...Yuhang Wang; Li Cheng; Jingtao Du; Yang Liu Through creating slow waves in structures, acoustic black hole (ABH) shows promise for potential vibration control applications. However, it remains unclear whether such phenomena can still occur in a structure undergoing high-speed spinning, and if so...

... crystals provides new ideas for the design of such isolation systems. This letter reports a new type of satellite isolation system to isolate shock and vibrations in an ultrawide frequency range. The labyrinth design of this system integrates acoustic black holes (ABHs) as microstructures, which leads...

...Hongli Ji; Xiaoning Zhao; Ning Wang; Wei Huang; Jinhao Qiu; Li Cheng A previously proposed planar axisymmetric dynamic vibration absorber (DVA), with embedded acoustic black hole (ABH) features, has been shown to suffer from the very selective coupling with the host structure, thus compromising its...
