[0050] A method for using an automatic continuous shear wave excitation source device comprises the following steps:
[0051] S1. The length of the plug-in stabilizing cone rod 34 is adjusted by the limit pin 33. When the length reaches the specified length, the limit pin 33 is locked. Then, the positioning ring block 32, the limit pin 33, and the plug-in stabilizing cone rod 34 are inserted into the specified position, thereby continuously supporting the entire excitation structure 1, the drive control structure 2, and the combined structure 3. At the same time, the transmission rod 31 is also inserted;
[0052] S2. When it is a single-point simulation, the control motor 13 is working at this time, and the control motor 13 drives the active gear disc 12 to rotate, and the active gear disc 12 is meshed with the second tooth block 21 at the lower end of the connecting disc 20, thereby driving the connecting disc 20 to rotate as a whole. When the connecting disc 20 rotates, the first tooth block 19 at the upper end is driven to rotate along, and the first tooth block 19 is meshed and connected with the driven gear disc 10, thereby driving the driven gear disc 10 and the rotating rod 9 to rotate at the center of the column frame 11. The rotation of the rotating rod 9 drives the second hinge rod 8 to rotate along, thereby changing the position of the first hinge rod 6 by cooperating with the plug block 7, and the excitation push rod 15 at the lower end is limited by the sleeve frame 22 and the sleeve 27, thereby driving the excitation push rod 15 to reciprocate;
[0053] S3, when the excitation push rod 15 reaches the bottom position, it contacts the first matching tube 28, generates a shock force, and transmits it through the transmission disc seat 36, thereby simulating the vibration source;
[0054] S4. When multi-point testing is required, the hydraulic control seat 24 works at this time. By changing the internal oil pressure, the telescopic length of the telescopic control rod 26 is changed, so that the bottom end of the telescopic control rod 26 contacts the second matching cylinder 29, generating a shock force. At the same time, the telescopic control rod 26 and the second matching cylinder 29 are provided with multiple ones to perform multi-point simulation work. The shock force of the second matching cylinder 29 can be transmitted and conducted through the transmission end seat 30 and the transmission rod 31, which is convenient for test and detection work.
[0055] Working principle: When work is needed, the user assembles the continuous excitation structure 1, the drive control structure 2, and the combined structure 3, and then installs the continuous excitation structure 1, the drive control structure 2, and the combined structure 3 at a suitable position. First, the length of the plug-in stabilizing cone rod 34 is adjusted by the limit pin 33. After reaching the specified length, the limit pin 33 is locked, and then the positioning ring block 32, the limit pin 33, and the plug-in stabilizing cone rod 34 are inserted into the specified position, thereby supporting the continuous excitation structure 1, the drive control structure 2, and the combined structure 3 as a whole, and the transmission rod 31 is also inserted;
[0056] When a test is required, the test type is determined at this time. When it is a single-point simulation, the control motor 13 is operated at this time, and the control motor 13 drives the active gear disc 12 to rotate, and the active gear disc 12 is meshed with the second tooth block 21 at the lower end of the connecting disc 20, thereby driving the connecting disc 20 to rotate as a whole. When the connecting disc 20 rotates, the first tooth block 19 at the upper end is driven to rotate along, and the first tooth block 19 is meshed and connected with the driven gear disc 10, thereby driving the driven gear disc 10 and the rotating rod 9 to rotate at the center of the column frame 11. The rotation of the rotating rod 9 drives the second hinge rod 8 to rotate along, thereby changing the position of the first hinge rod 6 through the matching plug block 7;
[0057] And the excitation push rod 15 at the lower end is limited by the sleeve frame 22 and the sleeve 27, thereby driving the reciprocating movement of the excitation push rod 15 to achieve continuous regulation. When the excitation push rod 15 reaches the bottommost position, it contacts the first matching cylinder 28 to generate a shock force, which is then transmitted through the transmission disc seat 36 to simulate the vibration source. When multi-point testing is required, the hydraulic control seat 24 works at this time, and the telescopic length of the telescopic control rod 26 is changed by changing the internal oil pressure, so that the bottom end of the telescopic control rod 26 contacts the second matching cylinder 29 to generate a shock force. At the same time, the telescopic control rod 26 and the second matching cylinder 29 are provided with multiple ones to perform multi-point simulation work. The shock force of the second matching cylinder 29 can be transmitted and transmitted through the transmission end seat 30 and the transmission rod 31, which is convenient for test and detection work to complete the work.
