| 摘 要： | The cubic or third-power(TP) nonlinear energy sink(NES) has been proven to be an effective method for vibration suppression, owing to the occurrence of targeted energy transfer(TET). However, TET is unable to be triggered by the low initial energy input, and thus the TP NES would get failed under low-amplitude vibration. To resolve this issue, a new type of NES with fractional nonlinearity, e.g., one-third-power(OTP)nonlinearity, is proposed. The dynamic behaviors of a linear oscillator(LO) with...
