  • The macro-micro slip model was used to analyze vibration response of plate blades with a dry friction damping.Compared to the experimental results,the analytical method was proved to be feasible.Non-dimensional normal force was defined,and by the use of it,the relationship between the vibration responses and non-dimensional normal force of the plate blades with a dry friction damper were obtained.The calculation results indicate that in the micro-slip stage,the friction damper can markedly reduce the responses of the vibration system,so that the introduction of micro-slip model is very important,and the non-dimensional normal force can be used as a design variable of dry friction dampers to optimize parameters of damper making the response of a vibration system to be minimum while resonance occurs.
