Abstract
In this study, a power generation type TMD with electromagnetic damping device is newly proposed. By applying electromagnetic damping device, damping characteristics can be easily adjusted only by changing resistance, and in addition, the TMD with the electromagnetic damping device can generate electric power during the vibration energy absorption. In this study, considering an actual bridge condition, characteristics of electromagnetic damping device under different levels of resistance were investigated through experiments and simulations. Based on the results, a power generation type TMD was developed by exchanging oil dampers to the electromagnetic damping devices, and was applied to an actual expressway bridge to examine its performance of vibration energy absorption and power generation.
