摘要

This paper presents an experimental study of using a hybrid platform to mitigate vibration of a batch of high tech equipment installed in a building subject to nearby traffic-induced ground motion. A three-story building model and a hybrid platform model are designed and manufactured. The hybrid platform is mounted on the building floor through passive mounts and controlled actively by an electromagnetic actuator with velocity feedback control strategy. A series of shaking table tests are then performed on the building model without the platform, with the passive platform of different parameters, and with the hybrid platform. The experimental results demonstrate that hybrid platform is very effective in reducing the velocity response of a batch of high tech equipment in the building subject to nearby traffic-induced ground motion if dynamic properties of the platform and control feedback gain are selected appropriately.
