[0014] The system for constructing an in-situ mechanical property model of materials driven by CT scanning data includes the following steps:
[0015] S1. When CT scanning is needed to construct a data-driven in-situ mechanical property model of materials, the operator can place the object to be scanned by CT inside the scanning body, perform azimuth scanning of the object through the semi-circular guide rail slide and the scanning end, and then convert the scanned data into numerical signals with the cooperation of the converter and transmit them to the distributed array processor. Then, the distributed array processor forms a three-dimensional object numerical signal with the cooperation of the three-dimensional modeling software and transmits it to the D-printed body for printing. Then, the printing is divided into four groups of comparative cases, namely a1, a2, a3 and a4. First, a1 is used as an ordinary sample, gypsum powder is used, and the gypsum powder is selectively sintered by the laser printing end. After each layer is sintered and formed, the layers are stacked to form a three-dimensional entity. Then, the printed 3D object is placed in the mechanics laboratory under the transportation of the operator;
[0016] S2, then, use a2 to print the comparative case operation. a2 uses photosensitive resin powder. After the photosensitive resin powder is transported to the 3D printing body by the feeding end, the photosensitive resin powder is sintered by the laser printing end in the presence of an adhesive to form a single layer printing operation, that is, the 3D printing body sprays the adhesive on the photosensitive resin powder according to the predetermined cross-sectional shape of the processing display to bond it, completing the first layer printing, and then the molding cylinder is lowered by one layer thickness, and the powder spreading roller inside the powder feeding structure spreads powder again, and then bonding is performed, and the above process is repeated until the entire comparative case sample is printed;
[0017] S3, then use a3 to perform a printing comparison operation, a3 uses polyimide and fluororesin combined powder, and uses the feeding end again to transport the polyimide and fluororesin combined powder to the 3D printing body, and uses the powder feeding structure to feed and spread the polyimide and fluororesin combined powder in advance, forming a printing matrix at the laser printing end, and then, with the cooperation of the particle emission body, use the same particle emission channel to transport charged same-sex particles to the printing matrix, and synchronously perform 3D object printing operations, and then use a4, a4 synchronously uses polyimide and fluororesin combined powder, and after the same printing operation process as above, with the cooperation of the particle emission body, use the opposite-sex particle emission channel to transport opposite-sex charged particles to the printing matrix;
[0018] S4. Afterwards, the operator puts the four groups of printed objects into the mechanics laboratory, and drives the mobile test table to slide and adjust to the side of the mechanics laboratory on the top surface of the sliding platform with the help of the adjusting guide rail. When it reaches the preset position, the small hydraulic rod drives the resonance plate to rotate with the help of the insulating shaft, and closes the mechanics laboratory. With the help of the servo control motor start-up, the driving gear, the first forward gear, the second forward gear and the two sets of racks are used to drive the driver and the uniaxial compressor to construct the mechanical property model of the four groups of printed objects.

[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. In the present invention, by cooperating with a particle emission body, a homogeneous particle emission channel, a heterogeneous particle emission channel, an infrasonic generator and an infrasonic frequency modulator, it is convenient to drive the rotating shaft seat to adjust its position under the cooperation of a double-axis pneumatic cylinder, and it is convenient for the rotating arm to adjust the position of the infrasonic frequency modulator and the sound source end under the rotation adjustment of the rotating shaft seat, and under the cooperation of the infrasonic frequency modulator, it is convenient to modulate the emitted sound waves at different frequencies, and then, under the cooperation of a resonance plate, resonate four groups of printed objects, so as to detect different peak values of the mechanical properties of the four groups of printed objects, and then construct a mechanical property model, and in the different conveying printing operation detection processes of the homogeneous particle emission channel and the heterogeneous particle emission channel, it is convenient to use the different characteristics of charged homogeneous particles and heterogeneous charged particles to further perform mechanical experimental detection on the four groups of printed objects under different stress conditions, thereby improving the overall use effectiveness and facilitating operators to intuitively understand the structural characteristics of relevant mechanical properties.
