A novel vibration absorber is designed to suppress vibrations in fluid-conveying pipes subject to varying fluid speeds. The proposed absorber combines the fundamental principles of nonlinear energy sinks (NESs) and nonlinear energy harvesters (NEHs). The governing equation is derived, and a second-order discrete system is used to assess the performance of the developed device. The results demonstrate that the proposed absorber achieves significantly enhanced energy dissipation efficiency, reaching up to 95%, over a wider frequency range. Additionally, it successfully harvests additional electric energy. This research establishes a promising avenue for the development of new nonlinear devices aimed at suppressing fluid-conveying pipe vibrations across a broad frequency spectrum.
