Optimization and analysis of a grounded type dynamic vibration absorber with lever component

Abstract: 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 e… Show more

“…To overcome the limitations of the common DVAs in vibration reduction of primary structure, researchers have explored other solutions, such as the introduction of negative stiffness devices, [18][19][20] flywheel inertial with lever fixed at ground, 21 and lever mechanism. 22 inspired by. 23 Some research included both negative stiffness and lever mechanism.…”
