提出了采用动柔度秩2修改实现轴向振动结构被动控制的方法。该方法通过修改结构特性参数,如刚度和阻尼,使系统响应达到控制要求的目标;在此基础上进一步分析了系统响应对修改参数的灵敏度,讨论了振动控制系统的鲁棒性。仿真算例表明,所提出的基于动柔度修改的控制方法能够达到较为满意的控制效果,并有较好的鲁棒性。
The method of passive control of axial vibration structure is proposed by modifying the rank of dynamic flexibility 2. The method can make the system respond to the goal of control requirements by modifying the structural characteristic parameters such as stiffness and damping. Based on the analysis, the sensitivity of the system response to the modified parameters is further analyzed, and the robustness of the vibration control system is discussed. The simulation results show that the proposed control method based on dynamic flexibility can achieve a satisfactory control effect and has better robustness.
