Study of vibration damping with dry friction snubber on blade platform

A simplified method using transfer matrix method was applied to the analysis and calculation of the vibration damping effect induced by dry friction snubber on the blade platform. To validate the calculated results of the transfer matrix method, the finite element method AN-SYS was used to calculate blade vibration with dry friction damper on the platform. The calculated results of the two methods are basically consistent, which demonstrates that the transfer matrix method suitable for chain-construction-system can also be applied to the plate-construction-system.
