英文摘要： Tuned mass damper (TMD) is an effective damping device which has been widely and maturely using for vibration control in civil engineering. By using electromagnetic transducer, the mechanical energy of TMD was consumed in the past, but it is nowadays converted into power energy, and then it is harvesting and using. The technology of energy harvesting is one of the effective methods, which is used as vibration energy recovery of civil engineering structures. And it is currently a research hotspot. The semi-active TMD system is proposed based on dual functional vibration control and energy harvesting in the project. The semi-active TMD system consists of a spring-mass unit, a damping energy harvesting unit, a response feedback and a resistor (damping) conditioning unit, and a power storage unit. The main research contents include as follows: dynamical models and simulation of the damping energy harvesting unit, the semi-active TMD system, and the coupled system of Structure-TMD; damping mechanism, damping performance and its impact parameter analysis; vibration control mechanism and its multi-damping parameter optimization, semi-active control algorithms and evaluation of energy conversion efficiency; test of semi-active TMD damping performance and energy conversion efficiency, test of a single degree of freedom structure -TMD coupled system test. A lot of theories are analyzed, and experiments are studied. The multi-parameter design theories of the dual functional semi-active TMD system are obtained, and the power conversion efficiency of energy harvesting is improved. The dual functional semi-active TMD system without external power energy will be designed and established, which is important to developing and using renewable energy of civil engineering vibration.
