Abstract
The invention discloses a vibration aging treatment method for a railway traffic equipment large metal component. The method includes the following steps that the large metal component is installed on a vibration test table; the positions of a vibration test control point and a responding point are determined; a sine scanning vibration test is performed on the large metal component; the resonant frequency of the large metal component is determined; resonant frequency point fixed-frequency sine vibration aging treatment is performed on the large metal component; wide band random vibration aging treatment is performed on the large metal component; and the vibration aging treatment in the vertical direction, the transverse direction and the longitudinal direction of the large metal component is completed. The vibration aging treatment method for the railway traffic equipment large metal component can fast and effectively eliminate the remaining stress of the large metal component.
