A set of intelligent correction equipment for gas pipelines was developed for the problem of gas pipeline settlement caused by coal mining subsidence. The modal simulation analysis of the device was carried out by using SolidWorks and ANSYS Workbench engineering software. The analysis results show that the first six modal frequencies of the intelligent correction device increase with the increase of the order, and are in the first, second, third and sixth of the equipment. The torsion phenomenon occurs in the order, and a strip deformation occurs on the large wheel of the transmission module. After the modal simulation analysis, the modal test was carried out, and the experimental data was compared with the simulation data. It was known that the data obtained by different test methods of the intelligent correction device had little difference, which proved that the data has strong reliability. Finally, in order to understand the vibration characteristics of the intelligent orthodontic equipment, the vibration test of the equipment was carried out. The experimental results show that the vibration frequency of the equipment is concentrated around 053 Hz, 5006 Hz, 8097 Hz, 9992 Hz, 17138 Hz, 19465 Hz, and equipment. The natural frequencies are very different, which ensures that the intelligent correcting device does not resonate during operation.
