Self-adaptive multi-dimensional multi-stage damping device
The invention discloses a self-adaptive multi-dimensional multi-stage damping device which makes up defects of traditional single-method control, organically combines passive control and semi-active control to form multi-stage control, can make up the limitation of the passive control in the aspects of strength and frequency bandwidth, can ensure the self-adaptability and adjustability of the control, and achieves a good vibration reduction control effect on the premise of saving energy input. According to the technical scheme, the device comprises a working box, a sliding mechanism is installed at the top of the working box, and the sliding mechanism can move along the working box; the sliding mechanism is connected with an inertial mass body through a telescopic column arranged in the working box, an inner bridging piece is arranged below the sliding mechanism, and the bottom of the inner bridging piece is connected with a plurality of pressure springs; piezoelectric ceramics are laid at the position, lower than the inner bridging piece, of the side wall of the working box, the working box is provided with a plurality of inclined faces, and multiple layers of D-shaped rolling bars capable of rotating relative to the inclined faces are installed on the inclined faces; and under the action of external force, the inertial mass body can move along the D-shaped rolling bars.
本发明公开了一种自适应多维多级减振装置，弥补传统单一方法控制的缺陷，将被动控制和半主动控制有机结合在一起形成多级控制，既可以弥补被动控制在强度和频带宽度方面的局限性，又能够确保控制的自适应性和可调节性，在节约能量输入的前提下达到良好的减振控制效果。其技术方案为：包括工作箱，所述工作箱顶部安装滑动机构，且滑动机构能够沿工作箱移动；所述滑动机构通过置于工作箱内部的伸缩柱连接惯性质量体；滑动机构下方设有内挑板，所述内挑板底部连接若干压簧；工作箱侧壁低于内挑板位置铺设压电陶瓷；所述工作箱具有多个倾斜面，所述倾斜面安装多层能够相对其转动的D形滚杠；在外力作用下，惯性质量体能够沿D形滚杠移动。
