Multidirectional broadband tuned mass damper and design method
The invention relates to a multi-directional broadband tuned mass damper and a design method thereof, a first damping structure and a second damping structure are arranged on a rigid vibration reduction frame, the first damping structure has a control main frequency, and the second damping structure has two control main frequencies, so that the control main frequency of the first damping structure and the control main frequency of the second damping structure are reduced; the control main frequency of the second damping structure is greater than that of the first damping structure; under the synergistic effect, the second damping structures mainly and effectively broaden the high-frequency control range, the multiple first damping structures control one low-frequency control main frequency in a one-to-one mode, and therefore the full frequency is controlled, the first damping structures and the second damping structures on the rigid vibration reduction frame are the same in extension direction, and the damping effect is good. The isotropic quality and rigidity distribution characteristics are ensured; moreover, when different control frequency ranges are used, the number and the distribution form of the first damping structures and the second damping structures, and the corresponding mass ratio and the damping ratio can be designed in advance, so that different control requirements are met.
本申请涉及一种多向宽频调谐质量阻尼器及其设计方法，由于在刚性减振架上设置第一阻尼结构和第二阻尼结构，并且使第一阻尼结构具有一个控制主频，第二阻尼结构阻尼结构具有两个控制主频，第二阻尼结构的控制主频大于第一阻尼结构的控制主频；在协同作用下，第二阻尼结构主要有效拓宽其对高频率的控制范围，多个第一阻尼结构一对一控制一个低频率的控制主频，从而对全频率进行控制，在刚性减振架上的第一阻尼结构和第二阻尼结构的延伸方向相同，保证了其各向同性的质量和刚度分布特征；再者，在使用针对不同的控制频率范围时，可以预先设计第一阻尼结构和第二阻尼结构的数量和分布形式，以及对应的质量比和阻尼比，从而适应不同的控制需求。
