摘要：

Cantilever structures are widely used in the field of aerospace engineering. It is very important to restrain the vibration of these structures because of their resonance behavior under external excitation. The Nonlinear Energy Sink (NES), which is characterized by light weight, targeted energy transfer and high damping efficiency, can be used in the design of vibration suppression of aerospace structures. In this paper, the vibration reduction of cantilever rectangular plates using the NES is studied. Considering the classic Kirchhoff plate model, the dynamic equation of the thin plate coupled with the NES is established, and the response of the structure in the first order transverse bending is studied by modal truncation. The damping effect of the NES under different parameters is analyzed. It is found that the NES is sensitive to the response position of the structure and has the maximum effect of vibration reduction at the position with the maximum displacement response, which can provide some theoretical support for the cantilever structure in engineering application. © 2019, Nanjing Univ. of Aeronautics an Astronautics.
