As primary members of cable-stayed bridge, stay cables are the most important elements of the entire structure. Wind-induced or Rain-Wind vibration is a cause of the safety in the bridge, the deep anxiety for the observing public. One of effective ways to solve this problem is to install the damper. To design the damper, it is necess따y to estimate the cable dynamic characteristics. In this study, for the cable dynamic characteristics we deγeloped the cable exciting mechanical system(exciter). And to evaluate the performance of the cable exciter, we derived the solution of frequency equation from the differential equation of the mathematical model, 뻐d performed the solution of frequency equation, the eigenvalue analysis by FEM model, the resonance dwelling test and swept sine test