[0021] 2. In the present invention, by cooperating with the control and adjustment component and the optical fiber position sensor, it is convenient to drive the active gear to rotate under the cooperation of the servo control motor, so that the first forward gear and the second forward gear rotate synchronously, so that the first forward gear and the second forward gear, under the cooperation of two sets of racks, drive the installation connection seat, the single-axis rod and the single-axis compressor to adjust the position and then limit the position adjustment, so as to facilitate the subsequent mechanical property detection operation. After constructing different mechanical models, the formed data dynamic model is transmitted to the distributed array processor and the processing display for observation by the operator.
[0022] 3. In the present invention, with the cooperation of the adjustment component, it is convenient to drive the mobile experimental table to slide and adjust on the top surface of the sliding table to the side of the mechanical laboratory with the cooperation of the adjustment guide rail. When it reaches the preset position, the rotating motor drives the small hydraulic rod to rotate the angle inside the rotating seat. The small hydraulic rod drives the resonance plate to rotate with the cooperation of the insulating rotating shaft. When the small hydraulic rod is working, the rotating seat is displaced inside the engaging slide groove with the cooperation of the return spring to avoid the different heights of the resonance plate and the installation groove during the subsequent rotation and covering, which causes obstruction to the displacement of the mobile experimental table. At the same time, the small hydraulic rod drives the resonance plate to rotate with the cooperation of the insulating rotating shaft, and performs a closed operation with the mechanical laboratory, and further cooperates with the infrasonic generator and the infrasonic frequency modulator to construct mechanical property models for four groups of printed objects.

[0044] The method of using the device and the working principle are as follows: first, when CT scanning is needed to construct a data-driven in-situ mechanical property model of a material, the operator can place the object to be CT scanned inside the scanning body 31, and perform an azimuth scanning operation on the object through the semi-circular guide rail slide 32 and the scanning end 33. Then, the scanned data is converted into a numerical signal with the cooperation of a converter and transmitted to the distributed array processor 20. Then, the distributed array processor 20 converts the received converted numerical signal into a three-dimensional object numerical signal with the cooperation of a three-dimensional modeling software (such as Rhino and AutoCAD) and transmits it to the 3D printer body 19 for printing. Then, the printing is divided into four groups of comparison cases, namely a1, a2, a3 and a4, first use a1 as a common sample, use gypsum powder, use the laser printing end 24 to selectively sinter the gypsum powder, after each layer is sintered and formed, stack the layers to form a three-dimensional entity, and then put the printed 3D object into the mechanics laboratory 22 under the operator's transportation. Then, use a2 to print a comparative case operation. a2 uses photosensitive resin powder. After the photosensitive resin powder is transported to the 3D printer body 19 by the feeding end 6, the photosensitive resin powder is sintered by the laser printing end 24 with the help of the adhesive to form a single layer printing operation, that is, the powder feeding structure 17 and the molding cylinder 18 are used to make the 3D printer body 19 spray the adhesive on the photosensitive resin powder according to the predetermined cross-sectional shape of the processing display 21. Bonding, complete the first layer of printing, then make the forming cylinder 18 drop one layer thickness, the powder spreading roller inside the powder feeding structure 17 spreads powder again, and then bonding is performed, and the above process is repeated until the entire comparison case sample is printed. Then, a3 is used for printing comparison operation. a3 uses polyimide and fluororesin combined powder, and the feeding end 6 is used again to transport the polyimide and fluororesin combined powder to the 3D printing body 19. The powder feeding structure 17 is used in advance to feed and spread the polyimide and fluororesin combined powder. A printing matrix is formed at the laser printing end 24, and then, with the cooperation of the particle emission body 16, the charged isotropic particles are transported to the printing matrix using the isotropic particle emission channel 10, and the 3D object printing operation is performed simultaneously, and then the particle emission body 16 is used. a4, a4 synchronously uses polyimide and fluororesin combined powder. After the same printing operation process as above, with the cooperation of the particle emission body 16, the oppositely charged particles are transported to the printing matrix by using the oppositely charged particle emission channel 25. Then, with the cooperation of the adjustment guide rail 23, the mobile experimental table 2 is driven to slide and adjust on the top surface of the sliding platform 1 to the side of the mechanical laboratory 22. When it reaches the preset position, the rotating motor 76 drives the small hydraulic rod 74 to rotate the angle inside the rotating seat 75.
