• A new energy harvester using vibro-impact nonlinear sink is proposed. Vibro-impact induced targeted transfer improves significantly the efficiency. The optimal harvesting efficiency resides in regimes with 1–2 impacts per cycle. VINES provides high density and robust over a certain level of noise. potential (VINES) investigated. Applying Signorini’s contact law, non-smooth dynamics first form...

A sensor network is made up of a large number of sensors with limited energy. Sensors collect environmental data then send them to the sink. Energy efficiency and thereby increasing the lifetime of sensor networks is important. Direct transfer of the data from each node to the central station will increase energy consumption. Previous research has shown that the organization of nodes in cluster...

In order to solve the problems of limited installation space and strict additional quality, effects internal distributed nonlinear energy sinks (NES) considering optimal locations on a composite truss core sandwich plate are investigated in this paper. Choose five NESs here inset them different places suppress vibration plate, which is excited by half-wave shock. The coupled dynamic equations s...

Abstract Nonlinear energy sinks (NESs) are broadband passive vibration absorbers that nonlinearly connected to a host system. If an NES is attached multi-degree-of-freedom mechanical system under transient loading, the vibrations in will transfer and dissipate NES. During this transfer, sequentially resonates with modal frequencies of system, dissipating one mode at time. This phenomenon called...
