摘要
建立双边塑性碰撞调谐质量阻尼系统的动力学模型,根据Poincare映射图,研究了系统的周期运动和分岔,以及碰撞对结构稳定性的影响,并且分析了误差动力学方程的收敛速度与系数矩阵A的关系。利用同步反馈控制法对双边塑性碰撞调谐质量阻尼系统进行位置控制,数值计算结果验证了该方法是可行有效的。
According to the Poincare map of the proposed dynamics model of tuning mass damper with doubleside plastic impact,periodic motions and bifurcations of the system and the influence of collision on structure stability were discussed.Relationship between the convergence speed of the error dynamics equation and the coefficient matrix was analyzed.The position control of the new TMD system was investigated by using synchronization feedback control.The results showed that the design idea is feasible and effective.
