Abstract:The vibration response analysis program of a turbine blade is developed by using the two-dimensional macro-micro slip model. The influence factors of reducing the vibration response, such as the normal force and the exciting force, are achieved by calculating example. The results show that at the same exciting force, there is a normal force which makes the response decrease effectively. The exciting force is important to reduce the vibration response of dry friction damping. In addition, introducing the friction damper can also modulate the natural frequency of the blade system.
