000018809 520__ $$2eng$$aHigh-Rise Porcelain Cylindrical Electrical Equipment (HRPCEE) is playing increasingly important role in the power supply system and is essential to its safe operation. Earthquake damage investigations show that HRPCEE is vulnerable during earthquakes because of its structural features and material characteristics. This paper aims on inventing a type of shock absorption device using multiple ring tuned mass dampers(MRTMD). Two types of typical HRPCEE are chosen as research objects. Seismic performance of the two objects are studied and relevant damping devices using multiple ring tuned mass dampers (MRTMD) are designed. The influence of MRTMD on HRPCEE is investigated through finite element analysis using ANSYS. For the first equipment, optimal installation location and damping ratio of ring tuned mass dampers (RTMD) are discussed. The effects of RTMD frequency offset, MRTMD damping and MRTMD control of higher modes are also studied. For the second equipment, acceleration, displacement and stress response among structure without control, with RTMD and with MRTMD control are compared. Results show that the vibration of HRPCEE could be attenuated by RTMD/MRTMD and MRTMD outperforms RTMD. Control of higher modes is implementable but not indispensable for type one equipment while that is irreplaceable for type two equipment.
