-rod pull-out vibration table test device for characterizing centrifugal force in Embodiment 1 and Embodiment 2.
[0097] When working, put one end of the tenon of the blade into the blade clamping groove 43, press down the female splint 42 so that the male splint 41 and the female splint 42 are engaged, and at the same time the female splint 42 and the male splint 41 engage the tenon end of the blade. Clamping and fixing, adjusting the height of the fixture platform 3 facilitates the mating connection between the blade and the tension gauge 7. After the height adjustment is completed, use the fixing part 5 to fix the fixture 4. After the fixing is completed, connect the analog part 8 to the other end of the blade. The simulation part 8 adjusts the pulling force on the blade, thereby simulating the centrifugal force of different strengths. After all the adjustments are completed, the electromagnetic vibrating tabl...
