Vibration Test and Analysis on Medium-Speed Mill-Foundation Coupled System

Abstract:

To evaluate the vibration performance of medium-speed mill-foundation coupled system, eight mills in five thermal power plants were tested in site. The vibration displacement and acceleration of upper and lower bedplates of foundations and equipment bodies were measured. According to the test results, the vibration safety of mills is evaluated. The study shows that the vibration displacement of medium-speed mill with spring vibration-isolated foundation meets the code requirements, but the vibration displacement of equipment body is larger. The vibration displacement of equipment body should be controlled by limiting the vibration displacement of foundation platform in design.
