PROBLEM TO BE SOLVED: To provide a vibration-testing system for allowing continuous vibration from low frequency to high one by using a cylindrical coil being incorporated between vibration and grounding-part bodies as an electromagnetic damper. SOLUTION: A cylindrical coil 6 being fixed to a grounding-part body 4 for mounting is incorporated between vibration- and grounding-part bodies 3 and 4 for using as an electromagnetic damper, thus suppressing the vibration of the vibration-part body 3 with the resonance of an elastic support part and the vibration-part body 3, eliminating the need for stopping a vibration test once for suppressing the vibration of the elastic support part as conventionally, and performing the vibration test using a vibration testing system by the same vibration means from a low frequency to a high one.
