The large amplitude vibration of cables in cable stayed bridge has been taken more and more attention in recent decade,and viscous dampers,as a main mean of mitigating vibration of stay cable,have been used widely.In this paper,motion equation of cable damper system is derived from Himilton principle with modal coordinate.Then effects of some factors sag,bending stiffness of stay cable,location and damping constant of damper to dynamic characteristic of cable damper system are estimated,and some results have been acquired.These give a good guide to optimal design of damper system.
