Embodiment 1
[0067] 1. Debug the device in the air outside the wave flow tank;
[0068] 2. Apply multiple known definite displacement values to the simulated pipeline, and record the corresponding voltage value of the laser displacement sensor, and obtain the calibration coefficient of the laser displacement sensor by fitting the displacement and the corresponding voltage value;
[0069] 3. To measure the structural damping of the device, the basic operation is as follows: a. Apply a known displacement excitation to the cylinder and release it, allowing it to freely attenuate the vibration; b. Record the change of the vibration displacement of the cylinder with time; c. Matching theoretically predicted responses with experimental records to find unknown damping;
[0070] 4. Hoist the device into the experimental section of the wave flow tank, add water to the water tank to the test water depth, and adjust the distance between the pipeline and the bed surface. Measuring the natural frequ...
