Multidirectional ultralow-frequency tuned mass damper and parameter setting method thereof
The invention relates to the technical field of bridge engineering, in particular to a multidirectional ultralow-frequency tuned mass damper and a parameter setting method thereof. The multidirectional ultralow-frequency tuned mass damper comprises a mass block, a swing assembly and a damping piece. The swing assembly comprises at least one swing piece, the swing piece comprises a tension spring and a swing rope, the ends of the tension spring and the swing rope are connected, the other end of the tension spring is connected with the mass block, and the other end of the swing rope is used for being connected with a to-be-damped structure. The damping piece is used for providing damping for the mass block. The parameter setting method comprises the following steps that parameters of a tension spring and a mass block are determined according to the vertical control frequency of a structure to be subjected to vibration reduction; and the length of the swing rope is determined according to the horizontal control frequency of the to-be-damped structure. The problems of single control direction and ultralow-frequency vibration control of an existing tuned mass damper can be solved.
本发明涉及桥梁工程技术领域，具体涉及一种多向超低频调谐质量阻尼器及其参数设定方法。该多向超低频调谐质量阻尼器，包括：质量块、摆动组件和阻尼件。摆动组件包括至少一摆动件，摆动件包括端部连接的拉簧和摆绳，拉簧的另一端与质量块连接，摆绳的另一端用于与待减振结构连接；阻尼件用于为质量块提供阻尼。该参数设定方法包括以下步骤：根据待减振结构的竖向控制频率，确定拉簧和质量块的参数；根据待减振结构的水平向控制频率，确定摆绳的长度。能够解决现有调谐质量阻尼器控制方向单一和超低频振动控制的问题。
