A comprehensive theoretical model for the centrifugal effect of nonlinear beam-type piezoelectrical energy harvesters in rotational motions
Mechanical Systems and Signal Processing(2023)
摘要
•A comprehensive theoretical model for beam-type PEHs with an installation angle is established.•The proposed model can account for the centrifugal effect depending on the installation angle and rotational radius.•Adjusting the installation angle is experimentally proved to be a promising way to change the effective frequency range.
