摘　　要：由于常用的调谐质量阻尼器(tuned mass damper,TMD)对悬吊结构转动和摆振运动控制无效,本文结合数值模拟和模型试验对前期研究提出的新型调谐转动惯量阻尼器(tuned rotary inertia damper,TRID)控制系统应用的可行性进行深入研究.在建立了TRID系统与悬吊结构相互作用力学分析模型以后,通过数值模拟分析比较了控制系统参数对控制效果的影响;基于Simulink系统进行非线性运动微分方程数值求解和ADAMS(automatic dynamic analysis of mechanical systems)机构动力学运动仿真分析,研究了TRID系统控制结构摆振运动的最优参数,如转动惯量比、调频比、阻尼比等;通过小型比例模型系统试验验证了TRID系统控制结构摆振的可行性和有效性.Because the commonly-used tuned-mass-damper（TMD） is ineffective in controlling the pendulum vibration of a suspended structure, we explore, by numerical analysis and practical experiments, the swing-motion control of such structures by using an innovative tuned-rotary-inertia-damper（TRID）. First, by the non-linear differential equations and the simplified analytical model, we determine the interaction effects between the TRID system and the suspended structure. These effects are studied through Simulink and ADAMS dynamical codes, and the results are summarized and systemati- cally analyzed. Optimal key-parameters of the TRID, such as the inertia ratio, the tuning ratio and the damping ratio, etc., are determined for controlling the swing-motion of structures. The effectiveness and feasibility of TRID control system are further validated by the bench-scale-shaking-table-tests.
