Embodiment
[0109] The specific implementation process of the embodiment of the present invention is as follows figure 1 As shown, the physical structure of the multi-layer eccentric structure-AMD (Active MassDamper) system is shown as figure 2 As shown, where M and S are the mass and stiffness center of the structure respectively, and the coordinate origin of the structure coordinate system is taken at the center of mass. A three-layer eccentric structure is taken as an example to verify the effectiveness of the proposed method.
[0110] Step 1: Obtaining the structural dynamics model The specific implementation steps are:
[0111] (1) The schematic diagram of the three-layer entity structure is as follows figure 2 shown, where figure 2 (a) is the façade, figure 2 (b) is the top plane. Depend on figure 2(b) It can be seen that one AMD is installed on the top layer in the x direction and y direction to apply the corresponding calculation control force to the main structure, and...
