A frequency tuned vibration damper assembly (100) comprises a horn plate (20) connected to a vibrating surface (3) of a steering wheel structure at a first junction (I1) via a plurality of first elastic damper elements (30) so as to be movable relative to the vibrating surface (3). The mass (10) supported by the plate (20) is movable relative to the plate (20) on an opposite front side of the plate (20). An elastic buffer element (40) is arranged at the second joint (I2) between the plate (20) and the mass body (10). The stiffness of the elastic damping element (40) is selected such that it forms a second elastic damper element which, together with the first elastic damper element (30) and the mass body (10), forms a frequency tuned damping mass body-spring system having two damping joints, and frequency tuned to vibration of the vibrating surface.
一种频率调谐振动阻尼器组件(100)包括喇叭板(20),该喇叭板经由多个第一弹性阻尼器元件(30)在第一接合部(I1)处连接到方向盘结构的振动表面(3),以便相对于振动表面(3)是可移动的。由板(20)支撑的质量体(10)在板(20)的相对的前侧上相对于板(20)是可移动的。弹性缓冲元件(40)在板(20)和质量体(10)之间设置在第二接合部(I2)处。弹性缓冲元件(40)的刚度被选择为使得其形成第二弹性阻尼器元件,该第二弹性阻尼器元件与第一弹性阻尼器元件(30)和质量体(10)一起形成频率调谐阻尼质量体‑弹簧系统,该频率调谐阻尼质量体‑弹簧系统具有两个阻尼接合部,并且被频率调谐成所述振动表面的振动。
