When the isolating switch equipment is subjected to external load to generate power response, the vibration of the main body structure drives the mass block 1 to vibrate, when the mass block 1 vibrates, damping particles in the cavity move irregularly, and in the moving process, friction and collision occur between particles and the cavity, so that the energy of the structure is consumed; when the external wind load is small, the motion amplitude of the mass block 1 is small, the bolt rod 203 in the spring-collision damper 2 is not in contact with the viscoelastic material layer 202, and only the spring 202 acts, so that the collision tuned mass damping system can be regarded as a traditional tuned mass damper; when the external wind load is large enough, the vibration damping device absorbs a large amount of kinetic energy transmitted from the switch structure, the bolt rod 203 in the spring-impact damper 2 collides with the viscoelastic material layer 202, so that the viscoelastic material layer 202 deforms, and the kinetic energy is converted into heat energy to be dissipated. At the moment, the device has the characteristics of the traditional tuned mass damper and the characteristics of the collision damper, and can achieve the effect of double vibration reduction, so that the whole vibration reduction device achieves the purpose of composite control, and the vibration reduction effect is more remarkable and reliable.

Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
