摘要：
The inherent characteristics and vibration responses of thin plates by FFF(fused filament fabrication) under cantilever boundary conditions were studied by combining FFF theory with experiments. Firstly, considering the property of lamination and orthogonal anisotropy, the fused filament fabricated thin plate(fused plate) was theoretically modeled based on the orthogonal polynomial method. Then, the dynamic characteristics of the fused plate were worked out by Ritz method, and the vibration response of any point in the fused plate was analyzed by using the frequency domain vibration equation. Finally, Poly lactic acid (PLA) thin plate was studied experimentally to determine its measured dynamic characteristics and vibration responses.It was found through the comparison that the developed theoretical model of the fused plate based on orthogonal polynomial method was capable to give accurate predictions on the dynamic characteristics and vibration response, thus validating the feasibility of the model. © 2020, Editorial Department of Journal of Northeastern University.
