Abstract：The traditional viscoelastic damping will be failure, when truss structure of offshore platform exposed to high-energy ultraviolet light and salt spray for along period of time. The semi-active particle damper may be applied in extreme temperature environments where most conventional dampers would fail. In addition, it can meet the needs of the complex external load. The application of semi-active particle damping will be studied in vibration reduction of truss structure of offshore platform. A coupling simulation algorithm based on the discrete element method and finite element method is used to calculate the semi-active particle damper in the truss structure of offshore platform. The influence of control strategy, control current and particle parameters on the vibration characteristics of truss structure of offshore platform is analyzed. The research results show that the
damping effect of semi-active particle damper is better than that of passive particle damper, and reasonable correlation is demonstrated between simulation and test.
