The simplest family of vibration absorbers comprise inertia absorbers, with an inerter in
series with a parallel or series dashpot–spring element, and stiffness absorbers, for which …

Dynamic vibration absorbers array (DVAA) is a newly developed and promising technique
for vibration attenuation of integrally bladed disk (blisk) by mounting underneath the disk. In …

The vibration with large amplitude and low frequency of the flexible space structures is
prone to affect the attitude stability and pointing precision of the spacecraft. To mitigate the …

Material wear, maintenance costs, performance, efficiency, and corrosion are some of the
issues that turbomachinery impellers may encounter. The optimization of impellers through …

整体叶盘是新一代高性能航空发动机的关键部件, 具有结构紧凑, 重量轻和推重比高等优点,

The aim of this paper is to present an innovative approach for optimal placement of
piezoelectric patches in the context of vibration control or energy harvesting applications …

To measure three‐dimensional (3D) forces efficiently and improve the sensitivity of tactile
sensors, a novel piezoelectric tactile sensor with a “sandwich” structure is proposed in this …

Manufacturing tolerances and engine wear produce slight variations in the nominally
identical blades of a bladed disk, or blisk. In theory, the vibrational energy of a tuned blisk is …

Dynamic vibration absorber array (DVAA) is a promising technique for vibration mitigation of
integral blisk. In this paper, the effectiveness of the DVAA method is experimentally validated …
