Vibration control has been of great interest to scientists and engineers for many years. Although linear vibration absorbers have shown be effective in mitigating vibrations at specific frequencies, their reduction effect is usually limited a narrow frequency bandwidth. Nonlinear energy sinks attracted attention due better over wider In practical applications, the nonlinear sink devices can effectively absorb, dissipate, convert from broadband excitation, so as achieve harvesting. However, research on harvesting based less mature than systems. Multiple parameters device design (e.g., damping size) affect actual performance sinks, but there no exact method simplify multiparameter sinks. Since it more difficult implement electromagnetic electrostatic harvesters, focused piezoelectric harvesters. This paper summarizes technology, including introduction sink, its application various fields The also some important methods solving dynamical equations, well advantages disadvantages. conclusions provide an outlook subsequent such materials with high density, benefits balanced suppression energy, self-tuning complex environments. It provides powerful reference popularization technology
