摘要：Firstly, based on modal experiment, this paper analyses composite fiber curve laminates, which includes [⟨0|15⟩]8, [⟨15|30⟩]8, [⟨30|45⟩]8, [⟨45|60⟩]8, [⟨60|75⟩]8, [⟨75|90⟩]8, and then gets damping ratio of each laminated plate. After analysis, the results showed that the curve of fiber layer for ⟨30|45⟩ composite laminated plate damping ratio is the maximum, however, the curve of fiber layer for ⟨60|75⟩ composite laminated plate damping ratio is the maximum. Secondly, the simple harmonic test of laminated plates with curved layers was carried out. Those plates includes [0/45/⟨0|15⟩/−45]s, [0/45/⟨15|30⟩/−45]s, [0/45/⟨30|45⟩/−45]s, [0/45/⟨45|60⟩/−45]s, [0/45/⟨60|75⟩/−45]s, [0/45/⟨75|90⟩/−45]s. It is easy to get the acceleration response maps of each laminated plate. The above simple harmonic test results showed that larger the damping ratio, the better the damping effect and the smaller the amplitude of acceleration. The amplitude of acceleration changes inversely with the change of damping ratio. Finally, the conclusion is that the laminated plate with the best vibration damping effect is [⟨30|45⟩]8, and the laminated plate with the worst vibration damping effect is [⟨60|75⟩]8. © 2019
