Friction damper is widely used in civil engineering because of its excellent energy dissipation capacity. In these applications, the common goal is to find the best system parameters to guide the design of the damper, and to make it clear that a given friction damper design can achieve its maximum damping. On the basis of a large number of studies at home and abroad, this paper introduces the research purpose and parameter significance from the aspects of friction force,friction damper and structural failure control, summarizes the mathematical model algorithms applied to friction damper and their parameter definition methods, summarizes the direction of improvement, puts forward the understanding of the parameter identification algorithm of the mechanical model of friction damper, and expounds its development direction.
