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.
Due to the tuned mass damper (TMD), which is not effective for the control of the rotation and the pendulum motion of the suspension structure, this paper combines the numerical simulation and the model test with the new tuning inertial damper (tuned rotary inertia damper, TRID) control system.After establishing the mechanical analysis model of the interaction between TRID system and suspension structure, the influence of the control system parameters on the control effect is analyzed and compared by numerical simulation. Based on the Simulink system, the nonlinear motion The numerical simulation of differential equation and dynamic motion simulation analysis of ADAMS mechanism are carried out to study the optimal parameters of the control system of TRID system, such as moment of inertia ratio, frequency modulation ratio, damping ratio and so on. The model system test verifies the feasibility and effectiveness of the shimmy of TRID system control structure.
