Dynamic vibration absorber (DVA) with large auxiliary mass has better control performance, but it is also more bulky. Therefore, the mass ratio (the ratio of auxiliary mass of DVA to mass of controlled object) is usually limited to make the DVA easy to install and suitable for engineering practice. In this paper a grounded type DVA with lever component is proposed, which aims to increase the effective mass and reduce unnecessary mass to improve control performance of the DVA. Firstly, the motion differential equations of the DVA are established and solved. Secondly, the optimum parameters are obtained based on H_∞ and H₂ optimization criterion. Then, the performances of the grounded type DVA equipped with and without the lever are investigated. Finally, the control performance of the DVA is compared with other three typical DVAs under H_∞ and H₂ criterion. In this type DVA there are no global optimum parameters, and larger frequency ratio will get better control performance. If the amplification ratio (the ratio of lever power arm to lever resistance arm) is greater than 1, the introduced lever will contribute to control performance of the DVA. Its control performance is better than those of other three typical DVAs. The use of the lever can increase the effective mass of the DVA, thereby improving the control performance of the DVA. The DVA can achieve good performance at small mass ratio by adjusting amplification ratio, which may provide theoretical basis for the design of new kinds of DVAs.

大辅助质量的动态吸振器（DVA）具有更好的控制性能，但体积也更大。因此，通常会限制质量比（DVA的辅助质量与被控对象质量的比值），以使DVA易于安装并适合工程实践。本文提出了一种带有杠杆元件的接地型DVA，旨在增加有效质量并减少不必要的质量，以提高DVA的控制性能。首先建立并求解DVA的运动微分方程。其次，根据H _∞和H ₂优化准则得到最优参数。然后，研究了配备和不配备杠杆的接地型DVA的性能。_{最后，在H ∞}和H ₂准则下，将DVA 的控制性能与其他三种典型的DVA 进行了比较。该类型DVA不存在全局最优参数，较大的频率比将获得更好的控制性能。如果放大比（杠杆力臂与杠杆阻力臂之比）大于1，则引入的杠杆将有助于DVA的控制性能。其控制性能优于其他三种典型DVA。杠杆的使用可以增加DVA的有效质量，从而提高DVA的控制性能。通过调节放大倍数，DVA可以在小质量比下获得良好的性能，这可以为新型DVA的设计提供理论依据。
