The proposed device is equipped with an auxiliary oil tank outside the main cylinder, and oil flows between the cylinder and the tank are controlled by solenoid valves. Existing oil dampers change vibration energy to heat. However, the proposed device recovers the vibration energy as strain energy of oil in the tank and reuses it at an optimum timing to improve the control efficiency. Its mechanical model is expressed as a four-element model that consists of a Maxwell model and a Voigt model in series. First, we present the basic configuration of the device, and show how the energy recovery system works in accordance with the control algorithm. Second, we show the results of dynamic loading tests conducted on a full-scale specimen and the results of simulation analyses using the four-element model. Finally, we demonstrate the results of seismic response analyses using a high-rise building model, and discuss the control effect in comparison with existing oil dampers.
