Abstract：
 The present invention relates to an inclined stay cable vibration damping equipment. It is characterized by that it is an inclined stay cable vibration damping system consisting of connecting cable, weight, lever, damper and support abutment. Said system uses the suspended weight to provide tension for connecting cable, and utilizes the connecting cable to transfer the damping force provided by damper connected with bridge surface, elastic force and mass force of suspended weight to change the modal mass, damping value and rigidity so as to attain the goal of damping vibration.
