| 摘 要： | 从带有附加集中质量的正交各向异性板的力学简化模型出发，给出了系统的频响函数，在进一步对系统进行振动仿真实验的基础上，用最小化加速度和最小化振动功率传递2类不同的控制律，对这种结构给出了优化控制算法．在控制模拟仿真实验中，通过改变模型中控制力的位置、个数、考察点的位置、附加集中质量大小等因素，达到了系统仿真控制实验要求的目标．仿真结果表明，2种控制方法均能有效地抑制振动，对激振力及考察点都确定的工况，通过仿真控制试验得到了最佳控制力的位置及大小，为工程实践提供了有价值的参考．

| Abstract: | Based on the model of orthogonal anisotropic plates with concentrated added mass.A study of the system frequency response function is conducted.Two mathematical models of active control are proposed and compared on the basis of emulating the system vibration.Minimum acceleration method and minimum power transmission method are employed to investigate the control effects under dynamic forces by changing the number and position of control forces,position of reference point and magnitude of concentrated added mass.The result shows that the methods presented can control the vibration effectively.The optimal position and magnitude of the control forces can also be figured out if the stimulant forces and the reference points are known,providing a basis for the practical project. |
