摘要
A blast furnace top gas recovery turbine （TRT） device is af/ected by the Jbrce of steady-state flow and nonsteady-state interaction so that the working-station is poor. A damper which is made of metal rubber is designed to improve stabilization of the blade of the TRT, and to reduce vibration of the TRT.The damping blade of the TRT is analyzed about its static stress and displacement, modal and transient in ANSYS. The results are contrasted. The result indicates that the damper can reduce inherent failure of the blade, and dynanffc-stress. The structure of the damper is simple, and easy to be made.
