Experimental investigation of vibration amplitude control in additive manufactured PLA and PLA composite structures with MFC actuator
ENGINEERING STRUCTURES(2023)
Abstract
•An experimental study on vibration amplitude control in additive manufactured PLA and PLA composites (PLA-SCF, PLA-CCF) structures was conducted.•The natural frequencies and mode shapes of each structure were determined using the Polytec 3D laser vibrometer.•The optimal phase and voltage amplitude for the MFC actuator (M8507-P2) was tuned for each structure to achieve maximum amplitude damping.•The proposed experimental scheme can be applied to a wide range of composite materials.
