At present, a shield process is generally simulated by adopting a model test mode so as to analyze the vibration response of the cutter head 4 and the stratum. Because the tunneling angles of the existing experimental models are all in an ideal horizontal direction, and because of the complexity of the stratum environment, the shield tunneling angle needs to be adjusted in real time. Under different tunneling angles, the vibration response state of the cutter head 4 and the stratum can be greatly different. The existing experimental model can only simulate and obtain the vibration response of the cutter head 4 and the stratum under the condition of a single tunneling angle, and the effect is poor.
In order to solve the above problem, as shown in fig. 1, this embodiment discloses an experimental apparatus for shield cutterhead vibration response, so as to simulate the shield process at different tunneling angles, thereby measuring the vibration response of the cutterhead 4 and the soil layer at different tunneling angles.

In this embodiment, a soil layer is laid in the soil box 1 to simulate a shield environment. The tunnel mould 3 extends into the soil box 1, a cutter head 4 is arranged at the end part extending into the soil box 1, and the driving piece 5 can drive the cutter head 4 to rotate and slide along the tunnel mould 3 so as to simulate tunneling operation. Because the position of the tunnel mould 3 on the bracket 2 is adjustable, the inclination angle of the tunnel mould 3 is adjustable, and the cutter head 4 has different tunneling angles. The vibration response measuring assembly can measure the vibration response of the cutter head 4 and the soil layer at different tunneling angles, the simulation range and the simulation effect of the experimental device for the shield cutter head vibration response are improved, and the accuracy of the vibration response measurement of the cutter head 4 and the soil layer is improved.
As shown in fig. 1 and 2, the experimental apparatus for shield cutterhead vibration response further comprises a base 10, and the soil box 1 and the support 2 are both arranged on the base 10. The projection of the soil box 1 along the vertical direction falls on the base 10, that is, the length and the width of the base 10 are respectively greater than the length and the width of the soil box 1. When the cutter head 4 is in the tunneling process, all soil overflowing from the soil box 1 falls on the base 10, so that collection and arrangement are facilitated, and the influence on the environment around the experimental device for shield cutter head vibration response is avoided.

The mounting plate 32 is located within the barrel 31 and is integrally formed with the barrel 31. A through hole is formed in the mounting plate 32, the screw hole block 33 is provided with a screw hole penetrating through the screw hole block 33, the screw hole block 33 is fixedly mounted on the mounting plate 32 through a bolt, and the through hole and the screw hole are coaxially arranged.
The cutter head 4 of the present embodiment includes a cutter head body 41 and a connecting rod 42, and one end of the connecting rod 42 is fixedly connected to the center of the cutter head body 41. The driving piece 5 is a variable-frequency speed-regulating motor, has the advantages of high transmission efficiency, low noise and good reliability, and can accurately control and adjust the rotating speed of the cutter head 4. The output shaft of the variable frequency speed regulating motor is connected with a screw rod 51, and the screw rod 51 is connected with the connecting rod 42 through a flange structure after sequentially passing through the through hole and the threaded hole.

When tunnel mould 3 angle of adjustment, protective sheath 9 avoids taking place too big wearing and tearing volume between protection tunnel mould 3 and the soil box 1, plays the guard action.
In particular, the protective sheath 9 is a rubber sheath with good elasticity. When the tunnel mold 3 tunnels in the horizontal direction, the tunneling angle is zero, and the gap between the tunnel mold 3 and the through hole of the soil box 1 is the largest. When the tunnel mold 3 tunnels in the oblique direction, the tunneling angle is not zero, and the gap between the tunnel mold 3 and the through hole of the soil box 1 becomes small. It will be appreciated that the greater the absolute value of the heading angle, the smaller the clearance between the tunnel mould 3 and the through-hole of the soil box 1. Therefore, the rubber sleeve with elasticity can adapt to the change of the gap between the tunnel mold 3 and the through hole of the soil box 1 when the angle is adjusted, and the tunnel mold 3 and the soil box 1 can be kept well sealed.
In the actual measurement process, proper vaseline is smeared between the protective sleeve 9 and the tunnel mold 3, so that a good sealing effect can be achieved, and soil in the soil box 1 can be further prevented from overflowing from the through hole, the protective sleeve 9 and the tunnel mold 3.
