Discussion on Calculation Methods of Damping Ratio of the Tower Equipment

Abstract:

Modal damping ratios are very difficult to predict at the design stage, but have a strong influence on the dynamic structural behavior. This paper describes the research process of damping ratio of the tower equipment. First of all, calculation methods of damping ratio of the tower equipment complying with different standards have been analyzed. Then, the damping ratio of process tower equipments has been calculated by using different calculation methods compared to its real data. The results show that it does not accurately predict the damping ratio of the large tower equipment using existing calculation methods. As a result, the theoretical or semi-empirical formula must be put forward to calculate the damping ratio of the industrial tower.
