The displacement sensor 32 may also be connected to the control device 6, and the control device 6 may receive displacement data collected by the displacement sensor 32 in real time, and may perform data processing on the displacement data, for example, may calculate the maximum deformation (i.e., deflection) of the bottom surface of the test plate 7 and calculate the residual deformation of the test plate 7 according to the displacement data.
Step S4, the control device 6 controls the sliding support 3 to drive the test plate 7 to reciprocate on the guide rail 2.
After the steps 1-3 are completed, the control device 6 starts the motor 31 connected with the sliding support 3 and the limiting device 21, so that the sliding support 3 drives the test plate 7 to reciprocate on the guide rail 2.
Step S5, the control device 6 receives the data collected by the displacement sensor 32 and the limiting device 21, and processes the data.
The data collected by the displacement sensor 32 is displacement change data of the bottom surface of the test plate 7, the limiting device 21 has a counting function, and the collected data is the number of times that the sliding support 3 reciprocates on the guide rail 2, that is, the number of times that the test plate 7 rolls through the rolling wheel 41.
Step S6, if the maximum displacement value acquired by the displacement sensor 32 exceeds the preset displacement value, or the cycle number acquired by the limiting device 21 reaches the preset cycle number, the control device 6 controls the sliding support 3 to stop moving; if the maximum displacement value acquired by the displacement sensor 32 exceeds a preset displacement value, recording the cycle times acquired by the limiting device 21; and if the cycle times collected by the limiting device 21 reach the preset cycle times, recording the maximum displacement value collected by the displacement sensor 32.
The number of cycles described in the above step 6 means the number of times the sliding support 3 reciprocates on the guide rail 2.
